This research study focuses on investigating the seismic performance of non-straight beams in steel structures and exploring the mechanism by which plastic hinges are formed within these beams. The findings contribute to the understanding of their behaviour under seismic loads and offer insights into their potential for enhancing the lateral resistance of the structure. The abstract of the study highlights the significance of corners in structural plans, where non-coaxial columns, diagonal elements or beams deviating from a straight path are commonly observed. Typically, these non-straight beams are connected to the columns using pinned connections, despite their unknown seismic behaviour. Recognizing the importance of generating plastic hinges in special moment resisting frames and the lack of previous research on the involvement of these non-straight beams, this study aims to address this knowledge gap.

This study examines the seismic behaviour and plastic hinge formation of non-straight beams in steel structures. Non-straight beams are beams that connect non-coaxial columns and diagonal elements, or deviate from a linear path. They are usually pinned to the columns, and their seismic contribution is unknown. A critical case with a 12-m non-straight beam is analysed using Abaqus software. Different models are created with varying cross-section shapes and connection types between the non-straight beams. The models are subjected to lateral monotonic and cyclic loads in one direction. The results show that non-straight beams increase the lateral stiffness, strength and energy dissipation of the models compared to disconnected beams that act as two cantilevers.

The analysis results reveal several key findings. The inclusion of non-straight beams in the models leads to increased lateral stiffness, strength and energy dissipation compared to the scenario where the beams are disconnected and act as two cantilever beams. Plastic hinges are formed at both ends of the non-straight beam when a 3% drift is reached, contributing to energy damping and introducing plasticity into the structure. These results strongly suggest that non-straight beams play a significant role in enhancing the lateral resistance of the system. Based on the seismic analysis results, this study recommends the utilization of non-straight beams in special moment frames due to the formation of plastic hinges within these beams and their effective participation in resisting lateral seismic loads. This research fills a critical gap in understanding the behaviour of non-straight beams and provides valuable insights for structural engineers involved in the design and analysis of steel structures.

The authors believe that this research will greatly contribute to the knowledge and understanding of the seismic performance of non-straight beams in steel structures.

To maintain the well integrity, the strength and sealing ability of premium connection should be in the safe scope. ISO 13679 is widely used for evaluating the ability of tubing and casing connection all over the world. FE is adopted to simulate the ISO 13679 tests.

Because of the disadvantage of experiment such as long period, high cost and high requirement on the facility, considering the convenience and universality of finite element method, as well as the contacting nonlinearity and material nonlinearity, three-dimensional finite element model of a certain type of premium connection is established with the consideration of helix angle. The loads exerted on the premium connection are the loads in series B test and thermal cycle test of ISO 13679. The distributions of Von Mises stress and contact pressure in various cases were studied.

The results showed that the bending load has a great influence on the distribution of Von Mises stress and contact pressure for premium connection. The Von Mises stress and contact pressures on the sealing surface are smaller on the tension side and greater on the compression side. With increasing axial compression load, the contact pressures on the tension side are too small, which may lead to sealing failure. The influence of temperature on the performance of premium connection cannot be ignored when choosing or designing premium connections. Both the Von Mises stress and contact pressure decrease slightly during a period of thermal cycle. Although the performance of the premium connection is good in a period of thermal cycle, its performance in a long period should be evaluated. Finite element simulation can effectively simulate the ISO 13679 test procedure and obtain the stress and contact pressure distribution. It can be used as a reference for evaluating the performance of premium connections.

Considering the convenience and universality of finite element method, as well as the contacting nonlinearity and material nonlinearity, three-dimensional finite element model of a certain type of premium connection is established with the consideration of helix angle.

This paper aims to investigate and assess a perspective of combining high-strength-steel endplate with mild-steel beam and column in endplate connections.

First, experimental tests on high strength steel endplate connections were conducted at fire temperature 550°C and at an ambient temperature for reference.

The moment-rotation characteristic, rotation capacity and failure mode of high-strength-steel endplate connections in fire and at an ambient temperature were obtained through tests and compared with those of mild-steel endplate connections. Further, the provisions of Eurocode 3 were validated with test results. Moreover, the numerical study was carried out via ABAQUS and verified against the experimental results.

It is found that a thinner high-strength-steel endplate can enhance the connection’s rotation capacity both at an ambient temperature and in fire (which guarantees the safety of an entire structure) and simultaneously achieve almost the same moment resistance with a mild steel endplate connection.

Extant research captures the signaling and attitudinal effects of luxury brand prominence strategy; however, little is known about the underlying mechanisms that drive this effect. This study aims to uncover brand authenticity and brand coolness as parallel mediators driving the effects of brand prominence on luxury purchase intentions and explores the moderating role of consumers’ self-brand connection.

The research consisted of three experiments. Study 1 (n = 121) explored the direct effects of brand prominence among Chinese consumers. Using a sample of Turkish consumers (n = 115), Study 2, measured the mediation effects of brand authenticity and brand coolness. Study 3 (n = 211) examined how self-brand connection moderated the mediation effects among British customers.

A luxury brand prominence strategy leads to negative perceptions of coolness and authenticity and, in turn, reduces purchase intentions. The negative effect of brand prominence is even more pronounced among consumers with high self-brand connection.

The study elaborates on how brand prominence informs consumers’ perceptions of authenticity and coolness. In examining the role of self-brand connection, the study reveals a theoretically and managerially relevant boundary condition of this focal effect.

The research highlights how luxury brands can use differing brand prominence strategies. This research informs brand managers on how to enhance brand authenticity and coolness while managing self-brand connection.

The study extends the luxury branding literature by explaining the brand prominence effect through the parallel mediators of brand authenticity and brand coolness. In contrast to extant research, the findings show that the negative effect of brand prominence is particularly strong among consumers with high self-brand connection.

Trade credit is an important business-to-business marketing tool for building firms’ competitive advantage. Many studies explore the determinants of trade credits from a trust-based view, but the role of political connections is largely overlooked, despite their potential influence in assessing firms’ trustworthiness in the context of emerging economies. This study aims to fill this gap by examining how political connections affect the capacity of emerging economy firms (EEFs) to grant and receive trade credit.

This study tests a conceptual model using secondary data collected from 1,149 Chinese privately owned listed manufacturing firms between 2008 and 2016.

This study finds that political connections reduce EEFs’ accounts receivable and payable; their philanthropic activities alleviate this negative effect for accounts payable, while patent applications reduce it for accounts receivable. These findings suggest the effect of political connections can spillover to EEFs’ relationship with their up- and down-stream partners.

This study has implications EEF managers, particularly in pointing to the detrimental effect of political connections on relationships with buyers and suppliers, and highlights the need to adopt suitable approaches to offset this effect.

This study sheds new light on the negative effect of political connections on EEFs’ capacity to grant and receive trade credit in their exchanges with up-stream and down-stream partners. It enriches the trust-based view of trade credit by revealing the significant influence of EEFs’ political connections, while also advancing a contingency view by testing the moderating role of corporate philanthropic activities and patent applications.

This study aims to investigate whether socially responsible businesses with corporate social expenditure are less prone to engaging in tax avoidance. The study also examines whether political connections moderate the association between corporate social responsibility (CSR) and tax avoidance.

The study uses ordinary least squares to analyse the panel data of all 30 listed banks on the Dhaka Stock Exchange covering 2012 to 2020. The study uses a set of alternative variables to check the robustness of the findings.

Confirming the corporate culture theory, the study findings indicate that the higher the firms’ CSR expenditure, the lower the tax avoidance. Contrarily, the moderating effect of political connection weakens the role of CSR in tax avoidance, implying that political relation makes the firms socially irresponsible. Besides, the findings document that firms with strong political connections are more likely to be tax aggressive by weakening the role of CSR. The findings imply that firms with weaker political connections are more socially responsible than firms with strong political ties.

The study provides the bank management and regulatory bodies valuable insights to take necessary actions so that they can easily monitor whether the banks follow their instructions regarding CSR and tax payments. As the politicians make the firm socially irresponsible, the regulatory bodies and bank management should not keep them or their relatives on the board.

The study contributes to the CSR and tax avoidance literature considering the moderating role of political connections in Bangladesh banking sector.

This paper aims to study the influences of eccentricity on the fastener load and bearing strength of the eccentric connection in the aircraft structure.

The special experiment is designed for the researches. The fastener loads of the eccentric connection are gained by using the derived formulas and numerical analysis, and the fastener load rules is verified by the experiment. The bearing strength of the eccentric connection is investigated by the experiments under different eccentricities compared with that gained from the experiment.

The study results are summarized as follows. Magnitude of the fastener load in the eccentric connection is greatly affected by distance from the fastener to the centroid of the fastener cluster and that from the fastener to the concentrated load. With the increase of eccentricity of the homolateral concentrated load, the fastener load increases, and difference of the fastener loads becomes larger, forming the short plate effect of the bucket. It means that fastener with the maximum load (the shortest plate of the bucket) leads to decrease of the bearing strength of the eccentric connection (the capacity of the bucket).

The investigation on the influence of eccentricity on the bearing strength of eccentric connection is firstly presented. The vector expression of the fastener load in eccentric connection is firstly derived. And the influencing mechanism of the fastener load on the bearing strengths of the different eccentric connections is demonstrated. The study results can provide guidance for the structure design of the eccentric connection.

The purpose of this study, which draws on the stimulus organism response (S-O-R) theory, is to empirically examine the effect of brand coolness on communal brand connection and brand commitment, while assessing how the latter fosters brand trust and loyalty among smartphone users.

Data are collected from 410 smartphone users in Ghana and analyzed with Smart-PLS utilizing the structural equations modeling technique.

The study's findings show that consumers' perceptions of brand coolness have a positive influence on their communal brand connection and brand commitment. The study also discovers that brand commitment influences brand loyalty, whereas communal brand connection influences brand commitment, loyalty and trust, respectively. Similarly, brand commitment and communal brand connection are identified as important mediating variables in the relationship between brand coolness and both brand loyalty and brand trust.

The study underlines the significance of developing cool brand images and communicating same effectively to current and prospective customers, along with other stakeholders.

The study highlights the fact that properly creating cool brands can lead to increased communal brand connection, brand commitment, and, consequently, brand trust and loyalty.

The objective of this paper is to study the impact of political connection and governance on credit rating and whether there is a substitution or complementary relationship between them.

In order to achieve the objective, a succession of eight ordered probit regressions has been carried out. Moderating variables between the political connection and governance characteristics were introduced. The whole population is taken as a sample, i.e., 27 Tunisian companies that are evaluated by FITSH NORTH AFRICA agencies over a period of 10 years (2009–2018).

The outcomes are mixed. They show that the political connection does not always influence credit rating; the size and board independence always improves credit rating; the duality between the functions affects credit rating; whereas the majorities’ proportion does not influence credit rating; and a substitution between the political connection and the governance characteristics is validated.

Like any other research, our results are factors of our measures and variable choice and depends heavily on the how these variables were conceived. Also, although our number of observations responds to the statistical result generalization requirements, our sample remains relatively narrow with 27 companies only.

In practice, the research will allow investors to have a better vision upon the future of their investments based on whether to develop their governance system or promote political networking. It will also prompt lenders to look beyond ratings and consider factors such as political connections to make a rational judgment on their future placements.

This study leads us to find various solutions: the establishment of credit agencies that take into consideration all the data of all the operators taken as a whole (bank, leasing company, and factoring). It encourages the reorganization of the Tunisian banking sector through mergers for example.

This study is a pioneer in the credit rating field in Tunisia, where the source of debt financing is the most used by all enterprises across all sectors. This study extends the literature of political connection effectiveness, independent directors, board size, in improving corporate performance and credit rating.

This research aims to examine the association between political connection and tax aggressiveness during the COVID-19 pandemic and the role of business ethics in the association between political connection and tax aggressiveness.

This study employs a multiple regression method for 147 manufacturing firms listed on the Indonesia Stock Exchange during the pandemic era.

Political connection has no association with tax aggressiveness. However, political connection has a negative (positive) association with tax aggressiveness in more (less) ethical firms. The results are robust after controlling for year-fixed effects, endogeneity issues and other tax aggressiveness measurements.

Political connection is often cited as the driver of unethical business, including tax aggressiveness. However, this paper claims and finds that political connection is a double-edged sword. Ethical firms use political connection to reduce their tax aggressiveness, and vice versa. Previous research has paid little attention to this topic. This paper also uses COVID-19 as a natural experiment to highlight the importance of corporate social responsibility activities as business ethics.
