This study aims to present the variations of optimal seismic control of reinforced cement concrete (RCC) structure using different structural systems. Different third-dimensional mathematical models are used to examine the responses of multistory flexibly connected frames subjected to earthquake excitations.

This paper examined a G + 50 multi-storied high-rise structure, which is analyzed using different combinations of moment resistant frames, shear walls, seismic outrigger systems and seismic dampers to observe the effectiveness during ground motion against soft soil conditions. The damping coefficients of added dampers, providing both upper and lower levels are taken into consideration. A finite element modeling and analysis is generated. Then the nature of the structure exposed to ground motion is captured with response spectrum analysis, using BNBC-2020 for four different seismic zones in Bangladesh.

The response of the structure is investigated according to the amplitude of the displacements, drifts, base shear, stiffness and torsion. The numerical results indicate that adding dampers at the base level can be the most effective against seismic control. However, placing an outrigger bracing system at the middle and top end with shear wall can be the most effective for controlling displacements and drifts.

The response of high-rise structures to seismic forces in Bangladesh’s soft soil conditions is examined at various levels in this study. This study is an original research which contributes to the knowledge to build earthquake resisting high-rises in Bangladesh.

Increasing overhang of serviced apartments poses a serious concern to the national property market. This study aims to examine the impacts of macroeconomic determinants, namely, gross domestic product (GDP), consumer confidence index (CF), existing stocks (ES), incoming supply (IS) and completed project (CP) on serviced apartment price changes.

To achieve more accurate, quality price changes, a serviced apartment price index (SAPI) was constructed through a self-developed hedonic price index model. This study has collected 1,567 transaction data in Kuala Lumpur, covering 2009Q1–2018Q4 for price index construction and data were analysed using the vector autoregressive model, the vector error correction model and the fully modified ordinary least squares (OLS) (FMOLS).

Results of the regression model show that only GDP, ES and IS were significantly associated with SAPI, with an R² of 0.7, where both ES and IS have inverse relationships with SAPI. More precisely, it is predicted that the price of serviced apartments will be reduced by 0.56% and 0.21% for every 1% increase in ES and IS, respectively.

Therefore, government monitoring of serviced apartments’ future supply is crucial by enforcing land use-planning regulations via stricter development approval of serviced apartments to safeguard and achieve more stable property prices.

By adopting an innovative approach to estimating the response of price change to supply and demand in a situation where there is no price indicator for serviced apartments, the study addresses the knowledge gap, especially in terms of understanding what are the key determinants of, and to what extent they influence, the SAPI.

This study explores the potential of computational design processes in creating contextually responsive envelopes for high-rise residential buildings in the Middle East. This includes considering both physical constraints and social preferences, with a focus on balancing sunlight exposure, privacy and views.

A two-phase simulation study analyzed various exterior envelope systems in Baghdad high-rise buildings. The first phase examined two commonly used exterior envelopes – fully glazed and window-based – to assess sunlight exposure, privacy and views. In the second phase, a multi-objective optimization process was applied to derive contextually optimized design solutions addressing the challenges identified in the first phase.

The study reveals that contextually optimized design solutions significantly improved direct sunlight exposure and privacy while maintaining satisfactory views. Although fully glazed exterior envelopes provided better-uninterrupted views, the optimized solutions offered more balanced performance across all factors, demonstrating the potential of computational design processes in creating contextually responsive building envelopes.

This paper emphasizes the importance of considering both physical and social contexts in the development of algorithms for architecture in the Middle East. This paper supports a progressive interpretation of traditional building references and demonstrates how computational design processes can create contextually responsive building envelopes that satisfy social needs and provide better-performing buildings for inhabitants.

Although the Singapore model of ethnic integration through its public housing programme is well known, the formula for replicating its success elsewhere remains underexplored. This study aims to identify the criteria for successful transplantation, specifically by identifying the housing tenure types that are most amenable to the implementation of the Singapore model.

Through a comparative study of two common law jurisdictions – Singapore and England – this article highlights the differences in their housing landscapes and how such differences impact upon the adoption of ethnic integration policies through housing. The article also unpacks, through a cross-disciplinary lens, the concepts of public housing and housing tenures, drawing heavily on socio-legal and housing literature.

The authors observe that the implementation of ethnic integration policies is best justified and most easily achieved in leasehold estates that exhibit a strong tenurial relationship with the state retaining a more than notional role. Public housing in Singapore being an exemplar of this model, the implementation of its ethnic integration policy is relatively straightforward. By contrast, the shrinking public housing sector in England means that adoption of a similar policy would have limited reach. Even then, the political–legal environment in England that promotes home ownership is potentially hostile to the adoption of such policy as it may be seen as an infringement of private property right.

The cross-jurisdiction comparison is supplemented by an interdisciplinary analysis that seeks to bridge differences in the categorisation of tenure in housing and law literatures so as to promote cross-disciplinary dialogue.

This paper aims to adopt a comparative method using case law, statutes and secondary literature across both jurisdictions. This paper also draws on various theories of property ownership.

This paper conceptualises the legal relations embedded within condominium housing and the various theories of property ownership to ascertain how children’s interest fit within this framework. The laws of two jurisdictions, New South Wales and Singapore, are examined to determine how their strata law responds when children’s safety is at stake.

Drawing on pluralist moral theories of property law, the thesis advanced is that children’s issues within condominiums should not be subject to majoritarian rule especially when their safety is at stake. The paramount guiding value should be ensuring their safety within multi-owned housing communities. Using the law of two jurisdictions, New South Wales and Singapore, the central argument of this paper is that the law in these jurisdictions has rightfully adopted a protective approach towards children in multi-owned properties where their safety is at stake.

The literature on the law of multi-owned housing has largely focused on governance issues such as mediating between the majority owners’ interest with that of the minority owners’ interest. Children in multi-owned developments remain an under investigated area as children’s interests do not fit within the paradigm of majority versus minority interests. The paper advances the argument that children’s interest should be viewed through either a rights-based theory or pluralists’ theories of property law. Lessons from the New South Wales and Singapore experience are also drawn which might prove useful to other jurisdictions.

This paper aims to unfold the intricate relations between private law design, the structure of organizations for collective action and cultural values and orientations that practically guide interpersonal interactions in Chinese society.

Drawing upon the Hofstede Insights National Culture survey (The Culture Compass) data and some judicial rulings in China, this paper examines the legislative development and judicial approach to settle condominium disputes to explain and address the cultural orientation for future legal reform. This paper examines how the law reflects and responds to the cultural and social variations/interactions among the stakeholders, namely, local government, developers, homeowner associations, condo owners and property management agents.

Culture plays a significant role in shaping how condominiums are governed in China. This analysis can highlight the role of cultural factors that influence the success or failure of condominium governance and suggest ways in which governance structures can be adapted to reflect the legal culture of the community better. The emphasis on social harmony, respect for authority, relationships and networks and knowledge and expertise all contribute to a unique approach to condominium governance that reflects the values and priorities of Chinese society.

While much has been written on the importance of property rights to economic development, relatively little seems to be understood about processes of change in complex property systems, particularly in China, a socialist-transforming country. Specifically, there is a lack of reliable knowledge about the intricate relations between the structure of organizations for collective action and cultural orientations that practically guide interpersonal interactions in Chinese society. The question at the heart of this research relates to the condominium rules most suitable for an emerging Chinese private property market.

Over the years, the significance of retrofitting has gained much attention with the unveiling of its different applications, such as energy retrofit and deep retrofit, to enhance the climate-resilience of buildings. However, no single study comprehensively assesses the climate-resilience of retrofitting. The purpose of this study is to address this gap via a systematic literature review.

Quality journal studies were selected using the PRISMA method and analysed manually and using scientometrics. Three dimensions of climate-resilience, such as robustness, withstanding and recovery, were used to evaluate the contribution of retrofit measures for achieving climate-resilient houses across four climate zones: tropical, arid, temperate and cold.

Most passive measures can enhance the robustness of residential buildings but cannot verify for withstanding against immediate shocks and timely recovery. However, some passive measures, such as night-time ventilation, show excellent performance over all four climate zones. Active measures such as heating, ventilation and air conditioning and mechanical ventilation with heat recovery, can ensure climate-resilience in all three dimensions in the short-term but contribute to greenhouse gas emissions, further exacerbating the long-term climate. Integrating renewable energy sources can defeat this issue. Thus, all three retrofit strategies should appropriately be adopted together to achieve climate-resilient houses.

Since the research is limited to secondary data, retrofit measures recommended in this research should be further investigated before application.

This review contributes to the knowledge domain of retrofitting by assessing the contribution of different retrofit measures to climate-resilience.

Artificial fruit ripening is hazardous to mankind. In the recent past, artificial fruit ripening is increasing gradually due to its commercial benefits. To discriminate the type of fruit ripening involved at the vendors’ side, there is a great demand for on-sight ethylene detection in a nondestructive manner. Therefore, this study aims to deal with a comparison of various laboratory and portable methods developed so far with high-performance metrics to identify the ethylene detection at fruit ripening site.

This paper focuses on various types of technologies proposed up to date in ethylene detection, fabrication methods and signal conditioning circuits for ethylene detection in parts per million and parts per billion levels. The authors have already developed an infrared (IR) sensor to detect ethylene and also developed a lab-based setup belonging to the electrochemical sensing methods to detect ethylene for the fruit ripening application.

The authors have developed an electrochemical sensor based on multi-walled carbon nanotubes whose performance is relatively higher than the sensors that were previously reported in terms of material, sensitivity and selectivity. For identifying the best sensing technology for optimization of ethylene detection for fruit ripening discrimination process, authors have developed an IR-based ethylene sensor and also semiconducting metal-oxide ethylene sensor which are all compared with literature-based comparable parameters. This review paper mainly focuses on the potential possibilities for developing portable ethylene sensing devices for investigation applications.

The authors have elaborately discussed the new chemical and physical methods of ethylene detection and quantification from their own developed methods and also the key findings of the methods proposed by fellow researchers working on this field. The authors would like to declare that the extensive analysis carried out in this technical survey could be used for developing a cost-effective and high-performance portable ethylene sensing device for fruit ripening and discrimination applications.

Urban mobility has substantially evolved in several western countries, shifting from interest in road expansion strategies to cater motorized movement to the emphasis on sustainable mobility. This is, however, not the case in several developing countries that still try to accommodate vehicular flows in inner historic cities. This paper aims at providing an assessment framework that helps in evaluating the effect of streetscape development on the walking and cycling environment in historic contexts.

This research follows a two-phase methodology. Phase 1 is the investigation of the literature review including the streetscape design, Sustainable Development Goals (SDGs) and indicators for the assessment of walking and cycling environment. This phase results in developing a set of indicators for the assessment. Phase 2 is the case study including, methods, steps and results of the assessment based on the output of Phase 1. This phase concludes with a discussion on the challenges and recommendations for the enhancement.

The streetscape development in Afrang was insufficient and negatively affected the walking and cycling environment. It was motorized-oriented, instead of enhancing green mobility. The interventions led to more crowds, safety risks and less pleasant experience. Moreover, the car users' experience was enhanced initially; however, the traffic situation did not persist. A sustainable urban mobility approach is necessary to be implemented with consideration to the global level and the relation to SDGs.

There is a gap in tackling the research problem both within the context of Port Said in particular and Egyptian context in general. Local authorities need a clear structured methodology to follow in the development of the streetscape. The assessment indicators gathered can be the basis for evaluating future plans.
