Abstract

Purpose

In recent years, three-dimensional (3D) seismic base isolation system has been studied extensively. This paper aims to propose a new 3D combined isolation bearing (3D-CIB) to mitigate the seismic response in both the horizontal and vertical directions.

Design/methodology/approach

The new 3D-CIB composed of laminated rubber bearing coupled with combined disk spring bearing (CDSB) was proposed. Comprehensive analysis of constitution and theoretical derivation for 3D-CIB were presented. The advantage of CDSB is that the constitution can be flexibly adjusted according to the requirements of the bearing capacity and vertical stiffness. Hence, four different combinations of CDSB were designed for the 3D-CIB and employed to isolate nuclear reactor building. A comparative study of the seismic response in terms of seismic action, acceleration floor response spectra (FRS), peak acceleration and relative displacement response was carried out.

Findings

3D-CIB can effectively reduce seismic action, FRS and peak acceleration response of the superstructure in both the horizontal and vertical directions. Overall, the horizontal isolation effectiveness of 3D-CIB was slightly influenced by vertical stiffness. The decrease in the vertical stiffness of the 3D-CIB can reduce the vertical FRS and shift the peak values to a lower frequency. The vertical peak acceleration decreased with a decrease in the vertical stiffness. The superstructure exhibited a rocking effect during the earthquake, and the decrease in the vertical stiffness may increase the rocking of the superstructure.

Originality/value

Although the advantage of 3D-CIB is that the vertical stiffness can be flexibly adjusted by different constitutions, the vertical stiffness should be designed by properly accounting for the balance between the isolation effectiveness and displacement response. This study of isolation effectiveness can provide the technical basis for the application of 3D-CIB into real engineering of nuclear power plants.

Abstract

Is the nuclear sky falling? It appears so. With the quantitative and qualificative improvements in nuclear stockpile, a proliferation-pessimism finds expression in metaphors about nuclear dominoes, chains etc. With a number of threshold states, the catch-phrase is ‘credible deterrence’. However, much of the zero-sum cold war thinking on strategic defence has now become anachronistic. A phased adaptive approach, leading to universal disarmament is necessary, especially in India’s strategic interest. A nuclear weapon-free world could ensure a safer regional security environment for India. It’s all the more imperative in view of China’s interest to emerge as the strategic leader in Asia, even well beyond Asia.

New START initiatives are positive developments in this regard. However, it is necessary to bring into this fold other nuclear powers. (China has rejected the US and Russian levels of nuclear ‘transparency’ as part of its defence calculus; it has already crossed the multiple warhead Rubicon. It may also install a National Missile Defence System by 2020.)

Though a Nuclear Weapon-Free World (NWFW) cannot emerge instantaneously, an NWFW can evolve, if the following measures are evolved:

  • (i)

    Change the mind-set devaluing nuclear weapons by strategically displacing ‘disbelief’ with ‘faith’ in the efficacy of nuclear abolition.

  • (ii)

    Change the perception of  the utility and prestige associated with nuclear weapons.

  • (iii)

    Redraft nuclear doctrines to restrict their role and break the ‘feed-back paradigm of the need for nuclear deterrence’.

  • (iv)

    Take measures to build confidence in multilateral initiation on NWFW.

  • (v)

    Ensure universal acceptance of ‘no first use’ (NFU) through a legally binding, universally accepted agreement.

  • (vi)

    Have agreement prohibiting the use or threat of use of nuclear weapons.

  • (vii)

    Devise agreements for controlling the continuous qualitative upgradation.

  • (viii)

    Establishment of a Safeguard Regime with thorough organizational and institutional mechanism.

  • (ix)

    Use advanced surveillance and monitoring technology to ensure compliance.

  • (x)

    Implement effective enforcement strategy to penalize delinquent.

It is in India’s interest to pursue universal disarmament with universal focus on economic and social cohesion for war prevention as the key to long-term security.

As the first Asian country to build a nuclear reactor, and as one among the handful of countries with full nuclear fuel cycle capabilities, India should strive to bring about universal disarmament of nuclear weapons so that world can meet spiralling demand for power through nuclear reactors, which pose no threat to the world peace.

Abstract

Top secret tests which are now going on at a factory in Cheshire look like giving Britain a commanding partnership in nuclear development. And if optimism is borne out, industry—particularly in the precision engineering field—can expect rich rewards.

Abstract

Not since the Great Depression of the 1930s have the activities of individual corporations come under as much scrutiny as they have over the past decade. With daily headlines about the savings and loan crisis, insider trading, layoffs and plant closures, green marketing, ingredient labeling practices, and influence‐peddling political contributions, the new watchwords in the business world are ethics, accountability, and social responsibility.

Abstract

Subject area

Human resource management.

Study level/applicability

The case can be used on courses related to human resources management (HRM), which are offered in management programmes like MBA/PGDBM. The case could also be used in management development programmes, seminars and workshops that have HRM as a component of the programme. The case can be used effectively for classroom discussions as well as in distance learning programmes.

Case overview

The case looks into the HRM practices at a leading Indian construction company – ABC Constructions. The case tries to explain the management perspectives behind the people practice initiatives undertaken by the company in order to recruit/retain and nurture talent. The case also explains the basic principles underlying its human resource policies. It tries to explain the initiatives taken by ABC Constructions to meet the challenges posed by the changing business environment, as the company moves beyond the borders of the country of its initial operations. The case provides an overview of unique challenges faced by a company in the Indian construction industry, where a significant number of people executing its projects are not its permanent employees.

Expected learning outcomes

The students would get a fairly good understanding of existing good practices in the field of human resource management, especially in the context of a multifaceted and labour intensive construction industry in the Indian corporate scenario. Anecdotes of actual experiences with respect to people management would facilitate greater understanding of the complexities involved at the grass root level of functioning and implementation. Theoretical inputs relating to training could be better understood through the customised programmes provided by the company for its diverse workforce. The HR challenges faced by the top management as a company grows and expands to new markets can better be understood.
