    Assessment of low-rise buildings with transfer beam under seismic forces

    No full text
    An overview of the structural performance of a transfer structure in Hong Kong under potential seismic actions is presented. A hypothetical but realistic low-rise building model has been developed comprising a seven-storey reinforced concrete frame structure with reinforced concrete transfer beams at first floor level. Structural design has been based on the British Standard BS8110 and local practices. Parametric analyses of the moment–curvature relationship of each component have been conducted. By adopting the displacement-based (DB) approach, various seismic assessment methodologies, including response spectrum analysis (RSA), manual calculation, pushover analysis (POA) and equivalent static analysis (ESA) have been implemented. The deformations induced by the predicted seismic actions in Hong Kong are compared with those arising from POA in terms of average lateral drift ratios and maximum interstorey drift ratios arising in the building. Factors influencing the performance of this form of transfer structure are highlighted and discussed. This paper also provides a general indication of seismic vulnerability of common low-rise transfer structures in regions of low to moderate seismicity

    Telling stories: a metagame description of a conflict

    No full text
    This paper describes the use of metagame analysis to describe and explore a conflict situation. The analysis was carried out by the author, who was associated with one of the parties in the conflict, for his own benefit. A full description of the analysis is provided. A particular characteristic of the situation was that it was not possible to specify preferences for scenarios for any of the actors with a reasonable degree of confidence. This made the standard metagame analysis approach unworkable, and an alternative approach, involving the development of stories describing a variety of possible future events, was used instead

    In the version of this Article originally published, the sentence ‘D.-S.H. wrote the paper with K.L., J.H. and M.K.’ in the author contributions was incorrect; it should have read ‘D.-S.H. wrote the paper with K.L., J.H., M.-H.J. and M.K.’ This has been corrected in the online versions of the Article
