The effect of ten past earthquake records on the rehabilitation of a 3-storey double unit tunnel form building subjected to in-plane lateral cyclic loading

Abstract

Tunnel form building is frequently utilised by contractors and developers in constructing high rise building due to its rapid construction process and cost-effective method. However, the capability to cater earthquake load is still questionable. In Malaysia, most of the existing buildings were constructed using BS8110 without any provision to earthquake load. Thus, it is vital to investigate the behaviour of these buildings under the influence of multi-level earthquake records. A 3-storey double unit tunnel form building was designed and constructed using BS 8110 to represent the existing residential apartment in Malaysia. Ten past earthquakes ground motion records of minor, moderate, strong, and great were utilised to determine the effect on the 3-storey double unit tunnel form building using fragility curve and capacity-demand response spectrum. From the analysis, the building experienced an extensive damage when subjected to great ground motion, while minor to moderate damages when subjected to moderate and strong ground motion. However, this building survives under the influenced of local minor ground motions. produced.
