Abstract

A unique experimental field test study that provides insight into the push-over load-deflection and collapse behaviour of a soft storey building is reported in this paper. The five storey building had been identified as being particularly vulnerable to earthquake excitation due to the particularly weak connections at each end of the ground floor precast columns that constituted the soft storey. Consequently, four field tests were undertaken to investigate the actual lateral force-deflection behaviour of the soft storey columns. Interestingly, the tests indicated that the soft storey columns possessed significant displacement capacity despite significant strength degradation. An analytical mo..
