摘要

本研究利用非線性反應分析，進行鋼筋混凝土建築物之倒塌分析。此倒塌分析，以建築物之支柱，瞬間地被移除，藉以探討樓版垂直向之位移。利用樓版垂直向之位移，進一步建立建築物之易損曲線。此建築物失去垂直向支柱之易損曲線，可以做為防災規劃與風險評估之指標。

並列摘要

The progressive collapse of RC buildings is investigated with a nonlinear analysis. The critical columns are instantaneously removed from the buildings to account for an extreme event destroying the columns. The damage states of buildings are in terms of the vertical displacements of the floor slabs. The fragility curves of loss of critical columns are developed for risk estimation.
