摘要


本研究主要探討空間架構多柱移除之易損性分析,以一棟九層樓之抗彎矩剛構架之鋼結構建築物為案例探討。柱子移除位於不同的樓層,內外柱之移除,斜撐之影響均亦納入分析考慮,並以非線性歷時反應進行分析。不同柱子移除之風險,以最大似然法,藉以建立相對應之易損曲線。此易損曲線可以應用於既有興新建空間架構建築物之風險評估,以利防災之規劃之用。

並列摘要


The fragility curves of space frames with multi-column loss are constructed in this research. A nine-story steel frame building having different column-loss scenarios is investigated. The loss of columns on the different stories, interior columns and exterior columns, with and without bracing is conducted with a rigorous time history analysis. The corresponding fragility curves of various column-loss scenarios are achieved with the maximum likelihood method. The fragility curves can be implemented to hazard reduction planning in the existing and new construction buildings for safety evaluation.
