框架柱抗震抗火设计因素分析
|
摘要
在介绍地震火灾危害基础上,分析了钢筋混凝土框架柱地震与火灾引起的破坏形式,论述了同时考虑抗震与抗火的钢筋混凝土框架柱相悖与相符的设计因素及其依据,给出了相悖设计因素的弥补方法。相关结论对需要同时考虑抗震与抗火的钢筋混凝土框架柱的设计具有一定的指导意义。
On the basis of introducing the devastating effects imposed by post-earthquake fire on structures,the damage forms of RC frame columns caused by earthquake and fire are analyzed.The inconsistent design factors and consistent ones and their evidences for RC columns when taking simultaneously both earthquake and fire resistance into account are discussed.Remedy methods in selecting in consistent design factors are provided.This conclusion plays an important guiding role in the design of RC frame column when taking simultaneously both earthquake and fire resistance into account.
