| 中文摘要: |
| 近年来，随着倒塌事故的频繁发生，结构的抗连续倒塌问题已经成为严重影响公共安全的重要问题。本文参考DOD2009提供的流程，采用拆除构件法研究了两栋不同布置形式的15层RC框剪结构（分别考虑扭转作用和不考虑扭转作用），并基于有限元软件MIDAS/Gen对其进行了非线性静力分析，通过塑性铰的发展过程及拆柱前后内力对比来分析规则结构和不规则结构的抗连续倒塌性能。 |
| 英文摘要: |
| Recently, with the frequent occurrence of collapse incidents, the progressive collapse resistance of structures has been an important matter which could influence public safety greatly. In this article, dismantling component methodis has been to adopted to study the 15 story RC frame-shear wall structure in two buildings (with or without torsional action taken into consideration respectively) by referencing the flows provided by DOD2009.. And the nonlinear static analysis is conducted to the two modelsbased on the finite element software MIDAS/GenThen, the progressive collapse resistance performance of regular structure and irregular structureis analyzed by the development process of plastic hingesand the inner force comparison before and after the columns dismantlement basing on finite element software MIDAS/Gen. |
