| 摘 要： | 目前我们对建筑结构进行连续性倒塌分析时经常参考和借鉴美国GSA规范方法，这种方法中的倒塌评判标准在我国不是很适用。爆炸激励仿真分析方法虽然可以考虑空气冲击波对结构的作用及结构构件的损伤破坏，但是由于计算量过大而很难在实际工程中应用。该文利用简化的爆炸荷载考虑爆炸空气冲击波对结构构件的作用；利用可以考虑应变率效应的非线性...

| Abstract: | At present,General Services Administration(GSA) standard method is widely used for reference to analyze progressive collapse of buildings.However,the criteria of collapse evaluation of this method are found inapplicable in China.Although the loading on structure caused by air shock wave and the damage failure of structural members are considered in explosive incentive simulation analysis method,it is hard to apply in practical engineering due to its computational complexity.In this paper,a simplified progre... |
