摘要:建筑结构连续倒塌,是一类由偶然作用引起,可能造成重大生命财产损失的结构安全事故。针对建筑结构连续倒塌的数值模拟问题,本文分析了结构倒塌过程中面临的力学计算难点,对比研究了常用的数值模拟方法,并介绍了作者提出的质点元法。
Abstract: Progressive collapse of building structure which may lead to great damage usually occurs under the extreme events. Considering the nonlinear dynamic simulation of building progressive collapse, the difficulties of computational mechanics were studied.Then the advantages and disadvantages of normal numerical methods to simulate the process of building progressive collapse were compared. Finally, the particle element method was introduced.
