考虑连续倒塌的大型建筑物结构毁伤评估

Structure Damage Assessment of Large Building Considering Progressive Collapse

针对大型建筑类目标快速、准确毁伤评估需求,提出基于构件贡献因子的考虑连续倒塌因素的目标结构毁伤评估方法。通过分析目标结构毁伤机理,计算关键构件贡献因子并建立其毁伤准则等流程,进而构建目标结构毁伤计算模型。仿真结果表明,该方法能够快速、准确实现目标易损性分析与毁伤评估。

Aimed at the demand for rapid and accurate damage assessment of large building targets,a damage assessment method of building structures considering progressive collapse factors based on compo⁃nent contribution factors is proposed.The damage calculation model of the target structure is built by the analysis of damage mechanism of target structure,the calculation of component contribution factors and set⁃ting up the damage criterion and other processes.The simulation results indicated that the target vulnerabil⁃ity analysis and damage assessment can be quickly and accurately realized by the proposed method.
