六层框架抗爆竖向连续性倒塌有限元数值分析

Finite element analysis of vertical continuous collapse of six-story building with anti-blast frame structure

采用大型通用有限元软件ADINA,对我国设计规范条件下钢筋混凝土框架结构的抗爆竖向连续性倒塌进行了数值分析,初步得出了现行设计规范条件下我国框架结构爆炸作用下倒塌时的应力、挠度及相关参数的特点,为更进一步研究结构倒塌的机理、抗倒塌方法打下铺垫。

Utilizing finite element software-ADINA and according to the present design code numerical analysis is carried out to study the vertical continuous collapse of six-story building with anti-blast reinforced concrete structure. The collapse stress and flexibility of frame structure under blast action obtained, which meet current design code and can provide references for further study on collapse mechanism and anti-blasting measures.
