针对RC框架结构梁板柱空间协同工作效应的非线性仿真分析问题,提出了建立在三维实体退化虚拟层合单元理论基础上同时考虑结构双重非线性的空间分析计算方法;先利用该方法及其程序对一RC空间框架单柱失效倒塌试验含其梁板柱空间协同工作效应进行了全过程分析,所得结果与试验实测吻合良好。据此,再以一典型的两层钢筋混凝土框架结构为例,给出了考虑梁板柱协同工作的结构空间效应和空间破坏形态的计算分析结果。分析研究表明,为考虑梁板柱空间协同工作效应的RC框架结构非线性仿真分析提供了一种合理有效的途径,计算方法具有很好的适用性。

英文摘要：

For non-linear simulation analysis on spatial coordinated interaction of beam-slab-column of RC frame structure,a spatial analysis method based on degenerated three-dimensional solid virtual laminate el- ement theory while taking into account the dual none-linearity of structure was presented. By using this method and its program,the collapse test of RC space framework with an invalid column and the space co- ordination interaction among beam-slab-column were simulated, which is in good agreement with theoreti- cal analysis. Furthermore,taking the two layer RC frame structure as an example and considering the spa- tial coordinated interaction of beam-slab-column, the calculation and analysis results on the spatial effect and spatial failure modality of the structure were presented, thus providing a reasonable and effective way to non-linear simulation analysis on spatial coordinated interaction of beam-slab-column of RC frame struc- ture. The above method has excellent applicability.
