摘要

密肋壁板结构中多种材料及构件的使用与嵌套,使实体计算模型比较复杂,故对于整体结构在地震动作用下的全过程受力分析,需提出结构的弹塑性简化计算模型。根据不同的分析目的,结合课题组前期研究成果,提出密肋壁板结构在弹塑阶段两种简化计算模型——刚架—等效斜压杆模型和刚架—整体斜撑模型。利用前期墙体拟动力试验研究结果,采用刚架—等效斜压杆模型对结构进行推覆及动力反应分析,验证模型的正确性;利用前期1/10比例振动台试验研究结果,采用刚架—整体斜撑模型对结构进行时程分析,验证刚架—整体斜撑模型的正确性。理论与试验表明:刚架—斜压杆模型具有一定的计算精度与实用性,适用于密肋复合墙体的非线性数值分析;刚架—整体斜撑模型兼顾高效性与精确性,适用于整体结构在大震下的弹塑性时程反应分析。

Abstract

The multi-ribbed slab structure consists of various materials and components nesting each other, which makes the entities calculation model of the structure extremely complicated. Therefore, it is necessary to present the elasto-plastic model for the whole stressing process of structure under strong seismic action. According to different analysis aims, the rigid frame-equivalent diagonal strut model and the rigid frame-whole bracing model of the eco-composite wall structure in elastic-plastic stage are presented. According to the previous results of pseudo-dynamic test on the walls, the rigid frame -equivalent diagonal strut model is employed to perform push-over and dynamic response analysis , therefore, the validity of the model is verified. Based on the previous results of 1 / 10 ratio of shaking table test, the rigid frame-whole bracing mode is employed to perform the time-history analysis, therefore, the validity of the model is verified. Theoretical researches and experimental analysis show that the rigid frame -equivalent diagonal strut model characterized by calculation accuracy and practicability is suitable for nonlinear analysis of multi-ribbed composite wall. The rigid frame-whole bracing mode giving consideration to accuracy and efficiency is applicable to structural elastic-plastic time-history analysis under strong seismic action.
