灌浆墙体中考虑面板支撑作用抗弯承载力分析

The analysis of the flexural resistance for grouting wall with panel supporting effect

采用有限元分析对面板灌浆墙这一组合墙体形式的抗弯承载能力进行分析,在建立有限元模型时,考虑了面板的支撑作用,并对几个影响因素分别进行分析,确定了一种较合理的模型,结果分析表明:面板对墙体截面的抗弯承载能力有较大幅度的提高,设计时不可忽略,此外填充料、板拼缝等因素都对墙体抗弯承载力也有一定影响。

This paper adopts the finite element method to study the flexural resistance of grouting walls. To build the finite element model, the supporting role of the panel is considered. A reasonable model was determined by analysis of several factors. The results show that the supporting effects of panel has considerable contribution to the flexural capacity, and can not be neglected in design. In addition, filling material and panel gaps have an impact on the wall flexural capacity.
