粮食平房仓组合砖墙平面外偏心受压裂缝分析

Out-of-plane Eccentric Compression Analysis of Composite Brick Walls in a Grain Storehouse

砌体结构类型的粮食平房仓,堆高6m时墙体可以采用带构造柱组合砖墙,墙体为平面外大偏心受压构件;现将堆高增加到8m,采用有限元软件模拟分析墙体开裂情况,分析结果表明:墙体内侧在底部容易形成裂缝,影响储粮品质和安全本文通过裂缝分析为堆高较大平房仓的设计选型提供参考。

Composite masonry brick wall with stmctural columns is selected for the grain storehouse design.When grain pile height is up to 6 m,the wall can be constructed with a composite brick wall with structural columns,and the wall can be designed as compression member with large out-of-plane eccentricity.In this paper,finite element method is applied to analyze the wall crack when the grain pile height is increased to 8 m.The analysis results show that the wall interior is easy to have cracks at the bottom.Those cracks have a great effect on the quality and safety of the stored grain.This study provides a reference for the selection of structural types of grain storehouses with high grain storage.
