摘要
在加筋壁板剪切稳定性研究中,壁板试件4个边角处细节的构型对剪切破坏强度影响很大。本文分析了3种典型细节的加筋壁板稳定性强度试验数据,并使用有限元方法进行了静力分析。结果表明,直角细节设计方式在受压侧顶点处产生较大应力集中,导致试验件过早破坏,建议采用圆角或钝角进行细节设计。
In the investigation on shearing stability of the rectangle stiffened panel,the corners of a specimen have notable effect on its structural strength.In this paper,3kinds of corner details are investigated by test and finite element analysis,and the result shows that the right-angle-corner specimens are collapsing without buckling for great stress concentration.The curved and obtuse corner is proposed for the corner detail＇s shape.
