摘要

本文介绍了采用选择位移控制点的弧长法数值计算剪力破坏梁的回弹荷载-挠度关系的方法。在荷载减小时识别应力加载区域,阐明了梁的回跳剪切破坏过程。通过能量平衡计算,将对这种现象的基本认识扩展到结构的破坏概念。

Post-peak Behavior of Shear Failing Beams Governed by Snapback Instability
This paper describes how snapback load-deflection relations of shear failing beams are numerically obtained using Arc Length Method with Selected Displacement Control Points. Identifying stress loading area while load decreases, failure process of snapback shear failure of a beam is clarified in the paper. The fundamental understanding of the phenomena is extended to failure concept of a structure through energy balance calculation.
