无腹筋简支开洞深梁受剪性能及强度

Shear Behavior and Strength of the Simply Deep Holed -beam without Web Steel Resisting Concentrated Forces

对集中荷载作用下无腹筋简支开洞深梁提出了上拱下梁的传力模型以及上拱有效高度的概念，并在洞口上下两部分子结构中又分别采用了深梁传力桁架模型．计算结果和试验符合较好．

The concepts of converting force model of upper arch and lower beam,and the effective height with refernce to the simply deep holed-beam without web Steel with concentrated load are given.Truss model converting force of deep beam is taken respectively in the molecule structure of the upper and lower parts of the hole.The calculation results comply basically with the experiment.
