摘要

本文在钢筋混凝土均载简支配箍梁抗剪强度计算中引入跨高比后

推导出了两个抗剪强度计算式

使抗剪受力概念与强度计算式相一致

从而使新规范抗剪强度计算式更臻完善.本文二式具有自动调强(自动调整梁截面抗剪强度)之功能

且形式简单

使用方便

几乎不增加计算工作量.在常用跨高比范围内能节约箍筋用量10%左右.

Abstract

By introducing the span-to-height ratio

this paper deduces wo evaluating equations of shear strength of simple reinforced concrete beamwith stirrups and under uniform loads.This makes the shear stressing concept consistent with the evaluating equations

thus improves the evaluating equationsof shear strength of the New Code.Two equations are provided with auto-regulating function on shear strength for a cross section of beam.They aresimple and convenient in evaluation.The working time used for design is not increased and 10% of stirrups is economized in frequent conditions of span-to-height ratio.
