1、河南科技大学毕业设计第7章 框架结构的内力组合7.1框架结构梁内力组合7.1.1. 框架结构梁的内力组合在竖向荷载作用下,可以考虑梁端塑性变形内力重分布而对梁端负弯距进行调幅,调幅系数为现浇框架:0.8-0.9,本设计取0.85。计算结果见表7-1 横梁弯矩调幅。由于风荷载作用下的组合与考虑地震组合相比,一般较小,对于结构设计不起控制作用,故不考虑。只考虑以下三种组合形式:一.由可变荷载效应控制的组合: 二.由永久荷载效应控制的组合: 三.竖向荷载与水平地震作用下的组合: 具体组合过程见表7.2,其中弯矩KN.m,剪力KN,弯矩的上部受拉为负,剪力的产生顺时针为正。101表7-1 横梁弯矩调幅
