9、2.9框架梁柱内力组合

1、2 上部结构设计2.9框架梁柱内力组合（1）（永久荷载和可变荷载均相同）考虑竖向荷载作用下梁端出现塑性铰，产生塑性内力重分布。因此对梁端支座负弯矩乘以调辐系数 予以降低，本结构为全现浇框架结构，调幅系数取0.85。而为了将调低的弯矩加到跨中中去，跨中弯矩乘以1.2增大系数。梁端弯矩计算及内力调整结果见表表1竖向永久荷载作用下的AB跨梁内力调整调整前调整后层号MABMOMBAMABMOMBA4-66.3366.84-107.51-56.38 80.21 -91.38 3-63.6031.22-73.00-54.06 37.46 -62.05 2-59.9233.54-72.05-50.93 40
