第七章 内力组合和最不利内力确定

7.1框架梁内力组合：
1、基本组合公式：
1）梁端负弯矩组合公式:
①-1.0[1.2恒+1.4×0.9(活+风)]
②-1.0[1.35恒+1.4×(0.7活+0.6风)]
③-0.75[1.2(恒+0.5活)+1.3地]
2）梁端正弯矩组合公式:
④0.75[1.3地-1.0(恒+0.5活)]
3）梁跨中正弯矩组合公式:
⑤ 1.0[1.2恒+1.4×0.9(活+风)]
⑥ 1.0[1.35恒+1.4(0.7活+0.6风)]
⑦0.75[1.2(恒+0.5活)+1.3地]
4)梁端剪力组合公式:
⑧1.0[1.2恒0.9×1.4(风+活)]
⑨1.0[1.35恒+1.4(0.7活+0.6风)]
⑩0.85[1.2(恒+0.5活)+1.3地]
7.2框架柱内力组合
采取以下组合方式
考虑地震作用时： ① 1.3×地+1.2×(恒+0.5×活)
不考虑地震作用时：②γ0(1.35×恒+0.7×1.4×活)
③γ0[1.2×恒+1.4×0.9（风+活)]
