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:
⑤1.0[1.2恒+1.4×0.9（活+风）]
⑥1.0[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：
①1.3×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）]
