［摘要］基于豎向構(gòu)件軸壓比的物理本質(zhì)，對各規(guī)范中相關(guān)軸壓比的條文進行比較與討論。建議規(guī)定特一級抗震豎向構(gòu)件的軸壓比，剪力墻宜按全墻高控制軸壓比，剪力墻底部加強區(qū)與非底部加強區(qū)的軸壓比限值應有所不同，且二級抗震與三級抗震剪力墻的軸壓比限值也應有所不同。對鋼筋混凝土剪力墻、型鋼混凝土柱、型鋼混凝土剪力墻、鋼板混凝土剪力墻的軸壓比限值及其計算方法給出了建議。［關(guān)鍵詞］軸壓比; 鋼筋混凝土剪力墻; 型鋼混凝土柱; 型鋼混凝土剪力墻; 鋼板混凝土剪力墻中圖分類號：TU318.1 文獻標識碼：A 文章編號：1002-848X(2015)14-0013-06
Control of axial compression ratio of reinforced concrete shear wall and composite structure membersHan Jianqiang, Li Li, Wang Yigong, Wang Weiming(Guangzhou Design Institute, Guangzhou 510620, China)Abstract: The provisions about axial compression ratio in different codes were compared and discussed based on the physical essence of axial compression ratio for vertical members. It was recommended that the axial compression ratio of vertical members of special first-level seismic grade should be provided, that the axial compression ratio of the shear wall should be controlled along the whole wall height, that the limited values of bottom strengthening zone and other zones of the shear wall should be different, and that the limited values of shear wall with second-level and third-level seismic grades should be different. Recommendations on limit values and calculating method of axial compression ratio for reinforced concrete shear wall, steel reinforced concrete column, steel reinforced concrete shear wall and steel plate concrete shear wall were given.Keywords: axial compression ratio; reinforced concrete shear wall; steel reinforced concrete column; steel reinforced concrete shear wall; steel plate concrete shear wall
