［摘要］純框架結(jié)構(gòu)的整體側(cè)向剛度較小，在強(qiáng)烈地震作用下側(cè)向變形大，易造成結(jié)構(gòu)整體倒塌破壞。從增加結(jié)構(gòu)整體冗余度的角度出發(fā)，考慮添加少量鋼筋混凝土剪力墻來提高框架結(jié)構(gòu)的整體抗倒塌能力。并對添加少量剪力墻的各種布置方式及數(shù)量進(jìn)行分析比較，得出可行的平面布置形式及其對框架結(jié)構(gòu)變形形態(tài)的影響。分析增設(shè)少量剪力墻在多遇地震作用下對框架結(jié)構(gòu)彈性層間位移角的改善情況，在此基礎(chǔ)上，進(jìn)一步得出承擔(dān)不同傾覆力矩比例的墻體與彈性層間位移角的對應(yīng)關(guān)系。
［關(guān)鍵詞］剪力墻；框架結(jié)構(gòu)；彈性；變形；彈性層間位移角

Abstract:The overall lateral stiffness of pure frame structure is relatively small, so the lateral deformation is large under the strong earthquake and this could easily lead to overall collapse. For enhancing the redundancy of the overall structure, a few of reinforced concrete shear walls were arranged to improve the whole resisting collapse capability of frame structure. Various kinds of shear walls disposal modes and amounts were analyzed. The feasible disposal modes and the influence of different amounts and modes of walls on the deformed shape of frame structure were obtained. The improving of elastic inter-story drift angle of frame structure under multiple earthquake through adding few shear walls was verified. Moreover, the corresponding relation between walls which bear different capsizing moment ratio and elastic inter-story drift angle was analyzed.
Keywords:shear wall; frame structure; elasticity; deformation; elastic inter-story drift angle
