［摘要］通過(guò)對(duì)鋼板剪力墻外包混凝土蓋板來(lái)提高鋼板的抗屈曲能力，形成一種新型組合鋼板剪力墻。為研究此種組合鋼板剪力墻的抗震性能，在一榀組合鋼板剪力墻低周循環(huán)加載試驗(yàn)的基礎(chǔ)上，采用ANSYS軟件建立非線性有限元模型，考慮影響結(jié)構(gòu)抗震性能的5個(gè)主要因素：節(jié)點(diǎn)轉(zhuǎn)動(dòng)剛度、組合鋼板剪力墻螺栓排布、內(nèi)填鋼板厚度、混凝土蓋板數(shù)量及厚度，進(jìn)行了5個(gè)系列15個(gè)有限元模型的變參數(shù)分析。結(jié)果表明：通過(guò)在鋼板剪力墻單側(cè)或雙側(cè)外包混凝土蓋板可有效提升鋼板的抗屈曲能力，增強(qiáng)結(jié)構(gòu)的抗震性能；減少螺栓數(shù)量會(huì)提高結(jié)構(gòu)的變形能力，但會(huì)降低結(jié)構(gòu)的極限承載力和耗能能力；采用半剛性節(jié)點(diǎn)，合理設(shè)置內(nèi)填鋼板厚度和混凝土蓋板厚度有利于結(jié)構(gòu)抗震。［關(guān)鍵詞］組合鋼板剪力墻; 有限元法; 參數(shù)分析; 抗屈曲能力; 抗震性能中圖分類號(hào)：TU398.2,TU311.41 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)15-0076-05
Seismic behavior analysis of semi-rigid steel frame with composite steel plate shear wall structurePeng Xiaotong1, Zhang Qi2, Li Haibin1(1 School of Civil and Architectural Engineering, Jinan University, Jinan 250022, China; 2 Qingdao Yijing Engineering Consultant Co.， Ltd., Qingdao 266003, China)Abstract:A new type of composite steel plate shear wall (CSPSW) was proposed, whose buckling resistance ability of steel plates is enhanced by the covered concrete plates of the steel plate shear wall. In order to study the seismic behavior of CSPSW, the nonlinear FEM models were established by software ANSYS based on the low cyclic loading test of a piece of CSPSW specimen. Parameter analyses of 15 finite element models of 5 series were performed, considering 5 main influential factors of rotational stiffness of connections, configuration pattern of CSPSW bolts, infill steel plates thickness, concrete cover plate number and thickness were considered. The results indicate that the buckling resistance ability of the steel plates is enhanced effectively by one-side or both-sides covered steel plate shear wall with concrete plates, and the seismic behavior of the structure is improved. Reduction of the number of bolts increases the deformation capacity of the structure and reduces the ultimate capacity and energy dissipation capacity of the structure. It's beneficial for the seismic behavior of the structure with adoption of semirigid joint and reasonable set of steel plate thickness and concrete cover plate thickness.Keywords:composite steel plate shear wall; finite element method; parameter analysis; buckling resistance ability; seismic behavior
