（1 上海交通大学土木工程系，上海 200240; 2 上海核工程研究设计院，上海 200240）［摘要］从单元和构件两个层次研究了钢板-混凝土（SC）组合墙的平面内受力行为。在单元层次上，基于已有SC组合墙单元平面主内力空间屈服面，推导了SC组合墙单元的压（拉）剪承载力计算模型；在构件层次上，利用ABAQUS有限元软件，研究了SC组合墙构件在平面内轴向力、剪力及弯矩复合作用下的受力性能，得到剪跨比、轴压比、钢板厚度及混凝土厚度等关键参数对其平面内受力性能的影响，并利用推导的压（拉）剪承载力计算模型对计算结果进行了分析。［关键词］单元; 构件; 钢板-混凝土组合墙; 侧向承载力; 剪跨比; 轴压比中图分类号：TU398.2 文献标识码：A 文章编号：1002-848X(2015)05-0069-06Study on in-plan mechanical behavior of steel-concrete composite wallWang Hailin1, Song Xiaobing1, Ge Honghui2, Chu Meng2（1 Department of Civil Engineering, Shanghai Jiao Tong University, Shanghai 200240, China; 2 Shanghai Nuclear Engineering Research and Design Institute, Shanghai 200240, China）Abstract: The in-plan mechanical behavior of steel-concrete composite (SC) wall was investigated in two levels of element and member. In the element level, based on the existing yield surface for SC wall elements in principle force space, the calculation model of combined axial load and shear capacity of SC wall elements were proposed. In the member level, ABAQUS finite element software models were used to study on the mechanical behavior of SC wall members subjected to in-plan forces as axial force, shear force and moment. As a result, the effects of key parameters such as shear-span ratio, axial compression ratio, steel plate thickness and concrete thickness on in-plan mechanical behavior of SC wall were concluded. The FEM results were analyzed using the built calculation model of combined axial load and shear capacity.Keywords: element; member; steel-concrete composite wall; lateral load capacity; shear-span ratio; axial compression ratio作者简介：王海霖，硕士研究生，Email:wanghailin509@163.com。参考文献［1］冷予冰, 宋晓冰, 葛鸿辉, 等. 钢板-混凝土组合墙体结构平面外抗剪承载力试验研究［J］. 建筑结构，2013，43(22): 15-21.［2］CHU M, SONG X B, GE H H.
