Horizontal forces were applied on the summit point of the structure to study the mechanical behaviors of two models under the horizontal forces. Mechanical behaviors of two models were compared such as the internal forces, maximum displacement of summit point, failure mode, structural ultimate bearing capacity and the durability property. Results demonstrate that the ultimate bearing capacity and lateralresistant stiffness of dual coupling beams with slabs are larger than that of the model without slabs, but the displacement durability is relatively lower.Keywords: dual coupling beams with slab; nonlinear finite element; maximum displacement of summit point; internal force*天津市应用基础与前沿技术研究计划(12JCQNJC05300)。作者简介:张海,博士,副教授, Email:zhanghai@tju.edu.cn。参考文献[1]朱炳寅. 对“双连梁”的认识与设计建议[J]. 建筑结构·技术通讯,2008,38(11):12-13.[2]李奎明,孙春毅,李杰. 高性能混凝土双连梁短肢剪力墙试验研究[J].地震工程与工程振动,2006, 26(3):121-123.[3]陈云涛.双连梁的等效分析[J].建筑结构, 2006,36(S1):1040-1043.[4]GB 50010—2010混凝土结构设计规范[S].北京:中国建筑工业出版社,2011.[5]胥玉祥,朱玉华,赵昕,等. 双连梁受力性能研究[J]. 结构工程师,2010,26(3): 31-37.[6]曹杨, 李杰. 双连梁短肢剪力墙结构非线性损伤分析[J]. 同济大学学报: 自然科学版, 2008,35(12): 1587-1591.[7]李杰, 李奎明. 钢筋混凝土短肢剪力墙结构非线性分析研究[J]. 建筑结构学报, 2009, 30(1): 23-30.[8]汪梦甫, 周锡元, 黄立忠. 钢筋混凝土开洞剪力墙结构抗震非线性有限元分析[J]. 地震工程与工程振动, 2005, 25(3): 47-54.[9]皮天祥,刘光伟,傅剑平. 新配筋方案带楼板的双连梁抗震性能对比试验[J].重庆大学学报:自然科学版,2007,30(8):107-113.[10]谷倩,朱飞强. 双连梁与深连梁剪力墙结构抗震性能对比分析[J]. 土木工程学报,2010,43(S1):211-216.[11]孙宏兵. 高性能混凝土双连梁剪力墙结构抗震性能分析[D]. 合肥:合肥工业大学, 2010.
