(中国矿业大学建筑工程学院,徐州 221008)[摘要]通过总结短肢钢筋混凝土剪力墙和钢板剪力墙的优缺点和选型参数,将两者相结合,提出短肢钢板剪力墙结构体系。利用ANSYS有限元分析软件对短肢钢板剪力墙的选型参数,即宽长比、单肢钢板剪力墙的高宽比和宽厚比,进行了数值模拟分析。结果表明,提出的短肢钢板剪力墙构造形式及设置参数是可行的,能为结构提供必要的抗侧刚度,并能充分发挥钢板材料塑性,实现耗能目的。[关键词]短肢钢板剪力墙;宽长比;高宽比;宽厚比Study on selection parameters of short pier steel plate shear wallsGuo Zhen, Yuan Yingshu(College of Civil Engineering, China University of Mining and Technology, Xuzhou 221008, China)Abstract:Through the study on short pier reinforced concrete shear walls and steel plate shear walls, short pier steel plate shear walls structure system is presented. Using finite element analysis,the numerical simulation analysis on the selection parameters of short pier steel plate shear walls,such as width-length ratio of steel plate and structure, height-width ratio and width-thickness ratio of steel plate is performed. The results show that the proposed short pier steel plate shear walls and the set parameters are feasible. The lateral stiffness of structure system is enhanced by the form and the plastic of steel is fully exerted.Keywords:short pier steel plate shear walls; width-length ratio; height-width ratio; widththickness ratio*中国矿业大学青年科研基金项目(2008A009)。作者简介:郭震,讲师,博士研究生,Email:guozhen@cumt.edu.cn。参考文献[1]郭彦林, 董全利. 钢板剪力墙的发展与研究现状[J]. 钢结构,2005, 20(1): 1-6.[2]王敏, 曹万林, 张建伟. 组合剪力墙的抗震研究与发展[J]. 地震工程与工程振动,2007,27(5):80-87.[3]缪友武. 两侧开缝钢板剪力墙结构性能研究[D]. 北京:清华大学, 2004.[4]ASTANEH-ASL A.
