摘要
含有大开洞的带肋组合钢板剪力墙是在加劲钢板剪力墙与内置钢板钢筋混凝土组合剪力墙的理论研究与工程应用基础上提出的一种新型抗侧力体系。对此类钢板剪力墙的受力机理进行了研究,针对3种典型开洞形式——中部开洞、底部开洞和角部开洞,利用通用有限元软件ANSYS对内部为大开洞带有加劲肋的钢墙板、外部带有钢边框的此类墙板构件进行了弹性与弹塑性受力分析。得到了此类墙板构件的水平荷载-位移曲线,对其刚度、承载力以及在不同受力阶段的力学性能进行了研究。结果表明不同的开洞形式、外包混凝土、洞边肋以及钢板加劲肋是影响此类钢板剪力墙力学性能的主要因素。结合节点有限元分析,介绍了此类钢板剪力墙在某观演建筑中的应用,对其设计要点进行了总结与建议。
The ribbed composite steel plate shear wall with large opening is a new-style lateral resistance system,which is based on the study and application of the stiffened steel plate shear wall and the steel plate reinforced concrete shear wall.The mechanical behaviors of such steel plate shear walls are studied.By utilizing ANSYS software,the elastic and elasto-plastic analysis of the shear wall panels with steel frame and stiffened steel plate is carried out.The stiffness,bearing capacity and mechanical features of the shear wall panels with central opening,bottom opening and corner opening respectively are studied under different load levels.And the lateral load-displacement curves are obtained.Result shows that the type of the opening,the enclosing concrete and the stiffeners are main factors governing the mechanical behavior of this type of steel plate shear wall.The ribbed composite steel plate shear wall with large opening is employed in a building,and its application is illustrated through the FEM analysis.The key points of the shear wall design are summarized and some suggestions are proposed.
