Seismic Resistance of Composite Coupled Structural Walls

本项目研究钢筋混凝土墙与钢梁耦合的循环性能。关于这种复合结构的信息很少，而这种结构在美国的地震带得到了越来越多的应用。本项目的研究内容包括组合耦合墙的设计、施工、试验测试和分析研究，即钢筋混凝土墙与结构钢梁的耦合。代表一半钢筋混凝土墙墩、一半钢连接梁和部分楼板的子组合的隔离连接将承受模拟地震效应的循环横向荷载。轴向荷载对边界单元、楼板和横向荷载强度的影响将是主要变量。该研究将导致该组合结构体系的设计指南的建立。

This project studies the cyclic behavior of reinforced concrete walls coupled with steel beams. Little information is available about such composite constructions which have seen increased application in the nation's seismic zones. The research undertaken in this project involves design, construction, experimental testing, and analytical study of composite coupled walls, i.e. reinforced concrete walls coupled by structural steel beams. Isolated connections representing a subassemblage of one-half of a reinforced concrete wall pier, one-half of a steel coupling beam,and part of floor slab will be subjected to cyclic lateral loads simulating earthquake effects. Effects of axial load on the boundary element, floor slab, and the lateral load intensity will be the primary variables. The study will lead to the establishment of design guidelines for this composite structural system.
