The Influence of Slab on Yield Mechanism of RC Frame Structure

Abstract:

"Strong column weak beam" form of frame structure is widely considered to be a reasonable framework structure yield mechanism in the seismic damage. The current structure design is mostly on the basis of that yield mechanism for structural seismic design. Generally the structural engineers ignore the bearing capacity contribution of frame beams that comes from the slab in the seismic design. The structure engineers considered the slab as a rigid component and simply calculate the slab stiffness by magnification factor method, which ignores the core of the problem. This paper analyzes mainly the influence of the destruction of slab form frame structure , studying further how slab affect the yield mechanism of frame structure, and explores the destruction form of difference between two models after analyzing two structure models by the method of Push – over. It shows that the existence of slab make the yield mechanism of RC frame structures different from the design.
