Experimental Research on Seismic Capacity of the Frame Sandwich Boundary Joint

Abstract:

In the tall building frame structure, the traditional frame joints which are usually constructed with the high strength concrete of the columns bring many difficulties to the construction. The frame joints concreted with beams low grade concrete (named as sandwich joint) is urged intensively by the engineers. The paper introduces the experiment of two full-scale sandwich boundary joints in the middle floor under cyclic load. Based on the test result, the specimens seismic behavior on performance of load-carrying capacity, node deformation, ductility, energy dissipation capacity etc are studied. Through comparison with traditional frame boundary joints, comprehensive seismic performance of sandwich boundary joints does not significantly reduce. The engineering applications of these sandwich frame joints are proved to be feasible, and some suggestions for the engineering application of this joint are proposed.
