Abstract

To study the fatigue performance of bolted connections in timber-concrete composite structures(TCC), this paper adopts a combination of experimental research and theoretical analysis to design 15 push out specimens for static and fatigue tests. The changes in mechanical properties such as fatigue life, residual slip development, shear bearing capacity, and stiffness of bolted connections are obtained. On this basis, the fatigue failure mode is analyzed to provide reference for the fatigue design of TCC.
