The main contents are as follows. By the experiments of two joints under low-reversed cyclic loading, the paper analyzes the failure pattern, energy dissipation, ductility and cracking in the joint cores, evaluates the seismic performances and anti-crack behaviors of the joints, and deduces the anti-crack formula of the subassemblage and prestressed frame joint. Through the finite element analysis software Ansys , the paper analyzes the specimens nonlinearly, and the theoretical analysis results are well consistent with those of the experiment.
