【 摘 要 】

Based on the quasi-static shock test of a three-storey single-span fabricated prestressed concrete frame, the crack and damage of each node when the test frame is in the ultimate failure state are understood. The crack resistance of each node is calculated and analyzed. The deformation characteristics of the core region of the node are discussed according to the load of displacement and shear angle hysteretic curve, and the nonlinear simulation is carried out with the finite element software ANSYS. The results show that the failure of the fabricated prestressed concrete frame occurs at the end of the beam, while the core area of the joint is not damaged under the condition of two-way stress, which has strong crack resistance and deformation resistance and meets the seismic design requirements of "strong joints and weak components".
