Experimental Study on Seismic Behavior of Mortise-Tenon Joints of Ancient Architectures

Five mortise-tenon joints models made with the requirements of the Gongcheng Zuofa of Qing Dynasty were tested by low-cyclic reversed loading.The behaviors of mortise-tenon joints models,such as the failure forms,hysteretic curves and deformations are analyzed.The test results indicate that the mortise-tenon joints models exhibit good deformation behavior,and the vertical displacement is 100 mm.The separation between mortise and tenon leads to the destruction of the mortise-tenon joints models,squeeze deformation occurs in mortise and tenon,and the beams and columns are intact.The shape of hysteretic hoops of each mortise-tenon joints models is a Z,which proves the properties of the semi-rigid connection of the mortise-tenon joints.
