Abstract

Abstract

To study the deformation mechanism of prefabricated steel frame beam-column joints and clarify the cause of joint rotation deformation, the calculation method of rotation deformation of beam-column joints with extended end-plate connections was theoretically deduced based on component method, and the joint specimens were tested under quasi-static loading. The deformation of joints during loading test was analyzed by image processing method, and the equivalent simplified numerical model of the joint specimens with extended end-plate connection was established. The results showed that the rotational deformation of the extended end-plate joint consists of shear deformation in the panel zone, relative deformation between end-plate and column flange, and yield deformation of end-plate stiffener, among which the relative deformation between end-plate and column flange and yield deformation of end-plate stiffener were the main factors affecting the joint rotation angle. Compared with the traditional processing method, considering the influence of multiple components on the deformation of the joint in the rotating spring could make the numerical simulation results closer to the test results, which was beneficial to evaluate the seismic performance of the joint. The calculation method of joint rotation angle showed good accuracy and applicability for predicting the seismic performance of joints.
