ABSTRACT: The high-strength
bolted end plate connection is widely used in the construction industry with
its green environmental protection and excellent seismic performance. The
joints of the joints are semi-rigid, the force performance is extremely
complicated, and the experimental research cost is relatively high, and the
cycle is very long. Therefore, the establishment of an efficient numerical
model is of great significance for evaluating the force performance of
high-strength bolt end plates. In this paper, the influence of different
material models on the rotation performance of the joint is studied by
numerical simulation, and the bending moment-rotation curve is obtained. The
numerical simulation and the experimental results are in good agreement, so as
to provide a reference for the design and application of this kind of joint.
