Numerical Model Research on Rotational Performance of Beam-Column High-Strength Bolt Extension End-Plate Connection Node
Abstract
The high-strength \nbolted end plate connection is widely used in the construction industry with \nits green environmental protection and excellent seismic performance. The \njoints of the joints are semi-rigid, the force performance is extremely \ncomplicated, and the experimental research cost is relatively high, and the \ncycle is very long. Therefore, the establishment of an efficient numerical \nmodel is of great significance for evaluating the force performance of \nhigh-strength bolt end plates. In this paper, the influence of different \nmaterial models on the rotation performance of the joint is studied by \nnumerical simulation, and the bending moment-rotation curve is obtained. The \nnumerical simulation and the experimental results are in good agreement, so as \nto provide a reference for the design and application of this kind of joint.
