In order to study the mechanical performance of semi-rigid angle connections of H-beams with corrugated webs, semi-rigid angle connections were simulated under the static loading with the finite element software ANSYS. With different angle thickness and different height of the H-beams with corrugated web, we can obtain the moment-rotation curve and stress cloud pictures, then analyze the influence of the angle thickness and the height of the H-beams with corrugated web to the behaviors of the connections. Results show that increasing the thickness of the angle, the initial rotational stiffness and bending capacity of connections have a growing trend, but the growth rate decreases, When the thickness of the angle increases to a certain extent, the influence is little; Increasing the thickness of the angle, the ductility of the connection will reduce; Increase of beam section height can effectively improve the connection initial rotational stiffness and bending capacity.
