| Abstract: | In this paper, the ANSYS computational model for node of beam and column end-plate with door frame semi-rigid end- plate connections is analyzed, whereby a relationship between the rotation angle and temperature is obtained. Also the critical temperature for extreme rotation angle is achieved. The results provide an economic and feasible method for the analysis of node performance. It is found that during the ANSYS model calculations, use of EC3 high temperature properties of steel is more reasonable. |
