This paper presents results of analytical evaluation conducted on beam-column connection using nonlinear static pushover analysis (NSPA) process. The aim of using this technique is to investigate the efficiency of the configuration used in conventional steel beam-column connections. In this research work the beam was subjected to two different applied loads; which are concentrated load and uniform distributed load. Two case scenarios have been studied to check the stability of connections while distributed load increased by a factor of 2. The beam is connected to the column by a fully penetration weld. Numerous correlations have been investigated such as base shear vs. displacement, displacement vs. time, and base shear vs. time. The numerical result indicated that joint capacity for both cases show the same behavior in the elastic range.However its behavior changes in the plastic range.The results showed that with increasing (doubled) the applied load on the beam-column connection the base shear and peak displacement do not change. Moreover, for studying the yield point of welded beam-column connection, the model analysis “finite element modeling (FEM) software” was conducted.
