Abstract
In steel structures, connections play an important role in the behavior of the structure. In this article, by using numerical modeling with Abaqus finite element software, several different models of beam to steel column connection have been modeled and investigated. This article has investigated the effect of beam-to-column connection with two types of shield and corner connection. Hence, 20 models with different conditions of different thicknesses and different types of hardeners, as well as 6 models with columns filled with concrete, have been investigated and studied. Abaqus finite element software is used for modeling and cyclic load is used for loading. The results show that the model with the shield stiffener had a higher capacity and compared to the corner stiffener, it had a 12-28% higher bending capacity in the connection. By increasing the thickness of the corner or shield of the beam to the column connection, the capacity has increased by about 12 to 25%, in the thickness of 18 mm, the anchor capacity has increased by 12%, and in the thickness of 20 mm, it has been observed to increase by 25%. The column model filled with concrete has a difference of 15-25% compared to the similar model without concrete, and the column model filled with concrete has a higher bearing capacity.
