Investigation and analysis of stress distribution in mixed connections ofconcrete column and steel beam of different reduced sections usingAbaqus software

Conducting tests to check the behavior of structures has a high cost, due to the high costof these tests and the need for many facilities, some of them can be replaced by numericalmethods. In this research, by using the powerful Abaqus software, the performance ofconnections with reduced steel beam and concrete column is investigated, what is desiredfrom the results of the study of the models analyzed in the finite element software, therelationship between the anchor The input in the connection and the rotation resultingfrom it. The analyzed models are also examined in terms of stress distribution, changes inthe input spring of the connection and ductility. The analysis and investigation of thementioned connections have many relative advantages, including the lower weight of thestructure in large spans, more malleability and energy absorption than concrete structures,easier achievement of the criterion of strong column and weak beam, and increasing thespeed of construction. He pointed to concrete structures. One of the most important partsof various steel beam and concrete column structures is its connections. To control theaccuracy of the modeling method in this research, the experimental results of three steel,integrated and mixed concrete connections of steel beam to concrete column have beenused.
