Abstract
At present, there are many tests on the joints of reinforced concrete frame beams and columns, and the corresponding measures have been taken to ensure the strength and ductility of the joints. In this paper, the nonlinear finite element analysis of reinforced concrete beams and reinforced concrete frame beam column joints is carried out from the simple to complex principles. The method of analysis and study of beam column joints with finite element method is discussed, and the force performance of beam column joints is analyzed and studied. This paper briefly introduces the characteristics, research status and development trend of reinforced concrete structure, the significance of research on the force performance of joints and the research progress at home and abroad. According to the characteristics of prefabricated steel frame structure system and how to deal with the connection of beam column joints in design, four kinds of form of bolted end plate connection beam column joints are put forward for on-site construction. The finite element method is used to analyze the stiffness, strength and bolt tension distribution of the beam column joints of each structure.
