Research Review on the Connection Joints of Concrete-Filled Steel Tubular Column,Steel Reinforced Concrete Column and Steel Column-Reinforced Concrete Beam
Steel-concrete composite structure does not only have both advantages of reinforce concrete structure and steel structure,but also has the advantages of high bearing capacity,high stiffness,good ductility and seismic performance and material saving,which is in accordance with the future development of civil engineering.The beam-column joint zone is in a complicated space stress condition,and is the important topic in structural design,which is an important foundation for the whole structural safety and reliability and the weak links for the structural seismic design.Therefore,the design of the beam-column joint is critical.Based on the comprehensive research on the connection joint of concrete-filled steel tubular column,steel reinforced concrete column and steel column-reinforced concrete beam,the research status on structural configuration and mechanical properties for the joint are analyzed,and the problems to be resolved of the connection joint for connection method and mechanical properties are put forward,which can provide a theoretical reference for the in-depth study and configurations in this area.
