| The assembled concrete structure has the advantages of short construction period,high product quality,low energy consumption and low environmental pollution.It is an inevitable choice to realize the industrialization of green building.In practical engineering,the assembled frame structure is widely used.The integrity between prefabricated components in frame structure and reasonable connection structure has a great influence on the seismic.The beam-column joint is the key to the whole assembly type frame structure.Reasonable design and reliable connection technology is the priority among priorities to improve the beam-column joint assembly force performance.In order to study the influence of high strength bolted steel connection on the mechanical properties of the fabricated joint.The paper focuses on the study of the connection of the beam-column connection.In this paper,a full-scale test is carried out to study the seismic behavior of concrete beam-column joint with steel plate bolted connection.By means of MSC.Marc finite element software,this paper establishes the model of steel plate bolted connection of the concrete beam-column joint,and compares the calculated results with the experimental results to verify the rationality of the numerical model.Furthermore,the influence of the thickness and length of the embedded steel on the mechanical properties of the fabricated joint is investigated.In this paper,the experimental study and numerical study on the high strength bolted steel joint of the beam-column joints are carried out to investigate the failure mode and stress behavior of the joint.And flange plate thickness,rib length,rib thickness and other factors were studied on the effect of the mechanical properties of the joint by parameter analysis.At last,according to the failure mode and stress performance of the joint,the design method of the steel plate bolt connection assembling concrete beam-column joint is proposed. |
