Experimental study on seismic performance of full-scale inorganic adhesive composite bamboo beam-column connections
摘要
Abstract
Based on the engineering demand for the seismic safety design of beam-column connections in a certain five-story inorganic adhesive composite bamboo frame-bracing structure,two full-scale inorganic adhesive composite bamboo beam-column connections were designed and fabricated,and low-cycle reversed loading tests were conducted to clarify the influence of beam-end interface adhesive injection on the load-resisting mechanism and seismic performance of the connections.The seismic performance and failure mechanisms of the full-scale steel connector-bolt connection and the steel connector-bolt-adhesive hybrid beam-column connection were comparatively investigated.The results show that the interface-unbonded connection is mainly characterized by local crushing and splitting parallel to the grain of inorganic adhesive composite bamboo at the beam end.The hysteretic curves exhibit an evident inverse S-shape,and due to the unidirectional restraint of the steel bearing plate at the beam bottom,the ultimate bending moments in the push and pull directions differ by approximately 23.9％,indicating pronounced asymmetry and pinching behavior.For the interface-bonded connection,adhesive injection at the beam-end contact interface forms a synergistic load-resisting system,and the failure pattern shifts to plastic yielding of the steel connectors and cracking of welds.The hysteretic curves are full and symmetrical,the initial stiffness is 2.98 times that of the interface-unbonded connection,and the residual deformation is reduced by approximately 40.8％.The equivalent viscous damping ratio reaches 18.3％at a rotation angle of 0.04 rad,representing an increase of 131.6％compared with the interface-unbonded connection.In addition,adhesive injections at the beam-end interface significantly improve the rotational compatibility of the connection.Overall,interface adhesive injection optimizes the force transfer path,suppresses the brittle failure of inorganic adhesive composite bamboo,promotes ductile energy dissipation of steel connectors,and enhances the stiffness,energy dissipation capacity,and deformation compatibility of the connection.关键词
