Abstract
Taking a building under construction as an example, based on ABAQUS software, studies the failure mode, hysteretic curve, displacement ductility and energy consumption capacity of ALC external wall panel under three working conditions of assembled stiffened column frame brace system, assembled frame system and cast-in-place frame system.The simulation results show that:1.Under the action of low cycle load, the assembled stiffened column frame support system has no damage,the maximum stress value is 6.98 MPa, which is located at the position of steel plate at the column bottom; 2.Under the condition of ALC hanging wall plate, the structure ductility is better; 3.Part of the energy consumption is borne by the light material hanging wall plate, and the stiffened column frame support system has higher energy consumption capacity.The assembled ALC external wall panel based on the rigid column frame support system has better mechanical performance, can significantly improve the energy consumption capacity of the overall structure, and has high construction feasibility,economy and engineering application value.
