Numerical Simulation of Shear Wall Structure with Beam Joints in High-rise Building Construction
To evaluate the stress performance of shear wall structure connecting beam nodes in high-rise building construction,this study proposes a numerical simulation based method.This method connects the shear wall panel to the edge components through fishtail welding technology,sets stiffeners at the center as the origin,and uses double-sided corner welding to fix them.Select a specific connecting beam as the specimen,and use quasi-static loading technology according to JGJ/T 101-2015 standard.Firstly,apply a vertical load of 300 kN,and then apply a horizontal load.Monitor the displacement and stress changes of the rod after being subjected to force using a dial gauge and strain gauge.The experimental results show that this method can effectively simulate the actual stress state of the connecting beam node.The bearing capacity of the specimen is positively correlated with the axial compression ratio and the reinforcement ratio of the hidden support.As the displacement of the beam end increases,the degradation coefficient of the bearing capacity first increases and then decreases.When the reinforcement ratio is 1%-2%,the stability of the specimen is excellent,with good deformation ability and ductility.
