This article combines engineering examples to design and study the connection nodes in the design of precast concrete external wall panels.Starting from the deformation of the main structure that the external wall panels adapt to,it analyzes the seismic elasticity of the connection nodes and their failure to yield during large earthquakes;When calculating the reaction force of wall panel supports for node design,it is necessary to input the actual stiffness of the node into the wall panel for calculation;When conducting finite element analysis of nodes,the overall modeling and verification of wall panels,main structural floors,and connecting nodes should be carried out;The main research focuses on the connection node of a point supported rotating precast concrete external wall panel.Through the design and finite el-ement verification of this node,it is shown that it has good stress performance,simple structure,and convenient construction.
