Three-spring Model for Spatial Walls

摘要：

　　Shear wall structures,frame-shear wall structures and frame-tube wall structures are usually used in tall buildings,especially in China seismic regions.How to simulate the mechanical behaviors of these walls is the key to elastic-plastic analysis for tall buildings.Based on two-spring model,a nonlinear model for spatial walls is proposed.In this model,the axial,shear and flexural elastic-plastic deformation of the walls can be considered,the deformation compatibility between the wall and beam elements is also considered.The model was used to analysis the elastic-plastic behavior of spatial walls.Calculation example for verifying the model indicates that the result obtained by this method has the characteristics of fewer degrees of freedom and high accuracy.Therefore the nonlinear model for spatial walls provides a practical and efficient analysis method for tall buildings with complex type.
