Abstract:

Although the existing shearwall model has high numerical precision, computation complexity and difficulties in the sampling process of each parameter have limited its application. In this paper, a simple wall element model based on the nonlinear element model for beams by comparing the existing models is proposed. The proposed model is composed of beam element representing axial deformation and flexural deformation only, and shear element representing shearing only. The stiffness matrix of the proposed element is also established. An example is calculated and compared with the tested results, showings that the model test has relatively good accuracy.
