Development and Application of Shear Wall Macro-element Based on Vector Form Intrinsic Finite Element
摘要
Abstract
In this paper,a shear-wall macro element (MVLEM) based on the Vector Form Intrinsic Finite Element (VFIFE) is developed in Fortran.The numerical simulation of the low-cycle loading test of the shear wall is carried out by using the constitutive model and the Fischinger spring constitutive model.This method can show the reaction of the nonlinear behavior,hysteretic behavior and pinch performance of shear wall.The calculation of the internal force of the element does not need the element stiffness matrix,which has a great advantage in programming,and the computation efficiency is higher than the traditional finite element program.This method for the calculation of large shear wall structure has engineering value.关键词
