【 摘 要 】
Because of the good performance of the fiber model in the simulation of axial and bending coupling, the new fiber model considering the axial, bending and shear effects is established to analysis the nonlinear properties of RC shear wall. The way of the shear fiber distribution in the cross section consistent with the axial fiber and each shear fiber current state of stiffness get from the independent shear hysteretic rules, then establish tangent element stiffness matrix containing the axial, bending and shear deformation under complex loading paths. Two different cross-section fiber models is compared. Compiling corresponding calculation program to simulate a shear wall's nonlinear performance under monotonic load and compare with the laboratory RC shear wall test results to verify the validity of the model.
