Strengths and deformations at stiffness changing points of reinforced concrete shear walls, such as at cracking, yielding and ultimate failure, are mathematically formulated based on mechanical models for flexural and shear resistance and deflection. A practical truss member model for the nonlinear dynamic analyses of wall-frame structures is presented, which consists of three vertical line elements and diagonal elements with rigid beams above and below. A method of determinating the elastic and inelastic properties of the line elements are given which conforms to the stiffnesses and strengths from the mathematical formula. A fair correlation is observed between the load deformation curves by the model and those of tested specimens including normal and ultra-high strength reinforced concrete shear walls.
