【Abstract】 Based on the commonly used plane frame structure analysis method, the nonline behavior of material is considered. By continously verifying the elements stiffness and the stiffness matix of structure, the real internal force and deflection of RC or PPC hyperstatic structure are pressed on. As compared with other methods, this approach has the advantages of being concise in theory, simple and convenient for implementation, and satisfactorily correspond with the tested results.更多还原
