Abstract

The presented method of analysis has the unique feature in its exact inclusion of the coupling between axial force, primary and secondary moments and their conjugate axial and bending strains, and, most importantly, the incorporation of the effect of curvature along the length of the member. Degradation of the material, once yielding has occurred at certain locations is accurately modeled, and the structural behavior for in-plane lateral dynamic loading of 2D shear frame beam-columns is predicted with particular reference to material nonlinearity and taking into consideration any geometrically nonlinear effects. Using detailed incremental procedures, the stress-strain relationship is derived for beam-column element. The proposed methodology ultimately provides accurate force-lateral deflection curves. The results of the proposed rigorous model compare favorably to the results of the FEA, and indicate that the proposed incremental approach is very reasonable.
