Abstract: Different tension-compression elastic moduli are introduced in both small- and large-displacement finite element formulations. Corresponding numerical methods and three-dimensional finite element iterative programs for geometric and material non-linearities are developed. A numerical example is presented for the load-carrying capacity of beam-column structures of different tension and compression modulus. Factors affecting the load-carrying capacity are also discussed, which include constraint conditions, couple moments, ratios of tensile-to-compressive modulus. The results show that the load-carrying capacity of the beam-column structure of different tension-compression moduli is significantly different from that of the beam-column structure of equal tension-compression moduli.
