This study attempts to expand the application of the conventional 2D lattice model, which can express the shear resisting mechanism of RC structural members, to a 3D analytical model. Use of a 3D lattice model for the simulation of torsional and biaxial responses of RC structural members is presented. The results of static analysis are compared with several sets of experimental results for RC beams/columns subjected to pure torsion or cyclic combined loads of torsion and bending. In addition, the dynamic analysis of RC columns subjected to bilateral seismic loading is carried out. The applicability of 3D lattice model to the response prediction of RC structural members under 3D loading is examined by comparing analytical and experimental results.
