The axial load-biaxial bending moment interaction model (N-M model) is developed based on the metal plasticity theory, and its reliability in structural analysis is evaluated. Employing CANNY program, linear and nonlinear dynamic time history analysis is conducted to a 32-story SRC structure. The dynamic responses are compared between N-M model and fiber model cases. The results show that N-M model can simulate well the dynamic response of the high-rise hybrid structures. Besides, N-M model has clear mechanical concept and is much simpler compared to fiber model, and the computational efficiency can be greatly improved by using N-M model. |
