摘要：

Combining the refined structural element models with the efficient and robust numerical integration algorithm, a constitutive model-based dynamic whole-process analysis for RC structures was implemented. A brief introduction to the element modeling approach, the structural analysis method as well as the material and component failure criteria was provided. Taking a certain prototype reinforced concrete frame-shear wall structure as an example, different seismic collapse simulations with elasto-brittle, elasto-plastic and stochastic damage constitutive models of concrete were compared and investigated. Research results indicate that the concrete constitutive relationship plays a fundamental role in the collapse analysis of structures and improper selection of constitutive models of concrete will lead to wrong collapse modes and analysis results. Moreover, the stochastic damage constitutive model of concrete is capable of predicting the structural strong nonlinear behaviors and is available for the simulation of overall collapse process of complex concrete structures. © 2016, Editorial Office of Journal of Building Structures.
