Based on the multi-layer shell element model that is now widely used in the nonlinear analysis for the shear wall structure,different constitutive models of concrete and reinforcement are discussed in this paper.Selected in this discussion were two models:a new constitutive model for concrete,referred as microplane model,which could precisely simulate the nonlinear behaviors of concrete under complicated stress conditions,and a constitutive model for reinforcement,which could accurately modeling the hysteretic behaviors of the reinforcement.Some shear wall tests were analyzed to demonstrate the precision of the proposed model.

在适用于剪力墙结构非线性分析的分层壳墙单元模型基础上，对其中的混凝土本构模型和钢筋本构模型进行讨论，采用一种能较好的模拟混凝土在多轴复杂应力状态下特性的microplane模型和一种能够全面反映钢筋在往复载荷下各种复杂受力特性的钢筋本构模型，分别模拟混凝土和钢筋的力学行为特征。

The data model is the data source for the integrated mining which is built by using Snow Flake Schema. The integrated mining model consists of local mining and global mining. That is to say, firstly, monitoring cell mining, point mining and monitoring data mining are fulfilled respectively, then global mining model is run to opimize the monitoring process. The paper brings forward how to build up these models and the framework, and what variables should be delivered.
