| 摘要: |
| 分析了现有混凝土截面时效非线性分析的数据需求、算法和数据处理方式的特点,应用面向对象的参数化建模方法建立了描述与表达混凝土截面时效非线性分析信息需求的建筑信息模型(BIM),将考虑环境、荷载和内部因素影响的混凝土耐久性劣化理论应用于时效本构关系拟合和截面时效非线性分析,得到截面的内力-变形全过程时效信息模型;开发了基于BIM技术的混凝土截面时效非线性分析软件系统(Non-Linear Analysis System,NLAS),NLAS的实例应用结果表明,采用NLAS系统进行混凝土截面时效非线性分析能够提高分析过程中信息提取、交流和共享效率、减小数据流失和错误,本研究探索的BIM技术在混凝土截面时效非线性分析中的应用方法同样适用于其他建设工程领域． |

| Abstract: |
| The theory model of current RC section non-linear analysis is studied to clarify the data demand, algorithm characteristics and data processing pattern. Parametric object-oriented modeling method is adopted to express the data demand of RC section non-linear analysis and the corresponding building information model (BIM) is developed. The BIM is used to fit the constitutive relationship of concrete according to environmental condition, loads and internal factors. Furthermore, Non-Linear Analysis System is developed based on the BIM to automate the analyzing process of deterioration laws of RC section under conditions of environment, loads and internal acts. A case study is elaborated to demonstrate how the system is capable of conducting the RC section non-linear analysis and the results fit well with the data from detection on spot. |
