Title: Lifetime assessment of reinforced concrete structures under various impacts with multi-scale and multi-chemo-physical approaches

Inviter: Prof. Tamon UEDA
讲座内容简介：
钢筋混凝土结构在服役期间往往受到复杂环境及荷载耦合作用而发生劣化，如高温火灾、冰雪气候、钢筋锈蚀、混凝土碳化、碱骨料反应、持载徐变、疲劳荷载等。为实现结构的全寿命周期性能评估，报告人采用了多场（湿-热-化- 电-力）—多尺度（微观-细观-宏观）数值模拟分析方法。在本次报告中，将针对冻融循环和宏电池腐蚀的具体应用场景，详细介绍两种数值模拟分析平台的开发和优化过程。分别是：由北海道大学维持管理研究室原创开发的细观刚体弹簧元模型（Rigid Body Spring Method），和由东京大学混凝土研究室原创开发的混凝土三维力学-耐久性模型（COM3-DuCOM）。另外，利用后一平台对其他单一或复合劣化因素作用下（徐变、疲劳、 火灾、耦合冻害-锈蚀-碱骨料反应）的结构耐久性预测也将进行介绍。
Abstract: Reinforced concrete structures may suffer various deterioration factors from both environmental and mechanical impacts, such as fire attack, frost action, steel corrosion, carbonation, alkali-silica reaction, sustained load, fatigue,etc. In order to conduct the life-span assessment of structural concrete, multi-chemo- physical (thermal-hygral-chemical-electrical-mechanical) and multi-scale (micro-meso-macro) approaches are developed and adopted. In this presentation, two simulation approaches (1. Rigid Body Spring Model, originally developed by Maintenance Lab, Hokkaido University; 2. COM3-DuCOM, originally developed by Concrete Lab, The University of Tokyo) are introduced with the applications to frost damage and macro- cell corrosion in details. The applications to other deterioration factors and their couplings (creep, fatigue, fire damage, coupled frost-corrosion-ASR) will also be briefly presented.
