基于频率的结构地震损伤识别方法具有快速、无损的优点,在试验研究的基础上,运用ABAQUS对高温下钢筋混凝土简支板进行动力特性分析,得出了高温下钢筋混凝土简支板温度场的分布规律,并在此基础上分析配筋率对钢筋混凝土板固有频率的影响以及温度场对简支板固有频率的影响;进一步建立温度场下钢筋混凝土简支板固有频率与混凝土损伤深度间的对应关系。通过分析研究可以看出板的温度和钢筋的温度直接影响板的固有频率。
Based on the experimental study, the dynamic characteristics of reinforced concrete simply supported slabs under high temperature are analyzed by ABAQUS, and the temperature field of reinforced concrete simply supported slabs under high temperature is obtained On the basis of which, the influence of reinforcement ratio on the natural frequency of reinforced concrete slab and the influence of temperature field on the natural frequency of simply supported slab are analyzed. Furthermore, the relationship between the natural frequency of reinforced concrete simply supported slabs and the damage depth of concrete Corresponding relationship. Through the analysis and study can be seen that the temperature of the plate and the temperature of the bar directly affects the natural frequency of the plate.
