Inspection and Repairment of Separation of Finisher on Outer Wall of RC Structures

本研究对钢筋混凝土结构外墙饰面的热像检测和内部缺陷的电雷达法检测进行了以下两方面的研究：1)热像检测与分析：通过控制混凝土模型缺陷试件的两侧，进行了一系列的实验研究。用三维有限元方法对计算结果进行了精确的模拟，得出了有限元分析结果和最佳测量条件。2)电雷达法试验研究：进行了内部缺陷或加固的模型试验。本研究对钢筋混凝土结构外墙采用锚销法进行了三维网格法修补试验：1)材料的选择：通过剪切试验、粘结试验和弯曲试验进行了一系列的选材试验；2)改进网目的试验：进行了改进网目的试验。并使背面材料的效果固化。

In this research, two studies on inspection by thermography for finisher on outer wall of RC structures and by electric radar method for internal defect are carried out as follows ;1) Experimental and analytical studies by thermography : A series of experiments are carried out by controlling both sides of concrete specimen with model defect. The results are simulated by 3D finite element method accurately, and the limitations and best condition for survey are obtained from these analytical results.2) Experimental study by electrical radar method : A model experiment for estimation of internal defect or reinforcement are carried out. And some hidden reinforcements are found by this method on gallery on the first floor of Hagia Sophia.In this research, two experiments 3D mesh with anchor pin method for repairment of outer wall of RC structure are carried out as follws ;1) Selection of material : A series of experiments for selection of material are carried out by shear test, adhesion test and bending test.2) Experiment with improved mesh : A experiment with improved mesh are carried out. And effect of back material is charified.
