| Summary: | 碩士 === 朝陽科技大學 === 營建工程系碩士班 === 94 === The objective of current study is to explore the feasibility of post-fire assessment of concrete surface using infrared thermography, or IRT. Fire exposure of concrete specimens was simulated using electric ovens at different temperatures lasting for two hours. Uniform heat flux was applied to the surface of the specimen after cooling to room temperature. The thermal images were then taken immediately following the heat flux was terminated. In some cases, surface cracks may be associated with the area of higher temperature in thermal images. Similar results were found based on two- and three-dimensional modeling using finite element analysis. Furthermore, the effect of concrete surface emissivity on the thermal images was also investigated.
