| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程系 === 100 === The purpose of this study is to discuss the seismic performance of a deteriorating reinforced concrete (RC) shear wall, including finishing materials. At first, this study builds a model for estimating the occurrence time of chloride-induced corrosion of reinforcing steel embedded in concrete under various finishing materials. Additionally, this work classifies the finishing materials into three groups, i.e., without finishing materials, cement mortar and resin materials. To evaluate the strength and displacement of a deteriorating RC shear wall, this study combines the degradation of mechanical properties of reinforcing steel induced by corrosion with the Softened Strut-and-Tie Model. Finally, to associate with Structural analysis software (ETABS), this study uses the deteriorating equivalent truss model to simplify the simulation of deteriorating RC shear walls and define reduction factors of nonlinear plastic hinge properties under various sites and finishing materials.
