博士 === 國立臺灣大學 === 土木工程學研究所 === 101 === Lack of seismic performance is a common problem for a large number of the existing school buildings in Taiwan. Development of effective and economical retrofit method is a stringent issue. Retrofit method by adding sandwich columns onto the partition brick walls has been proposed. In this paper, the feasibility of the proposed method was verified by cyclic loading tests, shaking table tests and in situ tests, including six specimen with and without retrofit. With retrofit, the maximum base shear strength and ductility were increased obviously. In this paper, three kinds of seismic evaluation methods, including the preliminary evaluation, simplified pushover analysis and nonlinear static pushover analysis, were used to evaluate the seismic performance of the six specimen. Because no windows and doors have to be demolished by the proposed method, it is an environment-friendly, economic and efficient retrofit method for seismic upgrading of the existing school buildings.
