evaluation of buckling load and dynamic performance of steel shear wall retrofitted with strips made of shape memory alloy

The most common imperfections of a steel shear wall are out of plane displacements that cause severe damage in both structural and non-structural elements. in this paper, the e ects of shape-memory alloys on steel shear walls are investigated. first, a numerical analysis, using the nite element method in abaqus software, has been carried out according to an experimental test. the results of the numerical analysis have been veri ed with experimental results. next, shape-memory alloy bers have been added vertically and horizontally to various parts of the steel shear wall. the results show that retro tting with the shape-memory alloy reduces the out-of-plane displacement of the steel shear wall under both cyclic and seismic loadings. besides, the buckling load in the steel shear wall increases when it is retro tted with the shape-memory alloy. also, the total outof-plane movement (accumulated absolute displacements) of the steel shear wall and nonstructural damage are controlled by the characteristics of a shape-memory alloy material called super-elastic.
