Abstract

Railway viaducts have been constructed since the end of the Taisho period in urban areas, and many of them have been used up to now. The reinforcement work of the beam may be necessary from the viewpoint of seismic capacity and durability in such viaducts. Therefore, we developed the reinforcement method effective in both flexural strengthening and shear reinforcing for the beams using arch shaped steel plates. In this paper, we introduce the outline of reinforcement method and the result of cyclic loading tests, and propose a design method.
