Evaluation method of seismic performance for RC viaducts with columns of shear failure mode

Abstract

It is often difficult to conduct seismic retrofitting of all columns in railway RC viaducts by restriction of construction. In such a case, it is necessary to conduct verification of seismic performance taking no retrofitting columns of shear failure mode into consideration. However there are few studies on evaluation method of seismic performance for RC viaducts with columns of shear failure mode. In this study, evaluation method of seismic performance was proposed for such a viaduct.
