Research Abstract

This study focus on seismic design methodology of composite rehabilitation method for sewage concrete pipe. First we carried out the laboratory experiments of the infilling cement mortar changing material strength and made sure their effects to bounding strength. The parameters of material strength of cement mortar are used for seismic assessment of rehabilitated pipe in pipe-axis and cross-section directions, respectively. Effects of rehabilitation and rehabilitation method were shown.
