Abstract

Reinforced concrete cylindrical pipes (RCCPs) are one of the most widely used sewer conduits all over the world. These pipelines are very vulnerable to the corrosion and accident due to traffic loads, and other hazards such as earthquakes. One of the methods for rehabilitation of these old pipelines is rebirth method, in which a new plastic pipe is inserted into the old pipe to build up a new composite, layered pipe. In order to assess the strength and ductility properties of this composite pipe, a typical setup is analysed experimentally and numerically. In this paper, longitudinal behaviour of a typical rehabilitated jointed RC pipe is examined. The results showed a meaningful consistency between finite elements simulations and experimentations, also verified the data for using in seismic design procedure of similar rehabilitated pipes.
