Analysis of Fluid-Structure Interaction in Piping Systems Excited by Seismic Actions

Abstract

This paper is about the behavior of a liquid-filled pipe system excited by seismic actions. A coupled model with strong interaction, which includes hydraulics interface coupling, Poisson coupling and junction coupling was developed. Hydrodynamic behavior of a liquid filled pipe was studied in experimental installation. Through the application and exploration of computational model it is possible to obtain some general indications for conception and design of piping systems, such as water supply systems, in order to reduce seismic vulnerability. It is also possible to present some recommendations about water supply system operation.
