Analysis of seismic actions in pipe infrastructures security

The current research work aims at analysis of seismic analysis in hydraulic infrastructures. The extreme importance of this subject is the simulation of an abnormal action in a main pipe water drinking system in the Pumping-Station of Telheiras, from Lisbon Water Supply System, which caused pipe displacements and breaks in some supports. To seek the vulnerability of these hydraulic systems (to different typical loads), many case studies were developed by water hammer and structural models. The analysis was developed in order to show the possible consequences in terms of displacements, when the system is submitted to different loads and type of supports. It is equally emphasized the importance of integrated analysis (fluid-structure interaction) and the purpose of supports in water pipe systems in the infrastructures design.
