Lifeline Systems
The intent of this study is to impose external loading conditions to test specimens that are representative of the significant deformations possible during earthquake-induced ground motions such as landsliding, fault rupture, and liquefaction-induced lateral spreading, characterizing the pipeline system capacity.
The intent of this study is to investigate the difference between a serrated faced flange connection and a non-serrated faced flange connection; mainly to determine whether one would leak sooner than the other.
Cast iron, wrought iron, and bare steel natural gas distribution pipes—legacy pipes—make up 3% of the nearly 2 million miles of utility pipes in use, but account for a disproportionate number of gas leaks and pipe failures compared to more recently replaced infrastructure. REPAIR seeks to reduce natural gas leaks from these pipes by developing a suite of technologies to enable the automated construction of new pipe inside existing pipe.
