Experimental Seismic Study of Pressurized Fire Sprinkler Piping Subsystems.

摘要

A fire extinguishing sprinkler piping subsystem not only accounts for a significant portion of typical investment in building construction, but also represents one of the key components that ensures the functionality and safety of a building. However, recent earthquake events have demonstrated the vulnerability and sometimes poor performance of fire extinguishing sprinkler piping systems, which can cause a wide range of damage resulting in substantial property loss, loss of building functionality, as well as posing a significant hazard in potential fire spread and loss of life. Limited research has been conducted on sprinkler piping subsystem under seismic loading and information obtained from previous studies is not sufficient to fully describe their dynamic response and failure mechanisms.
