  17. NUMERICAL SIMULATION OF THE PERFORMANCE OF INTEGRATED CEILING-SPRINKLER SYSTEMS

    24 Feb 2015 | Publications | Contributor(s): Siavash Soroushian, Manos Maragakis

    Suspended ceiling and fire sprinkler piping systems are one of the most vulnerable types of nonstructural systems that have suffered costly damage during past earthquakes. The seismic performance of these two systems are poorly understood due to their heterogeneous nature. In order to fill this...
