Abstract: In the aftermath of the earthquake in Japan, U.S. engineers need to refresh their knowledge on designing MEP systems in earthquake-prone areas. Despite the incredible force of the March 11 earthquake in Japan, which had a magnitude of 8...
"You're running your water test too long- why are you going for more than 15 minutes?" "You're applying too much water- are you supposed to be replicating an 'actual' rainstorm, because this flow rate is more than...
Abstract: The article describes major revisions to Chapters 1 and 2 of the ASCE 7 standard and its accompanying commentary. These changes quantify the performance anticipated of structures designed using the loading criteria specified by the...

Abstract: Performance-based seismic design methods in the United States originated as a practical and effective means to mitigate the seismic risks posed by existing buildings and were later extended to permit development of new buildings capable...
Abstract: The Structural Engineers Association of California's (SEAOC's) Existing Buildings Committee (EBC) launched a new initiative now called the Earthquake | Performance Evaluation Program in 2007 to systematically gather useful...
Abstract: In the chaotic aftermath following a major earthquake, building owners often need rapid, accurate, and reliable damage information to resume occupancy or take appropriate measures for building recovery. Within 3-10 days of the event,...
This paper previews a system under development by the SEAONC Existing Buildings Committee (Building Ratings Subcommittee) intended to clearly communicate information about relative seismic risk to the general public to facilitate awareness and...
