The High Level Sewer (HLS) is a masonry conduit built around 1901. Following a large rainstorm, the HLS developed internal pressure that caused water to overflow through the manholes and flood parts of the Roslindale neighborhood. The manholes...
The 72 in. dia. North Coast Superaqueduct carries water 70 km from Arecibo to San Juan. Just after construction, the aqueduct experienced failure of two pipe segments during a transient pressure event caused by sudden closure of a valve. SGH...

The American Society of Mechanical Engineers (ASME) and the American Nuclear Society (ANS) have developed a "Standard for Level 1/Large Early Release Frequency Probabilistic Risk Assessment for Nuclear Power Plant Applications." The...
Abstract: This paper presents a summary of the research performed for Water Research Foundation on the evaluation of condition assessment and remaining service life prediction/failure margin analysis technologies in use for prestressed concrete...
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...
Abstract: Under sponsorship of the Federal Emergency Management Agency, the Applied Technology Council is engaged in a multi-year effort to develop next-generation performance-based seismic design criteria. The criteria will be applicable to the...
Abstract: Design procedures for seismic resistance contained in building codes are intended to enable buildings to provide acceptable levels of performance in earthquakes, but the procedures are not truly performance-based. These procedures...
Abstract: The Applied Technology Council has initiated the ATC-58 project to develop next-generation performance-based seismic design guidelines applicable to the design of new buildings and upgrade of existing buildings. The guidelines will...
