Seismic Tomography as a High Performance Application
20th International Symposium on High-Performance Computing in an Advanced Collaborative Environment (HPCS'06), 2006In this paper we present a dipping layer, gridded cell, ray trace tomographic system built at Memorial University for determining seismic velocity tomograms need for processing reflection and vertical seismic profiles. Based on Java, the JRAY system is portable and the code is open source which allows for modifications for research purposes. Our system

Simplified seismic performance assessment and implications for seismic design
Earthquake Engineering and Engineering Vibration, 2014The last decade or so has seen the development of refined performance-based earthquake engineering (PBEE) approaches that now provide a framework for estimation of a range of important decision variables, such as repair costs, repair time and number of casualties.

SOAR Telescope seismic performance II: seismic mitigation
SPIE Proceedings, 2016We describe design modifications to the SOAR telescope intended to reduce the impact of future major earthquakes, based on the facility’s experience during recent events, most notably the September 2015 Illapel earthquake. Specific modifications include a redesign of the encoder systems for both azimuth and elevation, seismic trigger for the emergency ...

Seismic Performance of Timber Bridges
Transportation Research Record: Journal of the Transportation Research Board, 2000Compared with the seismic performance of concrete and steel highway bridges, the seismic performance of timber bridges is not well understood. This is because, historically, little effort has been spent on documenting the seismic performance of timber bridges in past earthquakes or conducting research to develop an improved understanding of the seismic

Seismic performance of riveted connections
Journal of Constructional Steel Research, 2002Abstract The results of tests on seven full-scale T-stub riveted connections are described. The differences in connector behavior between modern bolts and older rivets are discussed, and the effect of encasement on the strength, stiffness, and ductility of older steel connections is highlighted.

Performance-Based Seismic Design
2012An approach is presented to structural optimization for performance-based design in earthquake engineering. The objective is the minimization of the total cost, including repairing damage produced by future earthquakes, and satisfying minimum target reliabilities in three performance levels (operational, life safety, and collapse).

Performance-Based Seismic Design
2015Performance-based seismic design, which is a relatively new concept, came into existence as a means to ascertain the likely performance of an existing building structure during an earthquake. However, this approach is equally applicable to new buildings being designed.

Seismic performance of suspended ceilings
2017Non-structural elements (NSEs) have frequently proven to contribute to significant losses sustained from earthquakes in the form of damage, downtime, injury and death. In New Zealand (NZ), the 2010 and 2011 Canterbury Earthquake Sequence (CES), the 2013 Seddon and Cook Strait earthquake sequence and the 2016 Kaikoura earthquake were major milestones in
