Jul 19, 2017 | Structural Engineering

Ms. Phoebe Cheng (Principal Engineer at SC Solutions) presented a case study on the seismic analysis and performance-based retrofit design of several large buried water storage reservoirs at the 3rd International Conference on Performance-based Design in Earthquake...

Performance Based Design with 3D Dynamic SSI and FSI Analysis for Large Buried Water Storage Reservoirs

Jul 16, 2017

Seattle Public Utilities (SPU) has four large, buried concrete reservoirs constructed between 2006 and 2013 and ranging in size from 5MG to 64MG (20 to 240 million litres). These reservoirs are essential for maintaining post-seismic event fire suppression and domestic...

Seismic Performance Evaluation of Underground Structures – Past Practice and Future Trends

Jul 16, 2017

Underground structures are an integral part of civil infrastructure and play an ever-increasing role in a rapidly urbanizing world. Underground structures have generally performed better than aboveground structures during earthquakes when transient motions are...

Comparative Study of Time-Domain versus Frequency-Domain Seismic Soil-Structure Interaction Analysis of Pressurized Water Reactor Containment Building

Oct 19, 2016

The equivalent linear approach in frequency domain (ELFD) is the current state of practice for performing seismic soil-structure interaction (SSI) analysis of nuclear facilities. Although the ELFD method would produce reliable results for small to medium intensity...

Probabilistic Soil-Structure Interaction Analysis of Nuclear Power Plant Structures for Probabilistic Risk Assessment

Oct 19, 2016

As a partial response to post-Fukushima Near-Term Task Force (NTTF) Recommendation 2.1 from the Nuclear Regulatory Commission (NRC), several operating nuclear power plants commissioned seismic probabilistic risk assessment (SPRA) studies to evaluate the impact of...
