SCEC Ground Motion Simulations and Engineering Applications Workshop

Participants: 100 maximum

Date: June 25, 2018
Time: 9:00am-5:00pm
Location: Westin Bonaventure Hotel, Los Angeles

Cost: $100

Convener: Christine Goulet
Date: June 25, 2018
Location: Westin Bonaventure Hotel, Los Angeles

OVERVIEW: As non-linear response history analyses becomes more prevalent in practice, the need for close-in, large magnitude records similarly increases. However, there is still a paucity of data for those types of records. In addition, the desire to perform site-specific analyses representing the most plausible ground motions at a site have increased the need to use simulated ground motion time series. The ground motions can be simulated for specific fault geometries and include the region-specific characteristics of the wave propagation problem. This workshop will highlight recent progress in ground motion simulations and their validation for engineering application uses.

The workshop is hosted by the Southern California Earthquake Center (SCEC), which champions several computer-based simulation techniques. We will cover various scientific aspects of ground motion simulations, including the science behind them, the important assumptions underlying their development and their validation for various applications. The workshop is targeted to research and design engineers and will also to cater to scientists interested in ground motion simulations.
