PEER Reports

Reinforced concrete walls are used commonly to resist lateral loads; often, concrete walls have
three-dimensional configurations to maximize stiffness and strength. Seismic design, evaluation,
and retrofit of concrete wall structures often requires nonlinear analysis to predict performance,
and assessment of earthquake risk for regions and individual structures often requires nonlinear
analysis to predict damage, loss of functionality, and repair time and cost. This report presents the
results of a research study in which high-performance cloud-computing resources were used...

These are the proceedings of the twenty-first working conference of the International Federation
of Information Processing (IFIP) Working Group 7.5 on Reliability and Optimization of Structural
Systems, which took place at the University of California, Berkeley, USA, on August 19–21, 2024.
This volume contains 15 selected papers from the 20 presentations delivered at the conference.
The conference was supported by Pacific Earthquake Engineering Research (PEER) Center, and
by the University of California, Berkeley, which provided outstanding facilities in the conference

The magnitude 6.0 South Napa Earthquake of August 24, 2014, took the lives of two people, injured 300 others, and caused moderate to severe damage to more than 2,000 structures. It is one of the first damaging earthquakes to strike a major metropolitan area in the State of California in over two decades. During that time period, California’s population has grown by over 25%, the state’s economy has tripled, and a great many of the state’s new residents and businesses have never experienced a major earthquake. It is almost guaranteed that there will be a major damaging earthquake somewhere...

Construction or detailed evaluation of transportation infrastructure requires site-specific ground motions for input into nonlinear structural models. These site-specific ground motions are generally selected based on the magnitude, distance, and site condition of the recorded ground motion. A preliminary study performed by Slate Geotechnical Consultants found that duration and spectral acceleration are negatively correlated for large-magnitude earthquakes recorded on soft-soil sites (Vs30<360 m/s). This means that if the target spectral acceleration is above average, then the average...
