Broader Impacts Data obtained in this study can help building owners and policy-makers make informed decisions about mitigating seismic risks in California. Predicted collapses and damage in specific types of buildings can be used by building owners in order to quantify the value of investment in seismic strengthening, in terms of reduced risks in future earthquakes. Scenario assessments of the performance of RC moment frames throughout the Los Angeles region serve to benchmark the level of seismic performance achieved by today’s seismic building code provisions, which can be used by building code committees to
calibrate and inform future development of seismic provisions. Comparative assessments of older (nonductile) and modern (ductile) RC frame structures provide much needed data for the ongoing policy debate in California regarding mitigation of potentially vulnerable non-ductile RC frame structures.
Evaluation of non-ductile structures in this study quantifies the impact of design deficiencies on seismic performance of Southern California’s building stock, an effort that is synergistic with other groups’ efforts to mitigate risks posed by these buildings, especially PEER and the Concrete Coalition. Local
governments can make use of better data about the extent of building damage and collapse to plan emergency response in advance of a major earthquake event.
