Quantitative Risk Assessment Using Rupture-to-Rafters Simulations 
Tuesday, 26 August 2014,  3:00 -  5:00
 Hits : 4628 

Rupture-to-rafters simulations consist of the unzipping of a fault in the form of an

earthquake, propagation of the radiated seismic energy through the earth’s crust and

mantle to the sites of engineered structures, the nonlinear wave propagation through the

soils at the sites into the engineered structures and, simulation of damage to the

components of the structure at multiple scales as well as the simulation of global collapse.

In this talk, I will present a quantitative method that uses rupture-to-rafters simulations

to answer questions such as “what is the probability of collapse (or the probable maximum

loss) of (to) a building (or a portfolio of buildings) at various locations in a region from

earthquakes on a particular regional fault over the next N years”. I will present the results

of a prototype study focused on the San Andreas fault and existing tall steel moment

frame buildings in southern California.
