Some observations on performance-based and reliability-based seismic design of asymmetric building structures

In previous work by the second author and others, a framework for a reliability-based, performance-based seismic design procedure was presented. That framework was based on static pushover analyses of two-dimensional models of building structures. In this paper, some preliminary observations and results are presented from a study in which the framework is extended to be used with three-dimensional analysis models to explicitly account for the torsional behavior of asymmetric building structures.
