SUMMARY This paper presents a discussion of the critical issues identified by the Los Angeles Tall Buildings Structural Design Council Evaluation and Strengthening committee work as it relates to the structural engineers determination of design capacity for a limit state. The capacity design incorporates professional experience (judgment) in a transparent way. It also discusses the peer reviewer and building officials' responsibility in evaluating the structural engineers' establishment of values for the expected value and the coefficient of variation of all random variables in the capacity equation for a selected limit state. The focus is on tall buildings in the Los Angeles region. Copyright © 2012 John Wiley & Sons, Ltd.
