Nonlinear dynamic analysis is feasible for tall buildings, and can be done for reasonable cost. This paper looks briefly at the following questions. How does nonlinear dynamic analysis differ from linear? What are the steps? How are the analysis results used to assess structural performance? What skills are needed? Does nonlinear analysis lead to better design? Is it necessary to use capacity design? Is it necessary to consider geometric nonlinearity (large displacement) effects? How much computer time does it take? What are some other limitations? Can static pushover analysis be used instead of dynamic analysis? Copyright © 2006 John Wiley & Sons, Ltd.
