000013714 520__ $$2eng$$aThe effectiveness of simplified nonlinear models for seismic assessment of steel moment frames using single and multi-mode nonlinear static methods compared to nonlinear response history analysis is discussed in this paper. Results of studies of different steel archetype buildings with perimeter steel moment resisting frames are compared with those from nonlinear response history analysis (NRHA). Simplified modeling of gravity systems is also discussed. It is demonstrated that the nonlinear static procedure (NSP) has many limitations for quantitative assessment of moment frame demands even for relatively low-rise structures. But it has much value in understanding important behavior characteristics that are not being explored in a NRHA in which engineers usually focus on a “blind” demand/capacity assessment rather than interpretation and visualization of behavior. The conclusion is that both NSP and NRHA have intrinsic value and that it is advisable to employ a combination of both to understand seismic performance and quantify important engineering demand parameters. This study is part of a recent National Institute of Standards and Technology (NIST) funded project through a joint venture partnership of the Applied Technology Council (ATC) and Consortium of Universities for Research in Earthquake Engineering (CUREE) on improvement of nonlinear multiple-degree-of-freedom modeling for design decisions of regular and irregular structural systems (NIST GRC 10-917-9).
