The response quantities considered include story displacements, interstory drifts, story shears and story overturning moments. Singlemode pushover methods that were evaluated include the N2 and ASCE-41 coefficient methods. Multi-modal pushover methods such as the modal pushover and the consecutive modal pushover method also were evaluated. Target displacements were estimated using R-C1-T relationships as well as more elaborate approaches such as the SPO2IDA (Static Pushover to Incremental Dynamic Analysis) tool and nonlinear response history analyses using equivalent single-degree-of-freedom systems (ESDOFs). The results indicate the adequate performance of single-mode methods for low-rise buildings deteriorates as the number of stories increases and differs according to the response quantity examined. The multi-mode techniques generally can extend the range of applicability, but at the cost of additional computation and complexity without ensuring reliability of the results. Therefore, appropriate care is advised in all applications of nonlinear static methodologies when used for quantitative, rather than qualitative, estimation of seismic performance. This work has been carried out in the framework of the ATC-76-6 project.
