Response history analysis for the design of new buildings in the NEHRP provisions and ASCE/SEI 7 Standard; Part II, Structural analysis procedures and acceptance criteria

This paper represents the second part of a series of four publications on response history analysis for new buildings. It specifically focuses on modeling assumptions, consideration of important effects in the analysis, and interpretation of analysis results via global and local acceptance criteria. A statistical basis for development of both force- and deformation-controlled acceptance criteria consistent with the collapse probability goals of ASCE/SEI 7 is illustrated. More explicit sub-classifications of force- and deformation-controlled actions are proposed within the statistical framework. Additional philosophical discussion and simple probabilistic arguments are presented on the topic of consideration of unacceptable response, and guidance on addressing unacceptable response is given. Similarities and differences between the new requirements and those in other performance-based design guidelines are also enumerated.
