Impact of ground-motion duration on nonlinear structural performance: Part II: site- and building-specific analysis

This study’s Part I proved that ground-motion duration could play an important role when assessing the nonlinear structural performance of case-study inelastic single degree-of-freedom systems. However, quantifying effects in many practical/more realistic engineering applications is not trivial, given difficulties decoupling from other characteristics. II, introduced this article, explores impact on by numerically simulating response reinforced concrete bare and infilled building frames. Advanced computational models incorporating components’ cyclic in-cycle strength stiffness deterioration, destabilizing [Formula: see text] are used. The proposed methodology relies generalized conditional intensity measure approach to select ground motions. allows selecting records consistent with seismic hazard at a target site, both terms spectral shape duration. Those employed as input cloud-based analyses. Variance analysis used quantify response. Furthermore, vector-valued fragility vulnerability alternatively using peak- cumulative-based demand parameters derived. Results show higher damage/loss estimates can be attained increases. Relative differences up 44% found median values for pre-code frame comparing scalar conditioned average pseudo-spectral acceleration significant durations 35 s.
