- Abstract
- The main objective of this study is to develop a numerical cyclic loading protocol, based on available experimental and numerical studies, to quantify building system performance. The first part of the report reviews and compares existing experimental loading protocols that have been developed for the quasi-static cyclic testing of structural components and systems. Numerical studies that have included cyclic pushover analyses of structural components or systems are also reviewed. Based on this review, a numerical cyclic loading protocol is proposed for quantifying building system performance. In the second part of the report, a sensitivity analysis on the influence of the number of repeating cycles of the proposed numerical cyclic loading protocol on the equivalent elastic lateral stiffness and viscous damping properties of a 4-story reinforced concrete building model is investigated. Based on these results, the proposed numerical cyclic loading protocol is used in a simplified capacity spectrum methodology to estimate the seismic response of three different building structure models: two 4-story building models and a 12-story building model.
