| 摘要： | Quantification of building system performance and response parameters such as response modification coefficient (R), system overstrength factor ðΩ0 Þ, and deflection amplification factor (Cd) is of great importance to reliably assess the performance of RC walls. Values of these parameters used in current design are mainly based on judgment and qualitative comparisons of the known response capabilities of relatively few lateral-force resisting systems in use. In order to assess the validity of these parameters, 20 special and 20 ordinary RC walls (archetypes), with varying seismic design conditons and physical parameters, were designed and modeled in a software framework. Static pushover and incremental dynamic analyses using 44 ground motions were conducted on each archetype using standard methodology, and the obtained adjusted collapse margin ratios are compared to established limits. Results indicate that the parameters of the archetypes designed based on current code provisions are within reasonable limits with the exception of archetypes having height-to-length aspect ratios of 3 or greater, where the use of a larger R value is suggested. |
