【摘要】 通过对单自由度体系R-μ-T关系代表性研究成果的总结评述,得出两个重要结论:1)总体来看,各代表性研究成果在基本趋势上具有良好的一致性,所获得的R-μ-T规律可以作为抗震设计的重要参考准则;2)单自由度体系R-μ-T规律初步揭示出设计良好的抗震结构所具有的延性能力是结构可以采用多遇地震作用进行承载能力设计,却能在强震下取得相对令人满意的抗震性能的主要原因。更多还原

【Abstract】 Based on summary and analysis of the main research findings regarding R-μ-T relations for a single-degree-of-freedom system,the following two important conclusions can be drawn: 1) In general,these research findings are consistent with each other.The R-μ-T rule can be an important reference criterion for seismic design.2) Proper design and extendibility ensure the relatively satisfactory performance of the structure under stronger earthquake action.更多还原
