③The structure ductility demand of multi-degree-of-freedom systems is less than the equivalent single-degree-of-freedom systems. The preliminary view is that the R -μrelationship of single-degree-of-freedom systems at the moderate period is suitable for multi-degree-of-freedom systems.
③多自由度体系的结构延性需求小于等效单自由度体系,初步认为单自由度体系的R -μ规律在中等周期的多自由度体系中是适用的。
