摘要
针对不同设计使用期结构,阐述了研究其设防烈度选取的必要性,同时介绍和分析了当前2种不同的基本烈度评估方法,对其中一些结论提出了异议,并提出了相关的解决方法,以供工程设计人员参考.
It is stated that it is necessary to study the selection of seismic design intensity on the structures with different design term.Meanwhile,two current different methods of the basic intensity assessment are introduced and analyzed.Different opinion on their conclusion is given and the correlative mean is offerred, which can be referred by engineering designers.
