结构动力分析表明,在地震作用下,结构的不同部位有不同的延性要求,在新的抗震设计规范中已反应了这方面要求。本文进一步探讨了在抗震设计中的延性问题,目的是如何因地制宜,在遵守规范的要求下,使设计更为经济合理。 Structural dynamic analysis shows that under the action of earthquake, different parts of the structure have different ductility requirements, which have been reflected in the new seismic design code. This paper further discusses the issue of ductility in seismic design. The purpose is how to adjust measures to local conditions and to make the design more economical and reasonable under the requirements of the compliance specification.
