中、美在后锚固抗震技术方面的对比分析

摘要

This article focuses on the differences of seismic design for structural or non-structural components by using the post installed anchor system in America and China,especially under the considering of earthquake impact.By the contrast of American code and Chinese code,the article clarifies those principles such as using range for seismic,cracked or un-cracked concrete etc.,deeply analyzes the background of those differences in order to benefit design engineers from selecting suitable products and improve the safety level of the post installed anchor system in seismic area.%着重对比中、美两国在使用后锚固技术固定结构构件或非结构构件过程中的异同,特别是需要考虑抗震设防要求,即地震力作用下,后锚固产品应用中需要注意的问题.文章通过深入对比中、美两国的规范,旨在明确抗震适用、开裂混凝土适用等概念,剖析两国规范的异同背后的原因,有利于工程设计人员更好地选用合适产品,提高后锚固应用中的抗震安全度.
