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。
Focus on contrasting the similarities and differences between China and the United States in the process of using anchoring technology to fix structural members or non-structural members. In particular, seismic fortification requirements need to be considered, that is, problems requiring attention in the application of post-anchoring products under the action of seismic forces. Through deep comparison of the norms of China and the United States, the article aims to clarify the concepts of anti-seismic application and application of cracking concrete, and analyze the reasons behind the similarities and differences between the two countries’ norms, which will help engineering designers to better select suitable products and improve post- In the seismic safety.
