低屈服点钢在结构耗能减震中的应用
|
摘要
低屈服点钢的力学特点是屈服强度低,强度稳定,变形能力强,因此低屈服点钢的应用成为结构变形耗能的一个重要途径。对低屈服点钢在结构耗能减震中的应用现状进行介绍,提出低屈服点钢在弹性耗能结构中的应用方式,分析该弹性耗能铰的施工技术和耗能机理,为低屈服点钢的应用推广提供借鉴。
Low yield point steel possesses many mechanical properties such as low yield strength,stability of strength,strong deformability.Hence,low yield-point steels have important applications in structural energy dissipation.The paper introduces the research and applications status.A application mode of low yield point steel bars in elastic structures is pointed out.The construction technology and the energy dissipation mechanism of elastic hinged joints are analyzed.This paper could be valuable for the promotion of the low yield point steels and engineering practice.
