摘要
建筑中常见的装配式钢筋混凝土结构虽构架稳固,但存在抗震性能较差的缺陷和一定的安全风险。屈曲约束支撑则能很好地克服这一弱点,能在结构中充分发挥其抗侧力,是一种集抗侧力和耗能为一体的耗能减震构件,能理想地实现结构的抗震设防建设需求。结合深圳市某酒店工程项目,对屈曲约束支撑在装配式结构中的加固应用展开分析探讨,并对其安全性能进行研究阐述。
Although the framework of the prefabricated reinforced concrete structure is stable,it has the defects of poor seismic performance and some safety risks.Buckling restrained braces can overcome this weakness,and give full play to its lateral resistance in the structure.It is a kind of energy dissipation and shock absorption structure that integrates lateral resistance and energy consumption,and it is ideal to achieve the construction requirements of seismic fortification of the structure.Based on a hotel project in Shenzhen,this paper analyzes and discusses the application of buckling restrained brace in the reinforcement of fabricated structure,and expounds its safety performance.
