【摘要】 随着装配式及消能减震技术的推广,附加消能减震技术的钢结构将会得到更大的发展空间。工程采用了屈曲约束中心支撑钢框架结构,并进行了构件性能化、小震弹性及大震弹塑性设计计算。由结果可知,通过性能化设计,屈曲约束支撑在小震下为结构主体提供了足够的刚度,大震下支撑屈服充分发挥了耗能作用,减震作用明显。文中对选用支撑产品抽检的实验参数提出了明确的要求,保证了屈曲约束支撑在大震下的变形能力,并在此基础上合理选择了支撑芯材材料,对类似项目起到一定的借鉴意义。更多还原

【Abstract】 With the promotion of prefabricated energy dissipation and shock absorption technology, the steel structure with additional energy dissipation and shock absorption technology will get more room for development.In this project, a steel frame structure supported by a buckling constrained center is used to study the performance of the members, the elasticity of small earthquakes and the elastoplastic design of large earthquakes. The results show that through the performance-based design, the buckling constrained support provides sufficient rigidity for the main body of the structure under small earthquakes, and the support yielding under the large earthquake fully exerts effects of the energy dissipation and the shock absorption is obvious. This article puts forward clear requirements on the experimental parameters for the selection of support products for random inspection, which ensures the deformation capacity of the buckling restrained support under large earthquakes. On this basis, the support core material is reasonably selected, which has a certain reference significance for similar projects.更多还原
