最近,结构的保险丝在地震工程的地里成为了一个重要问题。由于有金属性的结构的保险丝的大楼的闲差事曲线的 trilinearity,结构的保险丝的机制通过一个 single-degree-of-freedom 系统的韧性方程被调查,并且相应损坏减小光谱被建议设计并且翻新大楼。而且,控制参数,在主要框架之间的僵硬比率和结构的保险丝和主要框架的韧性因素,是参量地学习了,并且结构的保险丝概念能被控制参数的特定的联合基于建议损坏减小光谱完成,这被显示出。最后,一个设计例子和一个 retrofit 例子,在 2008 Wenchuan 地震以后的真实工程工程的变化,被提供用作为结构的保险丝弄弯制止的背带表明建议设计过程的有效性。
Recently, the structural fuse has become an important issue in the field of earthquake engineering. Due to the trilinearity of the pushover curve of buildings with metallic structural fuses, the mechanism of the structural fuse is investigated through the ductility equation of a single-degree-of-freedom system, and the corresponding damage-reduction spectrum is proposed to design and retrofit buildings. Furthermore, the controlling parameters, the stiffness ratio between the main frame and structural fuse and the ductility factor of the main frame, are parametrically studied, and it is shown that the structural fuse concept can be achieved by specific combinations of the controlling parameters based on the proposed damage-reduction spectrum. Finally, a design example and a retrofit example, variations of real engineering projects after the 2008 Wenchuan earthquake, are provided to demonstrate the effectiveness of the proposed design procedures using buckling restrained braces as the structural fuses.
