摘要
阻尼器不仅可以减轻结构震害,也可以用于结构抗震体系的优化。本文针对某工程实例,综合考虑建筑的功能要求和结构的抗震要求,用减震框架结构代替配置少量剪力墙框架结构。通过有限元软件分别建立了上述两种结构类型模型,对二者进行了多遇地震弹性和罕遇地震弹塑性变形分析。结果表明,与配置少量剪力墙框架结构相比,减震框架结构具有更好的抗震性能和经济优势,在结构抗震体系优化选型中具有较好的应用前景。本文研究成果已应用于该工程的结构抗震体系选型。
Damper can not only reduce earthquake damage, but also be applied in structural seismic optimization selection. Considering the requirements of architecture function and aseismic performance, in a certain engineering case, frame-shear structure is replaced with damping-frame. The two types of structural models are established through finite element software. Frequently and rarely occurred earthquake elastic-plastic deformation analysis are conducted. Compared with frame-shear structure, damping-frame structure has better aseismic performance and economic advantages. It has great application foreground in structural selection and optimization. The results have been applied to the seismic system selection of this structure.
