隔震支座的选取原则

The Selection Principle of Isolation Bearing

隔震装置的类型、数量和规格是隔震结构的关键技术要素。隔震装置的选取应最大限度的提高隔震能力与效率,并兼顾隔震综合性价比。根据工程经验,文章系统地阐述了隔震支座的水平刚度、水平变形能力、耗能、制作、检测、安装、相关结构以及性价比等问题,提出了隔震装置选型的6项基本原则。可用于指导选取隔震装置,提高隔震技术水平。

The type, quantity and specification of isolation devices are the key technical factors of isolated structures. The election of isolation devices should maximize the isolation capacity and efficiency, and take into account the comprehensive performance cost ratio of isolation. According to the engineering experience, this paper systematically describes these subjects about horizontal stiffness, horizontal deformation capacity, energy dissipation, detection,manufacturing, installation, the influence of the structure and price and other technical and economic.. Six basic principles for selection of isolation devices are put forward. It can be used to guide the selection of isolation devices and improve the isolation technology level.
