摘要
某大跨项目,其屋面功能为体育活动中心,跨度为72m×101m。由于同时具备了大跨度和重载2个特点,本项目结构设计除了控制强度、刚度以外,控制大跨度屋盖震动引起的舒适度也是设计难点。论文详细介绍了屋盖的设计及舒适度分析的要点,并提供了设置调谐质量阻尼器(TMD)来控制屋盖舒适度的减振方案。
The roof function of a large-span project is a sports center with a span of 72 m ×101 m. Because of the characteristics of long-span and heavy load, in addition to the control of strength and stiffness, the control of comfort caused by large-span roof vibration is also a design difficulty. This paper introduces the key points of roof design and comfort analysis in detail, and provides a damping scheme of TMD to control the comfort of roof.
