摘要:本文以宁波奥体中心游泳馆项目为研究背景, 针对项目存在的大跨度楼盖的振动舒适度问题, 进行了大跨楼盖舒适度的分析和设计。建立了楼盖的有限元模型, 分别考虑了人行走、跑动和跳跃等工况; 采用时程分析法求得结构在各工况下的加速度响应; 同时采用ATC给出的人不同环境下人舒适度所能接受的峰值加速度水平作为该项目的舒适度评价标准。计算结果表明本项目的大跨度楼盖具有适宜的刚度和舒适度。本文采用的计算分析方法及评价标准对同类型大跨度楼盖的舒适度分析具有一定的参考价值。

Abstract: This paper takes Ningbo Olympic sports center swimming pool project as the research background for large span floor vibration comfort problems of the project, has carried on the analysis and design of long-span floor comfort. Floor of the finite element model is established, considering the working condition of walking, running and jumping, etc. Using time history analysis method for structure under various operating conditions on the acceleration response. Use of ATC is given at the same time would be acceptable to different environmental human comfort horizontal peak ground acceleration as the comfort evaluation standard. The calculation results show that the objective of the large-span floor with appropriate stiffness and comfort. This paper uses the calculation method and evaluation standard of comfort analysis of the same kind of large span floor has a certain reference value.
