摘要
本工程集办公和展览于一体,且属于大悬挑、连体大跨结构,对楼盖系统的竖向振动引起的舒适度有要求,在设计中需对楼盖系统在人行激励下的振动特性和加速度进行验算。通过对本工程进行楼板舒适度分析,结果表明:楼盖在随机人群行走、小部分原地踏步、小部分人群齐步前进、小部分人群原地跳跃工况下办公区竖向加速度时程最大值不超过0.05m/s^2,展览区及室内连廊的竖向加速度时程最大值不超过0.15m/s^2,结构满足国家规范《高层建筑混凝土结构技术规程》(JGJ 3—2010)中对楼盖结构舒适度的要求。
The Guizhou Geological archives and Geological museum is a combination of office and exhibition,the building is large cantilevered,large-span connective structure,it is necessary to check the vibration characteristics and acceleration of the floor system under human walking in the design stage. According to the result of the floor vibration serviceability analysis on the project,it is indicated that the maximal acceleration of exhibition and indoor corridor of the building is not more than 0. 15 m/s^2 under a small part of the crowd random walking,marching and jumping conditions,the result reached the demands of floor vibration service ability in the Chinese code of Techinical specification for concrete structures of tall building( JGJ 3—2010).
