台风作用下大型煤气柜动态响应的实测研究

Research on the Dynamic Responses of Large Gasholder Affected by Typhoon

煤气柜是一种重要的工业构筑物,可以存储几十万立方的煤气,其抗风性能直接关系到企业生产、居民生活和社会的安定。因此,开展煤气柜抗风研究有重要的工程意义。在台风"丹娜丝"影响我国期间,对某地一座30万m3的大型煤气柜进行了风致响应的现场实测研究,取得了风场以及结构响应的实测数据,讨论分析了该大型煤气柜各个主要部位的加速度响应,获得了煤气柜加速度响应沿柜体分布情况。所得实测分析结果具有较好的科学价值以及工程实用价值,可以为同类结构的抗风设计及相关研究提供参考。

There are close relations between wind resistant performance of the gasholder,which is an important industrial structure and can contain hundreds of thousands of cubic meters gas and the normal production in the enterprise,the normal life of the residents and even the social stability and safety.Therefore,conducting the research on wind resistance performance is of great importance in practical engineering.This research measures wind induced response characteristics of agasholder,which has a capacity of 300,000 cubic meters and is affected by the typhoon Danas.This paper analyzes the characteristic of the measured large-scale gasholder.It not only analyzes the acceleration responses of each key part of the gasholder,but also obtains the distribution of acceleration responses along the height of the gasholder according to the measured wind field and measurement data of structure response.The results of the filed measurement has scientific value and engineering practical value.And the results can be a reference for wind resistant design and relevant research of similar structures.
