摘要
为了研究某高铁客运站进站口玻璃幕墙结构动力安全性,采用几何比尺为1∶1的整体结构模型,对该新型结构形式下的带减振装置的玻璃幕墙结构进行了风压准静载和动力试验研究.结果表明:在风压达到设计风压1.4kPa时,幕墙玻璃面板最大应力仅为21.49MPa,强度储备大,受力安全;幕墙不存在低频大幅振动的可能,结构动力特性设计合理.幕墙振动比零风压时要大,双边激振对结构不利.
In order to study the glass curtain wall structure dynamic security of a high-speed railway station entrance,a model of 1∶1 scale was adopted;for the overall structure of the model of the new structure,with the form of reducing vibration device glass curtain wall structure,the static load and wind pressure dynamic test have been carried out.The results show that in the wind pressure distributions of 1.4 kPa of the design pressure,the curtain wall glass panel maximum stress is only 21.49 MPa;the strength and the structural safety is sufficient;there are large reserves of curtain wall;and a low frequency vibration of structural dynamic characteristics does not exist.The design is reasonable.Curtain wall＇s vibration is larger than zero wind pressure,bilateral vibration to the structure is adverse.
