某噪声试验室由全消声试验室、浮筑基础、进排气消声装置及主体结构组成。其中全消声试验室为钢筋混凝土水平矩形筒体,通过浮筑基础支承在标高7.62m的一层楼板上,进气消声装置安装在屋盖网架结构中,排气消声装置通过设置夹层的结构方式安装在主体结构上。主体结构采用现浇钢筋混凝土框排架结构及钢网架屋盖,计算主体结构时对网架屋盖+进排气消声部分+下部结构进行整体分析,剖析了这一特殊复杂结构的受力特点并提出了简化的设计方法。为该类型试验室的结构设计提供了经验。
A noise laboratory consists of a full anechoic laboratory, floating foundation, intake and exhaust muffler and the main structure. Among them, the full anechoic laboratory is a reinforced concrete horizontal rectangular cylinder supported on a floor with a height of 7.62m through a floating foundation, the intake silencer is installed in the roof truss structure, and the exhaust muffler is installed The sandwich structure is installed on the main structure. The main structure is cast-in-place reinforced concrete frame and steel truss roof, the whole structure is analyzed when the main structure is taken into account. The analysis of the structure of this special complicated structure Force characteristics and proposed a simplified design method. This type of laboratory structure design experience.
