［摘要］某噪聲試驗室由全消聲試驗室、浮筑基礎(chǔ)、進(jìn)排氣消聲裝置及主體結(jié)構(gòu)組成。其中全消聲試驗室為鋼筋混凝土水平矩形筒體，通過浮筑基礎(chǔ)支承在標(biāo)高7.62m的一層樓板上，進(jìn)氣消聲裝置安裝在屋蓋網(wǎng)架結(jié)構(gòu)中，排氣消聲裝置通過設(shè)置夾層的結(jié)構(gòu)方式安裝在主體結(jié)構(gòu)上。主體結(jié)構(gòu)采用現(xiàn)澆鋼筋混凝土框排架結(jié)構(gòu)及鋼網(wǎng)架屋蓋，計算主體結(jié)構(gòu)時對網(wǎng)架屋蓋+進(jìn)排氣消聲部分+下部結(jié)構(gòu)進(jìn)行整體分析，剖析了這一特殊復(fù)雜結(jié)構(gòu)的受力特點并提出了簡化的設(shè)計方法。為該類型試驗室的結(jié)構(gòu)設(shè)計提供了經(jīng)驗。

Abstract:The acoustical testing facility is cast-in-situ reinforced concrete frame/bent frame structure and steel lattice grids roof are used as the main structure. In calculating the main structure, lattice grids roof and air intake/exhaust muffler and substructure have been analyzed as a whole. Load bearing characteristics and simplified design approach of such sophisticated structure have been summarized, providing precious experience with respect to the structure design involved in this kind of testing facility.
Keywords:acoustical testing facility; floating foundation; acoustical structure; vibration insulation
