(浙江大學(xué) 杭州 310027)[提要] 系統(tǒng)詳盡地介紹了折板網(wǎng)殼的基本造型、結(jié)構(gòu)形式和支承方式,并對設(shè)計、施工中需注意的要點做了說明。針對四邊形正交正放四角錐折板網(wǎng)殼進行了自振特性計算,并進行了參數(shù)分析,研究了當(dāng)結(jié)構(gòu)厚度、屋面坡度以及支承方式等發(fā)生變化后對這種結(jié)構(gòu)動力性能的影響,為工程人員全面地把握折板網(wǎng)殼的設(shè)計提供了依據(jù)。
[關(guān)鍵詞] 折板網(wǎng)殼 空間結(jié)構(gòu) 動力性能Hy-rib pyramid lattice shell synthesizes the merits both of spatial truss and lattice shell, so it will be widely applied in practical projects. The configuration and geometric composition of hy-rib pyramid lattice shell are introduced. Moreover, the dynamic properties are analyzed considering the influence of the different thickness or degree of shell, different support structure. Some valuable conclusions are obtained, which can provide a reference to civil engineering.
