(北京四維新建筑科技開(kāi)發(fā)中心 100089)[提要] 主次梁樓蓋體系是結(jié)構(gòu)設(shè)計(jì)時(shí)常用的。對(duì)主次梁樓蓋設(shè)計(jì)中如何合理布置柱網(wǎng)和選擇主、次梁,在框架彈性受力分析和承載力計(jì)算時(shí),應(yīng)如何考慮整澆板的共同工作效應(yīng)等問(wèn)題,作者作了概念對(duì)比和探討,可供設(shè)計(jì)人員參考。
[關(guān)鍵詞] 結(jié)構(gòu)體系 主次梁 框架 翼緣寬度 塑性鉸線 長(zhǎng)度The rational layout of columuns and selection of girders and joists in design of horizontal subsystems, and the consideration about the effect of composite action with casted slab in elastic analysis and strength calculation of framed beams, etc. are discussed with conceptual contrast.
Keywords: horizontal subsystems; joist-girder; frame; flange width; inelastic hinge lengths
