［摘要］由于影劇院、禮堂等建筑的臺口跨度較大，普通鋼筋混凝土臺口梁的強度、裂縫和撓度很難滿足設計要求，利用舞臺與觀眾廳之間的空間設置鋼筋混凝土桁架，能有效解決臺口跨度大造成的結構難題。結合兩個工程設計實例，論述了采用SATWE計算軟件對含有鋼筋混凝土桁架的結構進行整體分析的合理性和適用性；給出了建立計算模型時桁架的弦桿、腹桿、斜桿以及樓板采用的計算單元；分析了桁架端部斜桿設置、弦桿斷面、腹桿間距等因素對桁架內(nèi)力分布的影響；提出了設計中應采取的構造措施和施工工藝。
［關鍵詞］鋼筋混凝土桁架；臺口梁；彈性膜

Design and application of reinforced concrete truss

Abstract:The strength, crack and deflection of common reinforced concrete beams can hardly meet the design requirement because the proscenium opening span of cinema and auditorium buildings is large. Reinforced concrete truss which is located in the space between stage and audience hall can effectively solve the structure problem caused by large span of proscenium opening. Based on two practical engineerings, the rationality and applicability of total analyses by SATWE of the structure with reinforced concrete truss were discussed. The computation elements of chord member, web member, diagonal member and slab adopted in the computation model were given. The truss internal force distribution influenced by diagonal member setting in truss ends, chord member section and web member space was analyzed. The details of construction measures and construction technology in design were proposed.
Keywords:reinforced concrete truss； proscenium opening beam； elastic membrane
