[摘要]大連市體育場看臺(tái)結(jié)構(gòu)為混凝土框架結(jié)構(gòu),上層看臺(tái)徑向兩端為關(guān)鍵節(jié)點(diǎn),一端是罩篷鋼桁架上部支座的支承結(jié)構(gòu),一端是大懸臂結(jié)構(gòu)。著重闡述了這兩個(gè)節(jié)點(diǎn)的結(jié)構(gòu)方案分析及設(shè)計(jì)。上層看臺(tái)混凝土結(jié)構(gòu)環(huán)向超長,為了控制溫度應(yīng)力和混凝土收縮所產(chǎn)生的裂縫采取了設(shè)置粘結(jié)預(yù)應(yīng)力筋、施工后澆帶、通長板鋼筋等一系列措施。并應(yīng)用MIDAS Gen程序進(jìn)行總裝整體模型計(jì)算,考慮了240余種荷載組合,選取了最不利荷載進(jìn)行結(jié)構(gòu)設(shè)計(jì)。

Abstract:The upper grandstand of Dalian Stadium is reinforced concrete structure, and the radial ends of this grandstand are key nodes, one is the support structure for top pedestal of the ceiling structure, and the other is long span cantilever. The structural analysis and design of these two nodes were summarized. The upper grandstand is super-long structure in radial direction. A series of measures, such as setting bond prestressed reinforcement, pouring techninque after construction and reinforced through whole plates, were adopted to reduce cracks caused by temperature stress and concrete shrinkage. MIDAS Gen finite element software was used to perform whole structure analyses, 240 load combinations were checked and the most adverse load was select to be the design load.
Keywords:stadium; supporting structure; member with pull and press; bonded prestress; super-long structure
