摘要: 中南大學(xué)新校區(qū)體育館主體結(jié)構(gòu)采用鋼筋混凝土框架結(jié)構(gòu),屋蓋的最大跨度為 92. 1m,采用空間鋼管桁架結(jié)構(gòu),具有較好的整體穩(wěn)定性. 屋蓋桁架跨度大,溫度作用明顯,為減小溫度變化對(duì)結(jié)構(gòu)造成的不利影響,鋼結(jié)構(gòu)屋蓋與混凝土框架柱之間通過(guò)鋼管轉(zhuǎn)動(dòng)柱及固定鉸支座組成節(jié)點(diǎn)連接,該連接方式使得桁架在因溫度變化而產(chǎn)生水平向伸長(zhǎng)或縮短時(shí),鋼管轉(zhuǎn)動(dòng)柱通過(guò)一定角度的傾斜,以適應(yīng)屋蓋桁架的伸縮變形,從而實(shí)現(xiàn)屋蓋桁架溫度應(yīng)力的釋放,提高了整體結(jié)構(gòu)的承載能力. 考慮結(jié)構(gòu)特點(diǎn)及場(chǎng)地條件,采用累積滑移施工. 對(duì)施工過(guò)程進(jìn)行模擬分析并將桁架應(yīng)力及撓度的監(jiān)測(cè)值與計(jì)算值進(jìn)行對(duì)比,結(jié)果表明滑移施工過(guò)程安全可靠.

Abstract: The main structure of the gymnasium on the new campus of Central South University adopts a reinforced concreteframe structure. The maximum span of the steel roof is 92. 1m, and spatial pipe truss structure is adopted, which has goodoverall stability. The roof truss has a large span and the temperature effect is obvious. In order to reduce the adverse effectsof temperature changes on the structure, the steel structure roof and the concrete frame column are connected by a jointconsisting of a steel pipe rotating column and a fixed hinged support. The connection method makes the steel pipe rotatingcolumn tilt at a certain angle to adapt to the expansion and deformation of the roof truss when the truss is stretched orshortened horizontally due to temperature changes, so as to release the temperature stress of the roof truss and improve thebearing capacity of the whole structure. Considering the structural characteristics and site conditions, the cumulative slidingconstruction was adopted. The construction process of the roof slip construction was simulated and analyzed, and themonitoring values of truss stress and deflection were compared with the calculated values. The results show that theconstruction process is safe and reliable.

Keywords:large-span spatial structure; steel pipe truss; thermal stress; bearing joint; sliding construction
