［摘要］重慶江北國(guó)際機(jī)場(chǎng)航站樓主樓單索幕墻結(jié)構(gòu)面積近10 000m2，并且一側(cè)長(zhǎng)度達(dá)到180m。其索網(wǎng)的支撐結(jié)構(gòu)體系較柔，索網(wǎng)幕墻體系超長(zhǎng)，給設(shè)計(jì)和張拉施工方案的制定都帶來(lái)了較大難度。將屋面鋼結(jié)構(gòu)體系與幕墻結(jié)構(gòu)體系整體建模，兩者之間通過(guò)耦合實(shí)現(xiàn)水平聯(lián)系，同步加載進(jìn)行結(jié)構(gòu)設(shè)計(jì)，以此考慮屋面鋼結(jié)構(gòu)對(duì)幕墻體系的影響。進(jìn)行了超長(zhǎng)幕墻結(jié)構(gòu)體系跨越下部結(jié)構(gòu)伸縮縫的受力分析，并得出由于柔性結(jié)構(gòu)很強(qiáng)的變形適應(yīng)能力，下部結(jié)構(gòu)伸縮縫不會(huì)對(duì)幕墻結(jié)構(gòu)體系產(chǎn)生破壞作用的結(jié)論。拉索幕墻的張拉方案必須與設(shè)計(jì)思路相互一致。對(duì)該超長(zhǎng)單索幕墻張拉方案的原則也進(jìn)行了介紹。

Structure design of over-length single-layer cable-net curtain wall of Chongqing Jiangbei International Airport Liu Feng1, Ma Hongrui1, Zhao Xiaohua1, Zhao Pengfei1, Zhang Gaoming1, Ma Hongxu2, Yang Zhigang2(1 China Academy of Building Research, Beijing 100013, China; 2 Beijing Jangho Curtain Wall Co., Ltd., Beijing 101300, China)Abstract:The area of single-layer cable-net curtain wall of the main airport building of Chongqing Jiangbei International Airport is about 10 000m2, whose length for one side is 180m. The supporting structure system for the cable-net is flexible, and the curtain wall is overlength, which brings difficulties to the design and pre-stress construction plan. The whole model including roof steel structure and curtain wall system was established, and  the relationship between roof and curtain wall was realized through horizontal coupling. The  curtain wall structure was designed by loading synchronously on the whole model,  which can consider the influence of the steel roof on the curtain wall system. At the same time, the force analysis of over-length continuous curtain wall system across the expansion joints of substructure was carried out. The conclusion is made that the curtain wall system will not be damaged by continuous design because of the adaption to deformation of flexible structure. The pre-stress construction plan must be in accord with the design concept. The principles of pre-stress construction plan from design angle were also introduced.
Keywords:single-layer cable-net; structural design; expansion joint; pre-stress construction plan
