【摘要】：國(guó)家會(huì)展中心E1單體,地上7層,地下1層。由于地鐵從其中心穿過,地下室被地鐵線路一分為二,上部結(jié)構(gòu)的最大轉(zhuǎn)換跨度為117m,轉(zhuǎn)換區(qū)域存在的彎矩、扭矩與剪力使得結(jié)構(gòu)的受力極為復(fù)雜,設(shè)計(jì)難度大。經(jīng)過方案比選,結(jié)構(gòu)設(shè)計(jì)采用了帶屈曲約束鋼板墻的框架-支撐筒體結(jié)構(gòu),通過巨型的轉(zhuǎn)換箱形曲梁實(shí)現(xiàn)大跨度跨越地鐵,采用輕骨料混凝土減小了轉(zhuǎn)換區(qū)域的荷載。由于施工期間,地鐵需保持正常運(yùn)營(yíng),結(jié)構(gòu)設(shè)計(jì)與施工采取了多項(xiàng)措施來滿足地鐵運(yùn)行的維護(hù)保養(yǎng)要求;采用整體結(jié)構(gòu)的縮尺靜力荷載試驗(yàn)驗(yàn)證了結(jié)構(gòu)設(shè)計(jì)的可靠性。
[Abstract]:National Convention and Exhibition Center E1 single unit, above ground 7 stories, underground 1. As the subway passes through its center, the basement is divided into two by subway lines, the maximum span of the superstructure is 117 m, and the bending moment exists in the conversion area. Torque and shear force make the force of the structure very complicated and difficult to design. Through the scheme comparison and selection, the frame-support tube structure with buckling constraint steel plate wall is adopted in the structure design, and the large-span subway is realized through the giant transfer box curved beam. Lightweight aggregate concrete is used to reduce the load in the transfer area. Due to the need to maintain the normal operation of the subway during the construction period, many measures have been taken in the structural design and construction to meet the maintenance requirements of the subway operation. The reliability of the structural design is verified by the static load test on the scale of the whole structure.
