［摘要］徐州某物流園區(qū)在兩棟結(jié)構(gòu)體系完全不同的塔樓間設(shè)置了大跨度鋼連廊，大跨度鋼連廊縱向柱間跨度為49-5m、橫向柱間跨度為16-8m，并帶有較大長(zhǎng)度的懸挑端。采用鋼桁架與樓面鋼梁的結(jié)構(gòu)形式，通過可滑動(dòng)的球形鋼支座實(shí)現(xiàn)連廊與兩端主體結(jié)構(gòu)的連接，保證了連廊本身的強(qiáng)度與剛度。并按規(guī)范要求控制樓蓋的豎向振動(dòng)加速度，確保了支座與支承柱的可靠連接。

Abstract:Large-span steel gallery is set between the two towers with completely different structural systems in a  logistics park in Xuzhou. The longitudinal column spacing of the large-span steel gallery is 49-5m, and transverse column spacing is 16-8m, and there are cantilever structures with large-length. The structural form of steel truss and floor steel beam is adopted and the connection between the gallery and the main structure at the two ends is realized through the sliding spherical steel bearing, which ensures the strength and stiffness of the gallery. And the vertical vibration acceleration of floor is controlled according to the specification to ensure reliable connection of the bearing and the supporting column.

Keywords:large-span steel gallery; steel truss; sliding bearing
