［摘要］蘇州商服樓工程空中魚腹式鋼連廊的跨度為56.7m，距地高度為37.5、62.5m，如何確定鋼連廊的結構形式是一項設計難點。本文首先對三種方案的強度、剛度、經(jīng)濟性能進行了對比分析，最終確定下弦雙拉桿的剛接桁架結構作為鋼連廊的結構受力體系；其次對鋼連廊進行了構件設計、環(huán)狀剛片的平面外剛度分析、支座節(jié)點設計；最后進行了樓板舒適度性能評估，期望本文能夠為今后類似的工程設計提供參考和借鑒。
［關鍵詞］魚腹式； 鋼連廊； 張弦結構； 剛接桁架結構； 環(huán)狀剛片； 舒適度

Abstract: A fish-ellied steel gallery set in Suzhou Shangfu building project. The height of the steel gallery is 37.5m and 62.5m off ground, which span is 56.7m. How to determine the structure of steel gallery is complex in the design. In the first place, strength, stiffness and economic performance of three schemes were contrasted and rigid steel truss with steel rod was determined as a structure system of the fish-ellied steel gallery. Then, component was designed, stiffness out of plane was analyzed and the joint design of the steel gallery was presented. Lastly, comfort performance on floor was evaluated. This study is expected to provide reference for the similar engineering design.
Keywords: fish-ellied; steel gallery; beam string structure; rigid steel truss; ring rigidity piece; comfortableness
