| Abstract: | The multi-storey 24 m span vierendeel trusses are the key structures to control due operations of the Beijing Zhuangsheng Square Central Building.Therefore,all deflections of these vierendeel trusses must be strictly controlled within their design' s allowable limit.To achieve these goals,measures of adopting steel pipe scaffoldings for constructions of 60 000 kN vierendeer trusses shoring members,have been proved successful to control their lateral displacements. |
