| Abstract: | This article describes the engineering practice of a super high-rise steel construction with 43 aboveground floors and 5 underground floors,the pit excavation depth is 22m-28.7m.The tower and underground structure are constructed at the same time,using top-down method,the basement floors are used as horizontal strut of the pit.The steel trusses are used in the region without floor.The ANSYS software is used to analyse the floor reinforcement.Monitoring data show that: the top-down method can effectively pro... |
