Stress Analysis of Prestressed Foundation Construction Process of Long-span Slanted Brace Steel Structure
The long-span slanted steel structure is widely used in the conservation of large sites.Based on this,this paper studies the whole process of prestressed construction of steel structure foundation.It is found that the column foot will produce large horizontal thrust under the action of the structure's dead weight and construction load.Since the horizontal bearing capacity of the pile foundation is limited,prestressed foundation beams are installed between the pile caps to balance the horizontal load component of the superstructure.Simulation is used to analysis the construction of engineering examples to ensure that the stress of key components and the displacement of pile top are within the limit range.
