Abstract: By designing a 20m span transfer structure case, the comparison and optinuzation of the transfer truss project is introduced. The analysis of the prestress components design and construction is done. The method of prestressed transfer truss structure could be consulted in correlation design.
Keywords: transfer truss; prestressed concrete; prestress loss; crack check; post-tensioning method
