Site Investigation of a Prestressed Concrete Slab -Concrete Strength,Deformation and Other Tolerance Data.

摘要

A study was made of construction tolerances,material behavior and design values of a prestressed concrete slab in Sydney. The design requirement was for a low level of two-way prestress (2.76MPa) to be applied at an early age (the stressing was performed in stages,the first stressing taking place at 2days). The design layout of stressing tendons was compared with the actual site profiles.
