Decision analysis for storage of prefabricated T-beam beyond the expiry date
The long-term storage of 40 m prestressed concrete prefabricated T-beam,generate the arch.The structural strength and stiffness of T-beam are verified through the static load test of a single beam and the measured deformation,stress and cracks of the beam body.It provides the basis for the decision of the use of the prefabricated T-beam.
