Experimental Study and Finite Element Analysis on Stress Transfer Mechanism of Retard-Bonded Prestressed Concrete Beams

In order to study the stress transfer mechanism of the retard-bonded prestressed concrete beams, a retard-bonded prestressed concrete beam is selected as the test monitoring object in the project site to find the stress change rule of the concrete in the monitoring process, and the stress transfer mechanism of the test beam concrete is obtained, which is compared with the traditional prestressed concrete structure. The finite element analysis software ANSYS is used to model the test beam, simulate the test beam in the stage of tension and bond hardening of slow binder, and compare with the test results. At the same time, simulate the stress of the test beam in the normal use process, analyze the dangerous section of the test beam and prevent in advance.
