Experiment and Numerical Simulation on Non-Magnetic Prestressed Beam

Abstract:

In order to meet demanding of non-magnetic, changing the reinforcement ratio, the degree of prestress and cross section form, four partially prestressed concrete beam (3 T shape section, 1 rectangle section) were made with CFRP as longitudinal reinforcement and stirrup. The results show that: the pure bending sections of the test beams conform the plane-section assumption; the beams with bigger rate of reinforcement or with stronger prestress tends to appear more cracks with smaller spacing and width, also their cracking load were higher with relatively lesser deflection. The cracking load and ultimate load of T-shape beam are slightly larger than the rectangular beam’s, but their deflections are similar nearly. Based on experimental research, nonlinear finite element analysis software ANSYS was utilized to establish the model, the results of numerical simulation and experiments showed good agreement.
