Static Load Test And Numerical Analysis Analysis Of Prestressed Concrete Beams

Prestressed concrete could combine the high strength of reinforced bar with the high strength of concrete dynamically. As a result the prestressed concrete has been used in the fields of construction engineering, bridge and traffic engineering, hydraulic engineering and special structure. Prestressed concretes simple supporting the T-beam bridges becomes one of the widely-used type of bridges in railway bridge constructions in China because of its benefits. With the rapid development of economy, the traffic is increasingly rising, and the load grade increases incessantly, while people demand safer driving.The paper, based on 32m prestressed concrete simple T-beam, makes a research of monotone static test. The rational mechanical model is established with MIDAS/CIVIL. Taking into account the influence of loss of prestress, constructing process is simulated, and loading Procedures is tested. Numerical analysis is maked. The results are compared, and some conclusions are drawn.According to the test and mechanical analysis in this paper, one may find some valueable references to the design and construction and reinforcement maintenance of prestressed concrete bridge in the future.
