Experimental and Analytical Study of Prestressed Steel–Concrete Composite Beams Considering Slip Effect
Publication: Journal of Structural Engineering
Volume 133, Issue 4
Abstract
This paper investigates the behavior of simply supported prestressed steel–concrete composite beams through experimental and analytical studies. Eight specimens were instrumented and tested in the experimental program considering different parameters. The slip effect between the steel and concrete interface and the increase of the prestressing tendon force with the increase of loading were accounted for in the analytical model. A reduced stiffness method was then proposed for calculating the deflection of prestressed composite beams. Formulas for calculating the yield and ultimate moments were also derived. It was found that including the slip effect on the deflection and yield moment can significantly improve the accuracy of analytical predictions. As the calculated values showed good agreements with the test results, the proposed formulas can be reliably applied to the analysis and design of prestressed steel–concrete composite beams.
