Abstract

According to the equilibrium condition of geometry relationship, we derived the formulas that can be used to calculate the loss of prestress of prestressing tendons with the double-end tensioning and the asymmetrical arrangement parabolic curves. Through an example of the bridge engineering, we described in detail the complete procedure of the proposed formula method, and it is shown that the proposed method is simple and practical. Comparing with the Midas software method would prove to be accurate. This work could be used to calculate the losses of prestress for 2-dimensional parabolic prestressing tendons.
