An Accurate Calculation Method for Erecting Curves of Wire Strands of Long Suspension Bridges

  • Publish Date: 25 Jun 2001
  • According to the conditions and practices of suspension bridge erection, a method is proposed for accurate calculation of erecting curves of wire strands of long suspension bridges. By analyzing the conditions of equilibrium on the saddleswhile the wire strands are being erected, the theoretical calculation method of the pre-displacement, which is the desired position of saddles, is developed. The proposed method takes the non-linearity of the wires into consideration, avoids the errors resulted by suppositions in finite element method, and is more accurate than finite element method.
