Questions and Answers

What is the purpose of placing a counterweight at the end of the structure (abutment 1) just before the launching nose reaches pier 2?

  • To increase the speed of launching
  • To ensure stability and safety against overturning of the structure (correct)
  • To test the strength of the bridge beams
  • To reduce the weight of the structure

    • What factor has a significant influence on the distribution and magnitude of the moments during launching?

  • The type of steel used in construction
  • The distance between abutment 1 and abutment 2
  • The length of the launching nose (correct)
  • The presence of counterweights

    • Why are the states of stress during launching different from those experienced by the bridge beams in their final state?

  • Due to the choice of the launching nose (correct)
  • Due to the influence of the counterweight
  • Due to the type of steel used
  • Due to the presence of pier 2

    • Why should the length of the launching nose be chosen carefully?
