Questions and Answers

What is the primary reason for using cantilever erection for bridge construction?

  • To reduce the need for temporary supports
  • To simplify the process of joining bridge pieces
  • To minimize the weight of the bridge elements
  • To allow for construction over navigable waterways (correct)

    • Why is significant and accurate precambering necessary for cantilever bridge construction?

  • To compensate for the deflections of the cantilevers under their own self-weight (correct)
  • To facilitate the lifting of bridge elements into position
  • To reduce the stress on the steel structure during construction
  • To prevent wind from affecting the cantilevered sections

    • What type of bridge girders are better suited to cantilever erection?

  • Composite girders
  • Solid steel girders
  • Open U shaped box
  • Closed box section (correct)
