Civil Engineering QUESTION #6612
Question 1
In the design of base plates for columns, the 'equivalent cantilever' length $l$ is used to determine the plate thickness. This length is usually calculated from:
  • The distance from the column face to the edge of the base plate✔️
  • The distance between the anchor bolts
  • The total length of the base plate
  • The radius of gyration of the column
Correct Answer Explanation
Base plate thickness is determined by treating the portions of the plate extending beyond the column profile as cantilever beams loaded by the bearing pressure from the concrete foundation.
