Q: Consider the following conditions. 1. Concentrated loads are placed near beam supports. 2. The depth of beam section is small, and the beam is loaded uniformly. The design of a beam is governed by shear under which of the following conditions?
  • A. Neither 1 nor 2
  • B. 2 only
  • C. Both 1 and 2
  • D. 1 only
Correct Answer: Option C - Shear determines design of beam when depth of beam section is small and loaded uniformly, when large concentrated loads are placed near beam support, when two members are rigidly connected together. With their webs lying in same plane, when web thickness is small in plate girders.
C. Shear determines design of beam when depth of beam section is small and loaded uniformly, when large concentrated loads are placed near beam support, when two members are rigidly connected together. With their webs lying in same plane, when web thickness is small in plate girders.
