CELE Past Board Exam Problem
SITUATION 23: A 25 m long girder of a bridge is simply supported at the right end and at 3 m from the left end. It is subjected to a highway lane load consisting of a uniformly distributed load and a concentrated load as follows:
Uniformly distributed load = 9.35 kN/m
Concentrated load for moment = 80 kN
Concentrated load for shear and reaction = 115.7 kN
1. What is the maximum midspan positive moment (kN-m)?
2. Calculate the maximum support reaction (kN).
3. What is the maximum midspan negative moment (kN-m)?
