TGPSC HMWSSB Manager 2015 Paper 2 · Question 121
Question 121 of the TSPSC Manager (Engineering), HMWSSB, 2015: Paper 2 (Civil Engineering) (1 November 2015). Try it first, then open the answer and explanation.
For a simply supported girder, EUDLL is defined as the intensity of the UDL acting on full span whose ______.
- intensity is larger than all other loads acting on the span.
- moment diagram is above the bending moment ordinates caused by all loads on the span.
- bending moment diagram just envelops bending moment caused by all loads on the span.
- intensity is larger than the sum of intensities of all loads on the span.
Show answer
Answer: (3) bending moment diagram just envelops bending moment caused by all loads on the span.
The equivalent uniformly distributed live load (EUDLL) is the uniform load over the whole span whose bending moment diagram just envelops the maximum bending moments produced at every section by the actual moving loads. It lets girders and bridge decks be designed with one simple uniform load.
