Direction: A two span continuous beam having equal spans each of length L is subjected to a uniformly distributed load w per unit length. The beam has constant flexural rigidity.
-
The reaction at the middle support is
-
- wL
- 5wL/2
- 5wL/4
- wL2/16
Correct Option: C
When support C is removed
| δL = | ||||
| 384 | EI |
Actual
| δL = | 48EI |
By compatibility equation,
| = | ||||||
| 384 | EI | 48EI |
| ∴ R = | 4 |
