TGPSC HMWSSB Manager 2015 Paper 2 · Question 142
Question 142 of the TSPSC Manager (Engineering), HMWSSB, 2015: Paper 2 (Civil Engineering) (1 November 2015). Try it first, then open the answer and explanation.
According to IS: 456-2000, in the design of isolated RCC column footing using RCC with an effective depth d, the critical sections to be checked are ______.
- Bending moment at the face of the column, one-way shear at d/2 away from the face of column and two-way shear at d around the column.
- Bending moment at the face of the column, one-way shear at d away from the face of column and two-way shear at d around the column.
- Bending moment at d/2 away from the face of the column, one-way shear at d away from the face of column and two-way shear at d/2 around the column.
- Bending moment at the face of the column, one-way shear at d away from the face of column and two-way shear at d/2 around the column.
Show answer
Answer: (4) Bending moment at the face of the column, one-way shear at d away from the face of column and two-way shear at d/2 around the column.
IS 456:2000 (cl. 34.2.3.2 and 34.2.4.1) takes the critical section for bending at the face of the column, for one-way shear at a distance d from the column face, and for two-way (punching) shear on a perimeter at d/2 from the column face.
