Concrete Technology & RCCM20 maximum shearMEDIUM
Choose the correct answer
A
3.5 N/mm2
B
1.2 N/mm2
C
2.8 N/mm2
D
5.0 N/mm2
Correct Answer
C. 2.8 N/mm2
Why is this the answer?
IS 456 Table 20 gives tau_c,max for M20 as about 2.8 N/mm2. Reference: Clause 40.2.3; Table 20 | Page: verify from your official BIS copy/PDF pagination
