In a two-way restrained slab (IS 456 Table 26), all four edges fixed, the negative (hogging) moment at the fixed edge is computed using:
Choose the correct answer
The same α coefficient as mid-span positive moment
A different (larger) coefficient α' > α
Zero (fixed edges are moment-free)
The coefficient from simply supported condition
Correct Answer
B. A different (larger) coefficient α' > α

IS 456 Table 26: The hogging moment coefficients α'_x and α'_y at fixed edges are larger than the sagging moment coefficients α_x and α_y at mid-span, reflecting higher moments at restrained edges.
