For flexural member service deflection limits, which approach best couples long‑term deformation checks with creep and shrinkage-aware analysis when Annex notes require it?
Choices
- (A) Instant construction deflection limits only
- (B) Ignore sustained load contributions for service criteria
- (C) Time-dependent service deflections using creep/shrinkage multipliers paired with permissible span/depth guidance
- (D) Reduce section depth blindly to meet deflection
Correct answer: (C)
Time-dependent service deflections using creep/shrinkage multipliers paired with permissible span/depth guidance
Explanation
Creep magnifies sustained-load deflections beyond elastic estimates.
