Why do placing drawings stagger horizontal lap splice zones in shear walls?
Choices
- (A) Purely for graphic neatness
- (B) Avoid plane sections where every bar laps at identical elevation weakening strain transfer bandwidth
- (C) To arbitrarily shorten protective cover notes
- (D) To eliminate tie-wire requirements entirely
Correct answer: (B)
Avoid plane sections where every bar laps at identical elevation weakening strain transfer bandwidth
Explanation
Staggered laps spread weakness over height rather than plane bands.
