Definitions, symbols, and general requirements
4. Flood & Tsunami Loads (Chapter 5 & 6)
- Sea Level Rise Adjustment Factor: A mandatory multiplier for coastal flood mapping (first time in ASCE 7 history).
- Tsunami-Resistant Design: Expanded from a commentary section to a mandatory chapter for high-occupancy coastal structures.
- Dead loads: clarified treatment of permanently attached equipment.
- Live loads: updated occupant, storage, and roof live loads; clearer rules for load reductions.
- Rain loads: detailed procedures for determining ponding/rain-on-roof and rain-on-snow; introduces simplified checks and more rigorous analyses where needed.
- Roof drainage and overflow requirements addressed.
