4. FIELD DOCUMENTATION

5. INSURANCE RECORDS RELATIONSHIP BETWEEN LOSS MAGNIFIER AND GRADIENT WIND SPEED

6. COMPUTER MODELS (HAZUS) The hazus model computes damage caused by hurricane events to buildings In specified regions Thousands of possible damage scenarios are considered for each building type In most cases damage costs exceed total insured value before The principal structural frame fails

7. STRUCTURAL INTEGRITY: VERTICAL LOAD PATHS MEMBRANE INSULATION METAL DECK JOIST ADHESIVE WELD WALL BOLT FORCES ACROSS CONNECTIONS

8. STRUCTURAL INTEGRITY: HORIZONTAL LOAD PATHS GLASS PLATE HEAD SILL SECONDARY FRAMING WINDOW FRAME SCREWS OR BOLTS BOLTS OR WELD SCREWS OR BOLTS BOLTS OR WELD WIND PRESSURE

9. FINANCIAL CONSIDERATIONS LOSS OF BUSINESS Business interruption Loss of market share LOSS OF FACILITY Loss may exceed insured value Replacement costs may disrupt business plan

10. PEOPLE CONSIDERATIONS INJURY OR DEATH EMOTIONAL DISTRESS COMMUNITY DISRUPTION
