9 Inputs for Surge + Wave Vulnerability Significant Wave Height Surge Elevation House Age (in ranges of years) Lowest Horizontal Structural Member Elevation
10 Damage Module Input Hazard Time Histories Wind Surge + Wave Construction Features Output Time of probable collapse from surge + waves Time Histories of component damage due to wind
11 Demonstration of Methodology: Site Surviving Structure Slab-only Structure
12 Pictometry™: Aerial View Before Ike
13 Pictometry™: Aerial View After Ike
14 Current Model Inputs Roof shape: Gable Roof cover type: Asphalt Shingle Roof slope: 4:12 Roof height: 20 ft. Roof cover age: 9 years Length: 42 ft. Width: 34 ft. Eave height: 17 ft.
15 Current Model Inputs (cont.) Structure primary axis: 60° Terrain exposure: D Overhead garage door: Yes Direction of garage door: 240° Garage panel door width: Single Garage attached: Yes Percent window area: 0-25 Elevation of Lowest Horizontal Structural Member: ft. Year Built: 1999
16 Damage Module Construction Features: Surviving Structure Slab-Only Structure
17 Damage Module Surviving Structure: Time of Probable Collapse ft.
18 Damage Module Slab-Only Structure: Time of Probable Collapse ft.
19 Damage Module Surviving Structure: Component Damage Time Histories
20 Damage Module Slab-Only Structure: Component Damage Time Histories Point where structure topples over.
25 Results Slab-Only Structure: Roof Cover Damage Variation with Height and Exposure
26 Ongoing Work The model will include a provision for variations in component resistance, for example: vinyl siding vs. fiber cement siding; shingles vs. metal roof; etc. At the request of TDI the Panel is working to include these and other component variations into the model before its first release in 2015.
