Shelter Frame Analysis
The Shelter Frame Analysis begins with a shelter dimensional drawing from the client. The dimensional drawing is then converted into a three dimensional SolidWorks model. The three dimensional drawing is then saved into SolidWorks Simulation Beam Analysis, where the individual shelter frame members are converted into beam members, with the same material properties as the original shelter.
Wind load pressure is determined using methods outlined in AISC 7-05, chapter 6. These wind load pressures are then converted to wind load forces by multiplying these pressures by various shelter frame covering areas. A sample of these wind load pressure to wind load force calculations are shown on the bottom right of this page. The calculations were performed using Maple 16.
SHELTER FRAME SOLID MODEL AND STRESS PLOT
Shelter Frame Solid Model and Stress Plot Explanation
The image above shown a solid model and stress plot of a 52 ft x 40 ft shelter structure. The structure was modeled and analyzed with SolidWorks Simulation Beam Analysis software. A wind load of 120 mph at a direction 45 degrees relative to the structures roof ridge was used in the wind load analysis. The stress plot shown in the bottom image indicates that the maximum stress in the structure is about 32 ksi at the location indicated by the label on the stress plot.
