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.

SolidWorks Beam Analysis

You can simplify structural beams to optimize performance in Simulation to be modeled with beam elements. The size of the problem and the resources required are dramatically reduced in this case.

For the beam formulation to produce acceptable results, the length of the beam should be 10 times larger than the largest dimension of its cross section.
