New solution method for steady-state canopy structural loads

Abstract

A new computer code has been written to perform structural analysis of canopies. Although an existing code, CANO, has been available, the new code has better convergence reliability, is more understandably written, and is easier to use. The equations have been reformulated for the new solution method. The new code assumes a symmetric canopy, a steady-state condition, and no strength in the vertical direction. It computes the inflated shape, loads in the horizontal members, radial members, vent lines, suspension lines, and total drag. Constructed geometry, material properties, dynamic pressure, and pressure distribution are required as input.
