About this file

These are structural engineering calculations for a caisson footing for a canopy column at a project located at 5201 Raymond Street in Orlando, Florida. The documents, prepared by Simply Structural Inc. in December 2023, include detailed wind load analyses and pole footing embedded soil calculations using the 2018 IBC, 2019 CBC, and ASCE 7-16 standards. Key technical specifications include a circular 18-inch diameter caisson with an 18-foot column height, wind load of 0.810k, and an assumed soil allowable bearing pressure of 1,500 psf. The calculations evaluate various load combinations and demonstrate that the proposed footing design meets structural engineering requirements, with a minimum required embedded depth of 4.625 feet and a maximum soil pressure of 0.8403 ksf.

NOTE: 1). Cnw and Cnl denote combined pressures from top and bottom roof surfaces.

2). Cnw is pressure on windward half of roof. Cnl is pressure on leeward half of roof.

3). Positive pressures act toward the roof. Negative pressures act away from the roof.
