The document contains calculations to select appropriate beams and columns for a compressor maintenance structure. It provides bending moment calculations for different sections of beams labeled A through F. It also calculates the moment of inertia, maximum bending moment, and tensile strength required for different C-channel beam profiles. Finally, it includes calculations to determine the compressive load capacity of a column with given dimensions.
