Pcr=π2EI(KL)2) and yielding (Py=FyA ).
Combined Stresses: Use interaction equations (e.g., AISC) for members under axial load and bending moments.
Connections: Verify bolt/weld capacities for shear, tension, and bearing.

5. Design Codes and Safety Factors

Relevant Standards: TIA-222 (telecom structures), ASCE 7 (environmental loads), AISC (steel design).
Load Combinations: Apply code-specified combinations (e.g., 1.2D + 1.6W).
Safety Factors: Incorporate factors of safety (e.g., 1.67 for AISC LRFD) to ensure reliability.

6. Example Calculation Outline

Wind Load Example:
Fw=0.00256⋅Kz⋅Kzt⋅Kd⋅V2⋅Cd⋅A
Where V is wind speed (mph), Kz is exposure coefficient, Cd is drag coefficient, and A is projected area.
Member Check: For a 50x50x5 mm angle (A=480 mm2, r=9.8 mm), if KL/r=100, critical stress Fcr is calculated per AISC.

7. Software and Professional Input
