Watchtower Analysis: Structural Optimization for a Steel Observation Tower

Key Challenges

• Optimization of member sizes

The primary challenge was optimizing steel member sizes to reduce overall material consumption without compromising structural integrity or safety, particularly under high wind and snow loads.

• Structural connection complications

BIM coordination presented additional complexities, especially around the intricate node configurations where multiple structural elements converged.

• Precise load calculations

Ensuring accurate load calculations for multiple conditions, including dead, live, wind, and snow, was critical for regulatory compliance under AISC 360-16 standards.

• Requirement of accurate clash detection

Clash detection was essential to avoid design conflicts between structural members and ensure smooth prefabrication and on-site assembly.

Approaches and Solutions

• The Gsource engineering team performed a comprehensive load analysis using industry-standard simulation tools, validating the structure against dead, live, seismic, wind, and snow loads.

• Through iterative modeling, steel members were optimized for size and material use, achieving cost efficiencies without compromising safety.

• Clash detection was conducted in Revit and Navisworks, allowing resolution of geometric conflicts in complex joint areas before fabrication.

• Final deliverables included detailed shop and erection drawings, alongside deflection and load analysis reports to support the permitting process.
