: Expansion and contraction caused by fluctuating flue gas temperatures. 3. Fabrication and Erection

Tolerances for out-of-roundness and misalignment of shell courses. Safe lifting, transport, and field erection procedures. 4. Inspection and Maintenance

Prior to 2016, the standard's wind loads were based on ASCE 7-05, which used for Allowable Stress Design (ASD). Later versions of the ASCE 7 standard switched to using Ultimate Wind Speeds . To bridge this gap, STS-1-2016 introduced a conversion equation to transform Ultimate Wind speeds into equivalent Service Level speeds.
