ASME STS-1-2021 completely rewrites the seismic section to harmonize with ASCE 7-16’s Risk-Targeted Maximum Considered Earthquake (MCER) ground motions. Owners in high-seismic zones (e.g., California, Alaska, Japan) must pay close attention to Chapter 8, which introduces new response modification coefficients for stacks lined with brick or castable refractory.
Comprehensive Guide to ASME STS-1-2021: Steel Stacks Standard Asme Sts-1 2021 Pdf
The standard classifies and regulates several types of stack configurations: ASME STS-1-2021 completely rewrites the seismic section to
Note : Use for flammable gases requires additional considerations (like internal deflagration pressure) not fully defined in this standard. Seismic analysis has become more rigorous
Seismic analysis has become more rigorous. The 2021 edition provides updated response spectra and detailing requirements for anchor bolts and base plates to ensure stacks can withstand lateral ground forces without buckling. 3. Refined Vortex Shedding and Damping Rules
