Code Requirements for the Evaluation and Design of Rooftop Equipment Supports

摘要

Placing ammonia piping and equipment on the roof of a building presents additional loading challenges that the pipe designer may not typically address. General loading concerns including; service loads, gravity loading, and where applicable-seismic loads, should be addressed for any above ground pipe system. However, wind loading on rooftops or exterior exposed piping can present a unique design challenge for the pipe systems and the support components. This paper will review current code requirements specifically associated with wind and seismic loading on rooftop applications. Even if addressing this loading is outside the scope of work, a knowledge of the requirements can aid in better system coordination and design.
