Industrial equipment can be elevated or ground supported depending on equipment operations, process requirements, or construction methods used in modularization. It is required to consider each stage of operation of the equipment – including installation, maintenance requirements, operating temperature changes, operating and accidental loads, and environmental loads – for the design of supporting structures. The support types and connections can be arranged differently due to different operating requirements for each piece of equipment. Structure behavior can be complicated for a group of mechanical systems that may be elevated, ground supported or on separate structures connected by large size pipes or ducts, particularly for those supported by tall structures. It is essential to coordinate among disciplines and vendor suppliers for a successful equipment supporting system design.
This paper discusses design considerations for equipment supporting structures. Considerations include interactions between equipment and supporting structures, structural framing system selection, analysis model types, structural rigidity, design loads, and framing connections. Case studies of analysis modeling, comparison of brace layout, connections between equipment and structural supports, load paths from equipment to supporting structures, structure natural frequencies, and structure to foundation connections is included and discussed.
