Dead Load - The weight of materials forming the building, structure, foundation, and all permanently attached process vessels, piping, and other permanent equipment. Dead loads for various load combinations may include the following types:

Empty dead load is the empty weight of process equipment, vessels, tanks, piping, and cable trays.

Erection dead load is the fabricated weight of process equipment or vessels and is generally taken from the certified equipment or vessel drawing.

Operating dead load is the empty weight of process equipment, vessels, tanks, piping, and cable trays plus the maximum weight of contents (fluid load) during normal operation.

Structure dead load is the weight of materials forming the structure (not the empty weight of process equipment, vessels, tanks, piping, nor cable trays), foundation, soil above the foundation resisting uplift, and all permanently attached equipment (e.g., lighting, instrumentation, Heating, Ventilation and Air Conditioning (HVAC), sprinkler and deluge systems, fireproofing, and insulation, etc.).

Test dead load is the empty weight of process equipment, vessels, tanks, and/or piping plus the weight of the test medium contained in the system.
