® WorleyParsons <br /> resources&energy <br /> — Test loads of equipment and piping (excess over dead load). <br /> — Thermal force caused by thermal expansion of equipment and piping under all <br /> operating conditions. <br /> 2.3.8.3 Dynamic loads <br /> These loads will be considered and applied in accordance with the manufacturer's <br /> specifications, criteria, or recommendations, and industry standards. Rotating parts will <br /> be considered as a vibrating mass. <br /> 2.3.8.4 Vehicle loads <br /> Underground piping, conduits, trenches, sumps, and foundations accessible to truck traffic <br /> will be designed for HS-20-44 truck wheel loads per the AASHTO Standard Specification <br /> for Highway Bridges. <br /> 2.3.8.5 Seismic loads <br /> All equipment will be designed to withstand the seismic loading requirement specified in <br /> the governing building code for the seismic zone rating of the project site. <br /> In addition, equipment anchorages and supports will be designed to prevent overturning, <br /> displacement and dislocation in accordance with governing building code requirements. <br /> Piping, cable tray and ductwork will be investigated to determine if stops or other <br /> restraints are required. <br /> 2.3.8.6 Wind Loads <br /> Wind pressures and shape factors will be applied to all system components and exposed <br /> equipment in accordance with governing building code. <br /> Allowances will not be made for the effect of shielding by other structures. <br /> The overturning moment calculated from wind pressure will not exceed two thirds of the <br /> dead load resisting moment. The uplifting forces calculated from the wind pressure will <br /> not exceed two-thirds of the resisting dead loads and adequate structure-foundation ties <br /> will be designed to resist wind forces. <br /> 2.3.8.7 Other Loads <br /> Other expected loads (water hammer, dynamic loads from operating equipment, system <br /> modulation, etc.) required to predict the response of structures will be considered where <br /> appropriate. <br /> Proper load combinations will be used for structural steel and reinforced concrete to <br /> comply with applicable codes and standards and with vendor requirements. <br /> Lodi Energy Center 3.2-7 LEC AFC <br /> 071608 Rev.A <br />
