DesignCalcs now supports a general stress check on the pressure envelope for vertical vessels supported by Support Lugs and Support Rings. Previously, only the structural steel was checked. This includes consideration for internal pressure/vacuum, weight, horizontal wind, horizontal and vertical seismic cases. DC-6488
The hydrostatic test condition now includes the option to limit Pm to 0.9Sy. When this is checked, primary tensile stress checks in the Zick Analysis, Tower Analysis, Leg, Lug and Support Ring calculations for the pressure envelope will be compared against max(S , 0.9Sy)E instead of SE. “E” represents the girth seam efficiency and “S” represents the allowable stress at ambient. The “Sy” represents the yield at ambient temperature. Ambient is assumed to be 70 °F (20 °C). This new option is displayed in the Vessel window in the Wind and Seismic tabs. The software defaults the value to an unchecked status. DC-10055
DesignCalcs now supports the ability to export lifting lug designs in NozzlePRO. Type 1 and Type 2 lifting lugs can be exported for hosts that are cylindrical shells, hemispherical heads, ellipsoidal heads, ASME F&D and Torispherical Headstorispherical heads. This supports the option with or without repads. DC-9827.
