A tall fractionating column that is 14m long is made of a 30

A tall fractionating column that is 14m long is made of a 304.2mm ID standard steel pipe with weight of 74 kg/m and wall thickness of 9.5 mm. During operation, the column is internally pressurized to 4.1 mPa and has a wind load of 600 N/m as shown. What is the state of stress at point A, on the windward side of pipe? Show all calculations and place the stresses on an equilibrated element Determine if element is a planar state of stress and state reason

Solution

State of stress at A is given by the following

Tensile stess in horizontal direction 89 kpa

Compressive in vertical direction= 45 kpa

Shear stress= 23kpa
