rectangular water tank design example using working stress method of design
Design of rectangular tank 1 Tank dimension height 2850mm and width 2850mm. SS 304 plate of thickness 4mm is provided by the client with 2 no of 75x6mm horizontal and vertical stiffeners equispaced as shown below Fig-1
Case-1 The required thickness of the plate tr was found to be 6.48mm but the plate deflection obtained was 10mm which is much greater than tr/2(please refer case-2 for detailed calculation). Minimum 10mm plate was required to hold the deflection within limits. Much reduced thickness can be obtained with the addition of more stiffeners. Case-2 Addition of 3 Nos of horizontal and vertical stiffeners equispaced Design data Table-A 1
