Question
The two bay structure shown below carries a rotating machine (demarcated by the dotted line). The Dead Load (DL) and Live Load (LL) from the machine are indicated on the drawing. Free access below Question 2 the machine and through the structure is required in the A-B-C direction. (a) Alter the general arrangement if necessary (b) Provide a walkway around the perimeter of the structure to service the machine. The walkway is to be 1.5m in width (c) Stabilize the structure. DL4LL4 DL,LL DL3 LL DL LL DL4LL Rotating Machine. Outline 5m 2 Plan ElevationsExplanation / Answer
a) The given frame is a sway frame because of hinge supports at 1 and 2. For any structure sway is always prevented So to become a non sway frame by providing fix supports at 1 and 2.
b) provide a walkway means what to provide a drawing or some other can't understand question . In technical terms provide a slab thickness more than require to bear liveloads and rolling loads since these loads are suddenly applied load it means stress and axial deformation are twice as type of gradually applied loads.
c) Provide fix supports at 1 and 2 or provide a diagonal member at least 1 to prevent from sway and the structure becomes stable.
