Buckling factor of safety formula
WebA water hammer analysis has shown that accidental event may result in a negative pressure of -9m. Check that in this case there is an adequate factor of safety against buckling. Using AS/NZS 2655.1 and the trench and soil conditions, an E’ value of 6.3MPa is derived. From the equation, P b = 590 kPa. WebThe Euler buckling load can then be calculated as. F = (4) π 2 (69 10 9 Pa) (241 10-8 m 4) / (5 m) 2 = 262594 N = 263 kN. Slenderness Ratio. The term "L/r" is known as the slenderness ratio. L is the length of the column and …
