WebDesign a timber column which is 3 metres long, supported as shown in the figure and loaded with a compressive load of 15kN. Allowable compressive stress (d cw) for the timber is 5.2N/mm². Table 4.5 Reduction Factor, (k), for Stresses with Respect to the Slenderness Ratio for Wood Columns Webcolumn A, we can find the critical stress , as Pcr cr F ()()2 2 2 2 KL / r E KL A EI A P F cr cr π π = = = where r is the radius of gyration of the cross section about the axis of bending (I =Ar2) and KL/r is called the slenderness ratio of the column. A thin column has small radius of gyration and a stocky column has large radius of gyration.
WebIn general, a steel column having a critical effective slenderness ratio of greater than 120 or an aluminum column having one of greater than 220 may be immediately treated as a long column. Columns having lower effective slenderness ratios must be checked by Equation (2-12) or Table 2-3 or treated by a method applicable to both long and short ... WebSep 23, 2024 · The ratio of the effective length of a column to the least radius of gyration of its cross section is called the slenderness ratio. Short RCC column, =< 10; Long RCC column, > 10; Short Steel column, =<50; Intermediate Steel column >50 & <200; Long Steel column >200; 3. Based on type of loading.
