Explanation Given information: A wide-flange W8 × 15 of A36 steel acts as a column. The length of the column is L = 10 ft . The eccentric load applied on the column, P . Show the AISC equation of Sec 13.6 as follows: σ allow = [ 1 − 1 2 ( K L r ( K L r ) c ) 2 ] σ Y [ 5 3 + 3 8 ( K L r ( K L r ) c ) − 1 8 ( K L r ( K L r ) c ) 3 ] Here, σ allow is the allowable stress, σ Y is the yield stress, E is the Young’s modulus, and ( K L r ) is the slenderness ratio. Show the expression for Equation 13-30 as follows: σ max = P A + M c I Here, σ max is the maximum compressive stress, P is the load, A is the area, M is the moment, c is the distance between the centroid of member and outer fibre, and I is the moment of inertia. Calculation: Refer the Appendix B. Show the geometric properties of W8 × 15 section as follows: The area ( A ) of the W8 × 15 section is 4.44 in . 2 The least radius of gyration ( r x ) of the W8 × 15 section is 3.29 in . The least radius of gyration ( r y ) of the W8 × 15 section is 0.876 in . The moment of inertia, ( I x ) = 48 in . 4 . The depth of the section, d = 8.11 in . Show the expression for ( K L r ) c as follows: ( K L r ) c = 2 π 2 E σ Y (1) Here, K is the effective length factor, L is the length of the column, and ( r ) is the radius of gyration, E is the Young’s modulus, and σ Y is the yield stress of the material. Consider the Young’s modulus of the steel is E = 29 × 10 3 ksi . Consider the yield stress of the steel is σ Y = 36 ksi . Substitute 29 × 10 3 ksi for E and 36 ksi for σ Y in Equation (1). ( K L r ) c = 2 π 2 × 29 × 10 3 36 = 58 , 000 π 2 36 = 126 Calculate the slenderness ratio about y-y axis. Calculate the value of ( K L r y ) as follows: The value of effective length factor, K = 0.5 , since both ends are fixed. Substitute 0.5 for K, 10 ft for L, and 0.876 in . for r y . ( K L r y ) = ( 0.5 × 10 ft × 12 in . 1 ft 0.876 in . ) = 68.5 Show the condition for the column to be a long column as follows: ( K L r ) c ≤ ( K L r y ) ≤ 200 (2) Substitute 68
