Explanation Given: H S S 9 × 7 × 3 8 F y = 46 k s i f c ' = 4 k s i Formula used: P n o = F y A s + F y s r A s r + f ' c A c Where, F y is yield stress of the steel shape. A s is cross-sectional area of the steel shape. F y s r is yield stress of the longitudinal reinforcing steel bars. A s r is cross-sectional area of the reinforcing steel. P e = π 2 ( E I ) e f f ( K L ) 2 Where, P e is the Euler buckling load. ( E I ) e f f is the effective flexural rigidity of the composite section. ( E I ) e f f = E s I s + 0.5 E s I s r + C 1 E c I c I s is moment of inertia of the steel shape about the axis of buckling. I s r is moment of inertia of the longitudinal reinforcing bars about the axis ofbuckling. I c is moment of inertia of the concrete section about the elastic neutral axis of the compositesection. Calculation: The following dimensions and properties from Part 1 of the Manual will be needed: For an H S S 9 × 7 × 3 8 , A s = 10.4 i n . 2 t ( d e s ) = 0.349 i n . I y = 80.4 i n . 4 A s is cross-sectional area of member. t(des) is design wall thickness. I y is moment of inertia of member taken about Y-axis. E c = w 1.5 f c ' = ( 145 ) 1.5 4 = 3492 k s i The area of concrete Ac can be estimated as b d − A s b = 7 i n . d = 9 i n . b is width of member d is depth of member parallel to Y-axis b d − A s = 7 ( 9 ) − 10.4 = 52.6 i n . 2 or more accurately as follows: The corner radius is given in Part 1 of the Manual as 2 t(des). The area of a quarter-circle spandrel with a radius r is r 2 − π r 2 4 = ( 2 t ) 2 − π ( 2 t ) 2 4 = t 2 ( 4 − π ) = 0.349 2 ( 4 − π ) = 0.105 i n . 2 And since there are four of these segments to be deducted from the area b d − A s , A c = b d − A s − 4 ( 0.105 ) = 7 ( 9 ) − 10.4 − 4 ( 0.105 ) = 52.18 i n . 4 For computing the moment of inertia of the concrete, the moment of inertia of the spandrel about an axis parallel to the 9-inch side through the point of tangency is I = ( 1 3 − π 16 ) r 4 = ( 1 3 − π 16 ) ( 2 t ) 4 = ( 16 3 − π ) t 4 = ( 16 3 − π ) ( 0
