The structural steel column is fixed at its base and free at its upper end. Assume L= 13.0 ft, a = 0.99 in., b = 7.5 in., c= 9.48 in., d = 9.48 in., and t = 0.79 in. At the top of the column, a load P is applied to the stiffened seat support at an eccentricity of e from the centroidal axis of the wide-flange shape. Using the allowable stress method, determine the maximum allowable eccentricity e if (a) P = 18 kips and (b) P = 32 kips. Apply the AISC equations given in Section 16.5 and assume that E = 29,000 ksi and oy = 50 ksi. eccentricity e y d Cross section y

Question
Transcribed Image Text:The structural steel column is fixed at its base and free at its upper end. Assume L = 13.0 ft, a = 0.99 in., b = 7.5 in., c = 9.48 in., d =
9.48 in., and t = 0.79 in. At the top of the column, a load P is applied to the stiffened seat support at an eccentricity of e from the
centroidal axis of the wide-flange shape. Using the allowable stress method, determine the maximum allowable eccentricity e if (a) P
- 18 kips and (b) P = 32 kips. Apply the AISC equations given in Section 16.5 and assume that E = 29,000 ksi and oy = 50 ksi.
