3. IT6.2, P3] Please check the AISC Manual to determine the self-weight, moment of inertia (L.) and cross-sectional areas for the following hot-rolled standard sections. W14x22; W21x44; HSS 6x6x0.5; L6x4x1/2; C12x30; WT 18x128

Solution

i) W14x22:: self-weight : 22 lb/ft

Moment of inertia (Ix) : 199 in⁴

Cross-sectional area : 6.49 in²

ii) W21x44:: self-weight : 44 lb/ft

Moment of inertia (Ix) : 843 in⁴

Cross-sectional area : 13 in²

iii) HSS 6x6x0.5:: self-weight : 35.1 lb/ft

Moment of inertia (Ix) : 48.3 in⁴

Cross-sectional area : 9.74 in²

iv) L6x41/2:: self-weight : 16.2 lb/ft

Moment of inertia (Ix) : 17.3 in⁴

Cross-sectional area : 4.75 in²

v) C12x30:: self-weight : 30 lb/ft

Moment of inertia (Ix) : 162 in⁴

Cross-sectional area : 8.81 in²

vi) WT 18x128: self-weight : 128 lb/ft

Moment of inertia (Ix) : 1210 in⁴

Cross-sectional area : 37.7 in²
