: The Beam Column Shown Below Is Pinned At Both Ends And Is Subjected To The Loads Shown Bending Is About The Strong Axis 2 (40.88 KiB) Viewed 42 times

The beam-column shown below is pinned at both ends and is subjected to the loads shown. Bending is about the strong axis only. Calculate the Interaction Value (answer in 3 decimal places i.e. 0.291, 1.043) using Allowable Stress Design. Use a Cb=2.22 Po=532 KN PL=618 KN MD Top=503 kN-m MLTop=237 kN-m MDBot=117 kN-m MLBot=162 kN-m L-4.57m Steel section is a A992 W12x72 Properties of W12x72 Fy=345 MPa A=13,613 mm Sy=541x10 mm Ly=81x10 mm Zy=806x103 mm 5x=1596x103 mm3 Ix=248X106 mm Zx-1770x100 mm ry=77.22 mm
Ix=248x100 mm Zx=1770x10 mm ry=77.22 mm x=134.87 mm Lp=3.26m Ir=11.43m Consider Pdelta in calculating the interaction value by using the factor Cm Bi - 1-2 PD PL Мртор MLTop L Мрвот MLB
