Calculate Required Tube Size Using Structural Properties Home / Resources / Calculators / Calculate Required Tube Size Using Structural Properties The calculator can be utilized by anyone that knows the loading criteria of their application and whether the tube will be used as a beam or column. CE 405: Design of Steel Structures – Prof. . Therefore deflection is maximum at the center of the plate i. kuzmin. 5 4 8. A point load of 900 N is placed at the middle. 06415 (29 10 )(103 ) k ft ft in ft) ks in /2 34 2 (10 ) (20 10 ) 24(29 10 )(103 )(20 ) k ft ft ft ft ksi n ft (4 11. Remember: 1 m = 1000 mm ; 1 N/mm = 1000 N/m ; 1 Nm = 1000 Nmm. The final formula we need to know for our analysis is the Area Moment of Inertia (Area MOI). > 5 w L4/(384 E I x) Therefore, Ix > 644. Hollow structural sections (HSS) are extremely stiff torsionally compared to open sections, but the distribution of the steel cross-section relative to its neutral axis is not as efficient as that of open sections. 5 6. When a structural member is subjected to a compressive axial force, it's referred as a compression member or a column. θ = 32 L T / (G π (D 4 - d 4 )) Where: D = outside diameter (mm, in. Take D0 = 40 mm, t = 2 mm, G = 80 GPa, L = 1 m, and T = 200 Nm. hollow tube deflection formula
