V.AISC 360-16 Rect HSS E.9
Verify the available compressive strength of a rectangular HSS member per the AISC 360-16 code.
Details
From reference 2:
Select an ASTM A500 Grade C rectangular HSS compression member, with a length of 20 ft, to support a dead load of 85 kips and live load of 255 kips in axial compression. The base is fixed and the top is pinned.
ASTM A500 Grade C: Fy = 50 ksi

Section classification reported is for the cross section and loadcase that produced the worst case design ratio for flexure/compression Capacity results. 2. Results for any Capacity/Check that is not relevant for a section/loadcase based on the code clause in AISC 360-16 will not be shown in the report. 3. Bending results are reported as being �about� the relevant axis (X/Y), while the results for shear are reported as being for shear forces �along� the axis. E.g : Mx indicates bending about the X axis, while Vx indicates shear along the X axis. *** ABBREVIATIONS ***: ====================== F-T-B = Flexural-Torsional Buckling L-T-B = Lateral-Torsional Buckling F-L-B = Flange Local Buckling W-L-B = Web Local Buckling L-L-B = Leg Local Buckling C-F-Y = Compression Flange Yielding T-F-Y = Tension Flange Yielding STAAD SPACE -- PAGE NO. 4 STAAD.PRO CODE CHECKING - AISC 360-16 LRFD (V1.2) ***************************************************** ALL UNITS ARE - KIP INCH (UNLESS OTHERWISE Noted). - Member : 1 |-----------------------------------------------------------------------------| | Member No: 1 Profile: ST HSST12X10X0.375 (AISC SECTIONS)| | Status: PASS Ratio: 0.918 Loadcase: 3 | | Location: 0.00 Ref: Cl.E3 | | Pz: 510.0 C Vy: 0.000 Vx: 0.000 | | Tz: 0.000 My: 0.000 Mx: 0.000 | |-----------------------------------------------------------------------------| | COMPRESSION SLENDERNESS | | Actual Slenderness Ratio : 47.959 | | Allowable Slenderness Ratio : 200.000 LOC : 0.00 | |-----------------------------------------------------------------------------| | STRENGTH CHECKS | | Critical L/C : 3 Ratio : 0.918(PASS) | | Loc : 0.00 Condition : Cl.E3 | |-----------------------------------------------------------------------------| | SECTION PROPERTIES (LOC: 0.00, PROPERTIES UNIT: IN ) | | Ag : 1.460E+01 Axx : 6.249E+00 Ayy : 7.645E+00 | | Ixx : 3.100E+02 Iyy : 2.340E+02 J : 4.210E+02 | | Sxx+: 5.167E+01 Sxx-: 5.167E+01 Zxx : 6.110E+01 | | Syy+: 4.680E+01 Syy-: 4.680E+01 Zyy : 5.400E+01 | | Cw : 0.000E+00 x0 : 0.000E+00 y0 : 0.000E+00 | |-----------------------------------------------------------------------------| | MATERIAL PROPERTIES | | Fyld: 50.000 Fu: 62.000 | |-----------------------------------------------------------------------------| | Actual Member Length: 240.000 | | Design Parameters (Rolled) | | Kx: 0.80 Ky: 0.80 NSF: 1.00 SLF: 1.00 CSP: 12.00 | |-----------------------------------------------------------------------------| | COMPRESSION CLASSIFICATION (L/C: 3 LOC: 240.00) | | λ λp λr CASE | | Flange: NonSlender 25.65 N/A 33.72 Table.B4.1a.Case6 | | Web : NonSlender 31.38 N/A 33.72 Table.B4.1a.Case6 | | | | FLEXURE CLASSIFICATION (L/C: 3 LOC: 240.00) | | λ λp λr CASE | | Flange: Compact 25.65 26.97 33.72 Table.B4.1b.Case17 | | Web : Compact 31.38 58.28 137.27 Table.B4.1b.Case19 | |-----------------------------------------------------------------------------| STAAD SPACE -- PAGE NO. 5 STAAD.PRO CODE CHECKING - AISC 360-16 LRFD (V1.2) ***************************************************** ALL UNITS ARE - KIP INCH (UNLESS OTHERWISE Noted). - Member : 1 Contd. |-----------------------------------------------------------------------------| | CHECKS FOR AXIAL TENSION | |-----------------------------------------------------------------------------| | TENSILE YIELDING | | DEMAND CAPACITY RATIO REFERENCE L/C LOC | | 0.000 657.0 0.000 Cl.D2 3 0.00 | | | | Intermediate Results : | | Nom.
