# V.AISC 360-16 WT Shape F.10

Verify the available flexural strength of a WT ("split tee") member per the AISC 60-16 code.

## Details

Verify the bending capacity of a WT5x6. The member is used as a 6.0 ft simple span. The member is continuously braced. The material is ASTM A992 (Fy = 50 ksi).

## Validation

The member is continuously braced, so lateral-torsional buckling does not control.

Yielding

 Mn = FyZx ≤ 1.6My [Eqn. F9-2]

where
 My = FySx = 50×1.22 = 61 in·k

Mn = 50×2.20 = 110 in·k > 1.6(61.0) = 97.6 in·k

Flange Local Buckling

λ = b/2tf = 9.43 (from Table 1-8 of Reference 1)

$λp=0.38EFy=0.3829,00050=9.15$
$λp=1.0EFy=1.029,00050=24.1$

λp < λ < λr, therefore, the flange is non-compact.

For non-compact sections:

 $Mn=Mp−(Mp−0.7FySx)(λ−λpλr−λp)≤1.6My$ [Eqn. F9-14]

Mn = 97.6 in·k = 8.13 ft·k

LRFD

ϕbMn = 7.32 ft·k

ASD

Mnb = 4.87 ft·k

## Results

Table 1. Comparison of results
ϕbMn (ft·k) 7.32 7.21 1.5%
Mnb (ft·k) 4.87 4.797 1.5%

***NOTE : AISC 360-16 Design Statement for STAAD.Pro.
*** AXIS CONVENTION ***:
========================
The capacity results and intermediate results in the report follow the notations
and axes labels as defined in the AISC 360-16 code.
The analysis results are reported in STAAD.Pro axis convention and the AISC 360:16
design results are reported in AISC 360-16 code axis convention.
------------    -----------     -------------
X               Z          Axis typically parallel to the sections principal major axis.
Y               Y          Axis typically parallel to the sections principal minor axis.
Z               X          Longitudinal axis perpendicular to the cross section.
SECTION FORCES AXIS MAPPING: -
------------    -----------     -------------
Pz              FX         Axial force.
Vy              FY         Shear force along minor axis.
Vx              FZ         Shear force along major axis.
Tz              MX         Torsional moment.
My              MY         Bending moment about minor axis.
Mx              MZ         Bending moment about major axis.
*** DESIGN MESSAGES ***:
=======================
1. 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.

***NOTE : AISC 360-16 Design Statement for STAAD.Pro.
*** AXIS CONVENTION ***:
========================
The capacity results and intermediate results in the report follow the notations
and axes labels as defined in the AISC 360-16 code.
The analysis results are reported in STAAD.Pro axis convention and the AISC 360:16
design results are reported in AISC 360-16 code axis convention.
------------    -----------     -------------
X               Z          Axis typically parallel to the sections principal major axis.
Y               Y          Axis typically parallel to the sections principal minor axis.
Z               X          Longitudinal axis perpendicular to the cross section.
SECTION FORCES AXIS MAPPING: -
------------    -----------     -------------
Pz              FX         Axial force.
Vy              FY         Shear force along minor axis.
Vx              FZ         Shear force along major axis.
Tz              MX         Torsional moment.
My              MY         Bending moment about minor axis.
Mx              MZ         Bending moment about major axis.
*** DESIGN MESSAGES ***:
=======================
1. 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
