Problem

A C15x33.9 section is subjected to an axial dead load of 4 kips and live load of 10 kips. Assume a shear lag factor of U = 0.8 and a net area of 90% of the gross area due to the connections. The material is Grade 70 steel.

Section Properties

From reference #2

  • Gross area, A = 10.0 in2

Calculations

Section Forces

This example will use a single load case for both LRFD and ASD examples: 1.0DL + 1.0LL.

Pu = Pa = 4 + 10 = 14 kips

Tension Rupture

An = 0.90 × A = 0.9 (10.0) = 9.0 in2
Ae = AnU = 9.0 × 0.8 = 7.2 in2

 *** AXIS CONVENTION ***:
 ========================
 The capacity results and intermediate results in the report follow the notations
 and axes labels as defined in the AISC 360-22 code.
 The analysis results are reported in STAAD.Pro axis convention and the AISC 360:22
 design results are reported in AISC 360-22 code axis convention.

 *** 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 360-22 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 360-22 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 360-22 code.
 The analysis results are reported in STAAD.Pro axis convention and the AISC 360:22
 design results are reported in AISC 360-22 code axis convention.
   AISC Spec.      STAAD.Pro      Description
  ------------    -----------     -------------
       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: -
   AISC Spec.      STAAD.Pro      Description
  ------------    -----------     -------------
       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 360-22 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 ***:
 ======================

    L-T-B = Lateral-Torsional Buckling
    F-L-B = Flange Local Buckling
    W-L-B = Web Local Buckling
