ONESTEEL duragal sections

PART 1 SECTION PROPERTIES
D1.1 INTRODUCTION
The section property tables include all relevant section dimensions and properties necessary for assessing
‘DuraGal’ tubular steel structures in accordance with AS 4100 - 1998.
D1.2 SECTION PROPERTY TABLES
For each group of structural hollow section the tables include:
• Dimensions and Properties
• Properties for Assessing Section Capacity to AS 4100.
D1.2.1
Dimensions and Properties
The tables give standard dimensions and properties for DuraGal structural steel hollow sections. The
second moments of area are required for serviceability calculations and the radii of gyration are required
for assessing member stability. The elastic and plastic section moduli for bending about the various axes
are also tabulated. These are utilised in an intermediate step to determine the effective section modulus
for flexural design to AS 4100. The elastic section moduli are also used in the determination of elastic
stresses where design for fatigue must be considered, or where the stress state at serviceability loads
may need to be checked. The torsion constants are used in determining the torsional moment and angle
of twist per unit length.
