reodata 4.0 - OneSteel Reinforcing

The design tensile capacities of fine-threaded 500PLUS ® REBAR can be
determined in accordance with AS 4100 * . Based on the results of testing,
fine-threaded 500PLUS ® REBAR has a reduced characteristic yield stress
equal to 75% of the normal characteristic yield stress (500 MPa) and
a reduced characteristic tensile strength equal to 85% of the normal
characteristic tensile strength (540 MPa) based on the thread stress area.
It follows that OneSteel Reinforcing 500PLUS ® REBAR when cut with
AS 1275 ** metric threads and fitted with AS 1112 *** Property Class 5 nuts,
has the values of design tensile capacity specified in the adjoining table.
These design tensile capacities are based on the effective tensile stress
areas (As) from AS 1275 ** , a strength reduction factor f = 0.8, and
a characteristic tensile strength equal to 0.85 x 540 = 459 MPa.
^ Denotes second choice thread size. Nuts may be difficult to obtain. N.B. Engineers
should be aware that threading reinforcing bars this way also reduces the ductility
to less than the minimum requirements for Class N bars specified in AS/NZS 4671.
Design Tensile Capacity = f As x 0.85 x TS where TS = 540 MPa
* AS 4100 : 1998 Steel structures,
** AS 1275 : 1985 Metric screw threads for fasteners
*** AS 1112 : 2000 ISO metric hexagon nuts
