Abstract
Eight Type 3CR 12 beams of varyious lengths were subjected to equal end moments
untill failure. This loading arrangement ensure that the portion of beam between
supports only experience pure bending and no shear. The magnitude of the shear
force was limited, to ensure that shear failure was unlikely at the leverarms.
Coupons, sampled from the beams before testing, were subjected to tensile and
compression tests to establish the mechanical properties of the material of each
beam. Strain and deflections were measured at numerous places along each beam.
This enabled the derivation of the material properties and essential beam design
parameters
The beam-test results used along with relevant beam theory, enables the compilation
of design formulae to be included in a much needed first edition of a hot-rolled
stainless steel design specification. At numerous stages in this study the relevant
properties of Type 3CR 12 steel is compared to the corresponding properties of mild
steel in order to assess the relation between mild steel and stainless steel.
