The influence on steel tubular strut load capacity of strain hardening, strain aging and the Bauschinger effect
AbstractAn experimental study of tubular steel strut strength with a variety of material effects is described. Sixty pin-ended strut tests are carried out on tubes that have been subjected to tensile and compressive loading. The results are studied by statistical analysis. It is found that the Bauschinger effect and strain aging have significant influences on strut load capacity; the effect of strain hardening on load capacity is not as significant as strain aging. A comparison is also made between the observed strut load capacities and theoretical results predicted using the simple tangent modulus method. There is seen to be reasonable agreement between the strut test results and the calculated curves derived from the tangent modulus method.
