The design of reinforced concrete structures for extreme events requires accurate
predictions of the ultimate rotational capacity of critical sections, which is dictated by
the failure mechanisms of shear, hoop fracture, low-cycle fatigue and longitudinal bar
buckling. The purpose of this research is to develop a model for the full compressive
behavior of longitudinal steel including the effects of bar buckling. A computational
algorithm is developed whereby experimental data can be rigorously modeled. An
analytical model is developed from rational mechanics for modeling the complete
compressive stress-strain behavior of steel including local buckling effects. The global
buckling phenomenon is then investigated in which trends are established using a
rigorous computational analysis, and a limit analysis is used to derive simplified design
and analysis equations. The derived buckling models are incorporated into wellestablished
sectional analysis routines to predict full member behavior, and the
application of these routines is demonstrated via an incremental dynamic analysis of a
ten-storey reinforced concrete building. The buckling models and the sectional analysis
routine compare favorably with experimental data. Design recommendations and topics
for further research are presented.
