Abstract:
Strain rate-dependent models of steel and concrete were used in fiber modeling of reinforced concrete sections. This model was used for studying the strain rate effect on the axial-flexural strengths of typical reinforced concrete sections. Results are presented in the form of interaction diagrams for different strain rates ranging from the slow rates expected during the quasi-static laboratory tests to the high rates observed during the response of structures to seismic and blast loadings. Influence of the position and percentage of the longitudinal steel; the material properties; and the size, shape, and confinement of the section on the strain rate effects are discussed. Comparisons are made with available experimental results.
