Zusammenfassung: | The beam element for three-dimensional pure steel frames proposed by the first author is extended for steel-concrete composite members. The authors call this approach the 'fibered plastic hinge method'. The stress-strain relation of a concrete fiber is modeled as an elastic-perfectly plastic type in this study. Comparisons with the, authors' experimental results on RC beams strengthened by carbon fiber sheet and available test results on steel-concrete composite columns and frames show that the developed beam element has a sufficient accuracy for bending problem although there are some limitations. The element may be used to examine a performance of moment-resistant steel-concrete composite frames. |
