Dynamic tests on the ductility of composite steel-concrete beams.

摘要

Three tests performed with a shaking table on simply composite steel-concrete supportedbeams are considered in this paper. The purpose of the test program was to determine theconditions to realize ductile composite steel-concrete sections when these are submitted to seismicaction. And, mainly, to evaluate an important parameter: the concrete crushing strain ecu. This parameteris required for the plastic design of composite steel-concrete structure and is still unknownin the case of seismic solicitations.
