摘要
This Paper presents a brief account of the results from a series of tests on partially encased composite steel/concrete beam-columns under cyclic and pseudo-dynamic loading. The specimens were designed at Imperial College, in conformance with European code regulations. However, two unconventional features were incorporated. The first is the provision of additional transverse bars intended to inhibit local buckling at large displacements, and to increase the interaction between the two materials. The second is a reduced pitch for confining stirrups in the potential plastic hinge zone. The models were manufactured and tested at the Institute of Industrial Science, University of Tokyo. In comparison with the conventional European members, the modified section shows significant improvement in the ductility and energy absorption capacity under cyclic and transient dynamic loading.
