Abstract: Beam-column or beam-wall connections are
an important problem in high-rise buildings. In this study, based on the
analysis of an example structure, an analytical model for design of the
semi-rigid connections between steel beams and RC walls in high-rise hybrid
buildings is proposed. Also, the mechanical characteristics of these connections
subjected to low-reversed cyclic loading are investigated through comparison of
experimental results from three semi-rigid connections and two rigid
connections. Moreover, some latent problems for design of these connections as
well as the corresponding solutions are discussed. The results from the
experiments and analyses indicate that semi-rigid connections exhibit
satisfactory capacity and seismic performance, and the proposed design can be
used in practice.
