概要 RC coupling beams with low-yield-point steel web panel in the mid-span (coupling beam damper) have been developed and applied to
actual buildings. Cyclic loading tests had been performed, resulting that the coupling beam dampers provided the stable hysteretic
performance and load carrying capacity did not deteriorate up to 1/20 of drift angle.
In this paper, finite element analysis has been carried out to evaluate the shear buckling strength of the coupling beam damper. It is
verified that the low-yield-point steel web panel (with width-thick ratio of about 15) of the coupling beam damper is thick enough to
avoid shear buckling. Restoring force characteristics of the coupling beam dampers for structural design is also proposed. An
appropriate modeling of RC parts is important to represent the total structural performance.
