In this paper, nonlinear behavior of beam and column members of the full-scale reinforced concrete structure was examined based on the data obtained from the pseudo-dynamic tests. Such examination has revealed the followings ; 1) Significant elongation of the wall boundary column forced the beams adjacent to this column to be deformed about 80 to 110% greater than the other beams, 2) Beam hinge rotation was estimated about 80 to 90% of the building rotational angle, as defined as roof floor level deformation divided by the structure hight, when the beam was subjected to positive bending, and was about 50 to 60% when subjected to negative bending, 3) Slab width effective to the beam negative moment resistance was observed to reach 85% of the entile slab width for longitudinal beams, and 4) Beam reinforcing bars were computed to dissipate more than 70% of the total energy of the beam hinge region.
