Abstract:
Studies conducted at the University of California at Berkeley on a 1/5th-scale model of a seven-story reinforced concrete frame-walll test structure are summarized in this paper and the results of these studies are evaluated. The degree of correlation between the experimental responses of this reduced-scale model and those of the full-scale model tested in Japan is assessed as is the degree of correlation between analytically predicted and experimental responses. The implications of these results for the states of the art and practice of the seismic resistant design and construction of framewall structural systems are discussed and improvements in the states of the art and practice are recommended.

Three one-tenth scale models of the large-scale reinforced concrete structure tested in Tsukuba, Japan, were built and tested at the University of Illinois, Urbane. The small-scale models were subjected to scaled earthquake motions in one horizontal direction. The paper describes some of the dynamic response measurements and discusses the observed strength of the structures in relation to planar limit analysis.

This paper presents the results of tests conducted on small-scale reinforced concrete models. Beam-column assemblies, an isolated shear wall, and a shear wall--frame unit were constructed to simulate portions of the full-scale test building at a scale of 1:12.5. Test results are used to determine the separate contributions of the wall, in-plane frame action, and transverse frame action in resisting lateral loads. Conclusions are drawn on the feasibility and limitations of small-scale model testing of reinforced concrete structures which are subjected to severe cyclic loading histories.

Four full-scale beam column slab assemblies were tested under reversed cyclic loads. The test program included two interior and two exterior joint specimens. The first two specimens, one interior and one exterior, were identical to beam column joints in the second story of the full-scale seven story structure tested in Japan. I n the remaining two specimens the longitudinal reinforcement in the beams and the columns was increased to provide a variation in beam-to-slab strength. Results are presented to give an overview of the experimental program. The behavior of the four specimens under reversed cyclic loads was excellent up to story drift levels estimated to correspond to the maximum deflection level imposed on the seven story structure. The influence of the slab on the strength of the floor system under imposed deformations was significantly greater than would be anticipated using the ACI effective slab width as a flange for T-beam analysis.

A planar wall-frame assembly and an isolated wall were constructed and tested under reversing static loads. The wall-frame assembly was a mediumscale representation of the wall-frame section of the full-scale structure tested in Japan. The isolated wall was identical to the wall section of the wallframe assembly. The analytically predicted strengths were ten and four percent less than the measured strengths of the wall-frame assembly and isolated wall, respectively. The overall behavior of the medium-scale specimens and the full-scale structure were similar. An analysis was made to predict the strength of the full-scale structure by scaling up the medium-scale results. However, it was only after calculations were made including strength contributions of three- dimensional effects, that the analysis agreed well with measured strength of the full-scale structure. Measured strains indicated that boundary element hoops were subjected to significant strain only over the lower portions of the first story. Strains in all other boundary element hoops monitored were relatively small. None of the instrumented column hoops or beam stirrups experienced strain greater than yield, even though several instrumented stirrups were located in beam hinging regions.
