Abstract:
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.

Earthquake response tests on a full scale seven story R/C building structure were carried out by employing an equivalent single-degree-of-freedom pseudo-dynamic test method. First, the structure without nonstructural elements was tested from small magnitudes of response (elastic range) to large response (heavy damaged range). Second, the damaged structure was repaired and strengthened, and nonstructural elements were installed . After this, the structure was tested by the same test procedure as that used for the original tests . This paper presents the responses, the restoring force characteristics, and the observed damage obtained during the tests before and after the repair work. This paper also presents the dynamic characteristics obtained through vibration tests.

This paper is intended to discuss the inelastic behavior of the seven-story full-scale reinforced concrete building observed i n the pseudo-dynamic test. Analyses of the data led to the observations regarding structural response, as affected by the behavior of the constituent members of the building such as slabs, beams, columns and wall . Most significant findings from the studies are: (1) slab reinforcement contributes to the flexural resistance of the beams to a much larger extent than suggested in many building codes, (2) the transverse beams connected to the tensile boundary columns of the wall restrain the upward movement of these columns increasing the axial compression in these members, and (3) the maximum lateral strength of the building should be evaluated by incorporating these observations.

This paper describes an analysis of the full-scale seven-story reinforced concrete building tested as part of the U.S.- Japan Cooperative Research Program Utilizing Large Scale Testing Facilities. A general purpose computer program was developed to simulate the inelastic behaviour of a reinforced concrete shear wall-frame structure. On the basis of given structural geometry and material properties, this paper places an emphasis to clarify (a) methods to model member hysteresis behaviour and (b) methods to determine member stiffness properties. A good correlation of the observed and computed response of the test structure is reported including waveforms, hysteresis relations, and local deformations.

Analyses are made to indicate how member strengths and reinforcement details used in the full scale reinforced concrete test structure compared to appropriate design requirements of the 1979 Edition of the Uniform Building Code (1) and current Japanese Building Standard Law (2, 3) and Architectural Institute of Japan Standard (4) . Comparison between the test structure and the design requirements of the Uniform Building Code indicate that even though the test structure was intended to represent a dual bracing type of structure, certain minimum strength and reinforcement detailing requirements of the Code were not satisfied . However, the provided member strengths and reinforcement details were considered to be sufficient to provide the needed dissipation of energy (through stable hysteresis behavior) to survive major seismic excitations without excessive damage. This was considered possible due to the relatively low percentages of longitudinal steel that we reused in the test structure and thus, only low or moderate shear stresses should be developed due to flexural hinging. The structural members were smaller and the reinforcement ratios were less than those normally found in a Japanese building of this size . Member capacities were considerably below that required in Japan and the ultimate lateral load capacity was approximately 65 percent of the required value.
