Abstract:
This paper consists of three kinds of studies . One is static tests on three story shear wall assemblies to investigate the seismic behavior, particularly deformation performance and deformation mechanism, of flexural type shear walls. Second is static tests on flexural type beam-column asseniblies designed by either U.S. design practice or Japanese design practice . Third is correlation study on shaking table tests and pseudo dynamic tests developed for full scale seven story R/C building test. Major conclusions derived from these studies are a s follows; ( i ) Stretch of the boundary column under tension of the first story controlled the over all behavior of flexural type shear walls, ( i i ) The effect of slab reinforcements on bending capacity of beams was greatly remarkable, which caused pinching phenomena in a load vs. driftrelation while top of the beam was under tension, and (iii) Satisfactory correlation between shaking table tests and pseudo dynamic tests was obtained after the restoring force characteristics with the effects of strain rate and stress relaxation was appropriately evaluated.

A summary of the construction and instrumentation of the full scale seven story reinforced concrete test structure is presented. The general construction procedure and differences between Japanese and U.S. construction practices are discussed. Cross section dimensions, reinforcement details and material properties for all structural members are presented. Instrumentation consisted of 200 displacement transducers, 415 strain gages mounted on reinforcing bars and 120 strain gages mounted on the concrete surface. The types and locations of the instruments attached to the test structures are defined and discussed.

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.

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.

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.
