Abstract:
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.
