Abstract
The damages of many reinforced concrete buildings at 1968 Tokachioki Earthquake suggested that the rigidities, the strength and the failing behaviour were greatly influenced by the spandrel or wing walls in the frames. However, the influences of these walls on the structural characteristics have never considered into the structural frame analysis and the proportioning of the members, since the data on these problems were few and the design methods for the frames with these walls were not established. In this paper, it was attempted to consider the influences of the spandrel or wing walls in the structural frame analysis and the proportioning of the members, and the results of analysis were compared with the results of statically loaded tests. The results for the ultimate bending strength and for the shear strength at creaking were compared in Table 3. The initial regidities were compared with the results obtained from the various methods of analysis in Table 4. The hysteretic characteristics at the cyclic loading in plasticity were discussed in Fig. 12-Fig. 15.
