抄録

To know availability of simplified structures of column ancorages, we examined 3 type specimens by vertical and horizontal loadings, and measured their stress distributions and deformations. Main conclusions we got by the experimental research on simplified types are as follows. 1. Between 3 type specimens under vertical loads, no great distinctions of mechanical behaviors are noted. 2. Under horizontal forces, additional stresses and local deformations of details are remarkable. 3. Moment and shear stresses added to anchor bolts are significant. 4. Stresses in wing plates are negligible. 5. Rotational rigidities of column anchorages are reduced mainly by partial deformations of ribs.
