Abstract
For the effect of opening upon the rigidity of multistoried quake-resisting wall, some tests have been made on models. But definite data directly available for structural calculation have not yot been got after these tests. It seems to me that the reason is that a special consideration has not been paid to the method of choosing a model and to the method of loading. In this thesis, the test on the effect of opening upon bending rigidity and frame rigidity is made, using a new and special model and method of loading; the limit point of the so-called large opening and small opening are indicated; a test formula available for structural calculation is devised; and frame rigidity, shown in the method of frame substitution for large opening that the Muto Laboratory of Tokyo University suggested, is examined.
