초록

In this study, as a part of the seismic retrofitting for school buildings, proposed of a new type of rotary friction damper, reviewed the performance and developed a experiment formula for the practical application. The rotary friction damper was composed of 4 shear plane using 2 friction pad. Considering a variety of yield moment, it was designed that clamping forces can be applied. The number of bolts were 9, 13 and thε clamping forces were 8 levels that the maximum load is the standard clamping forces. ±20mm displacement of the cyclic loading test were performed. As a result, the records of friction damper were stable. But sliding was ensured if the stress is 10-15% of the relation formula of sliding load in KBC 2009 by the bolts joining. However, when it is designed of that were inserted additional members for implementation of friction, the design of the level of 10% of the formula in KBC 2009 will be possible. And the design equation that is converted into the moment-rotation is proposed for the detailed design.
