A study on seismic retrofitting method with siding board for existing timber buildings

It aims to mention about the various examinations to use an exterior siding material as a retrofitting method of construction of the existent buildings. The retrofitting methods of construction of three cases are proposed. In the Case I method, the siding is changed of the existent wall of the range (about 2.0 m) that a part reaches ground floor. In this case, a foothold cost can be reduced. In the Case 2 method, a thickness siding is raised even on the beam. In this case, it works for the improvement in the seismic performance and the fireproof performance. Because a proof stress element and finishing can be included, a restructuring cost can be reduced. The static loading test is enforced all 32 specimens. And several seismic retrofitting plans are explained as case studies. This seismic retrofitting method is effectiveness.
