| Summary: | 碩士 === 國立成功大學 === 建築學系碩博士班 === 94 === In Taiwan , the bamboo-mud-wall is the main structural element of most of the existing wooden historic buildings . For investigating the structural behavior of the bamboo-mud-wall , in this study , totally 13 specimens including different construction , different material , and different height-to-width ratio are tested under horizontally cyclic loading .
From the test , followings are observed :
1. Under the cyclic loading , the specimen gets compression failure at the corner first , then suffers shear failure of the wall panel .
2. The ultimate load of the wall specimen is influenced by the arrangement of horizontal and vertical Nuki (complemenyary member) .
3. In the wall specimens , in general , the wooden frame provides 1/3 strength , and mud provides 2/3 strength .
4. The recorded hysteresis loop of the wall specimens can be simplyfied as several rules. Following these rules, the load-displacement relationship of the bamboo-mud-wall under cyclic loading or time history loading can be generated .
In addition , for assessment application , an eguivalent bracing model of the bamboo-mud-wall is established based upon the test results . This study provides the conservation designer or architect the fundamental informations for seismic evaluation and retrofit design of wooden historic building.
