| Abstract |
The long span and large-scale timber structures are requested to promote the wood demand. It is necessary to develop and verify a new structural system to achieve a medium rise building using wooden structure. This research deals with high-performance laminated timber-based composite members, which consist of structural laminated timber and H-beam. We performed T shaped beam-to-column joint tests to investigate the strength, stress distributions of laminated timber and failure patterns under cyclic loading. The specimens of 4 types(classical wooden joint with bolts and steel plate, joint inserting H section steel into laminated timber, joint stiffened by epoxy between H section steel and laminated timber, and joint stiffened by bolt(M24) between web of H section steel and laminated timber). The results of the test show that the specimen having inserting length of 2 times of the H section steel beam height was characterized by fairly good strength and stiffness than those of the classical wooden joints. And, the hysteresis characteristics is very stable and also confirmed the high level of an energy absorption performance. |
