| Research Abstract |
In this research, two types of energy dissipation structural systems are developed in order to enhance seismic performance of wooden frame structures. The one makes use of an oil damper mounted as a knee-brace to increase absorbing energy of the structure. The other system dissipates seismic energy due to plastic deformation of wide flange shapes which is used to connect wooden beams and columns. Through a series of experimental and analytical studies, it is confirmed that both of the structural system can improve seismic response of wooden frame structures subjected to strong ground motions.
