FUNDATION EXPERIMENTS RESEARCH OF NEW ANGLE- DISPLACEMENT DAMPER FOR WOOD FRAME STRUCTURES IN RURAL AREAS

In this study, a new Angle-displacement Damper suitable for the wood frame buildings in rural areas is designed on the analysis of destroying mechanism of wood frame buildings under earthquakes. Its structure and working principle are also given. The variety laws of several function parameters of this damper in different temperatures, loading frequencies and controlling displacements has been analyzed through mechanical experiments and a low cycle fatigue test. It is proved that this damper has good deformation capacity, energy dissipation and anti-fatigue performance.
