Seismic performance evaluation on historical timber frame structures with large hanging walls

a) Specimens of which walls break before breakage of columns have high deformation performance. b) Different specification of hanging walls and size of column section give different failure mechanism and bearing force of hanging walls. c) Ratio of shear force of columns given by the results of tests is different from the ratio based on the current code. d) Bearing force of hanging walls is varied by specification of frames such as section size of columns and thickness of crosspieces called Nuki. e) Rear columns are broken at the bending unit stress which is about the half of the flexural strength.
