| Research Abstract |
This research project had been to study on seismic performance of 3-4 story wooden new frame structures. But, the 1995 Hyogo-ken Nanbu Earthquake caused a grate many and severe damage on slender and narrow wooden buildings. The aim of research had to be changed to seismic performance of these buildings.
The results of research are followings.
l)Survey on Deserter of Wooden Dwelling Structures due to the 1995 Hyogo-ken Nanbu Earthquake
The effective wall length ratio and eccentricity of arrangement of walls, and damage level are correlated.
2)Study on semi-rigid structures for slender houses
Several types of semi-rigid structures for slender houses were designed and examined by static loading tests.
3) Study on semi-rigid structures for large scale multi-story structures with glue laminated timber and plywood shear walls.
Several types of semi-rigid structures with plywood shear walls examined by static loading tests and analytical investigation by the parameter of opening of wall. The proposed analytica] methods are effective.
4)Study on ductility of these structures
The ductility properties of various types in wooden structures were showed and explained.
