| Research Abstract |
The objective of this study is to clarify structural mechanics of wooden structures by experimental approaches and theoretical analyses of wooden unit frames and full-scale wooden structures.
(1)Evaluation of seismic performance of wooden frames
To evaluate the seismic performance of wooden buildings, shaking table tests and static loading testes of wooden unit flames installing various bearing elements were carried out. The dynamic properties and restoring force characteristics are investigated. From these experimental results of restoring force characteristics, nonlinear identification methods to determine the analytical models of hysteretic characteristics are developed The structural analysis and seismic response analysis of uncertain structural systems are developed.
(2)Clarification of structural mechanism of traditional wooden structures
The structural mechanisms of traditional wooden frame are characterized by bending moments of column-tie beam joints and restoring force characteri

stics due to column rocking. To clarify these mechanisms, the shaking table tests and static loading tests using structural elements and full-scale models of traditional wooden frames were carried out. The size effects of column and beam on the restoring force are investigated. These results are applied to the seismic design and retrofit methods for traditional wooden buildings.
(3)Development of seismic and enhancement design methods for wooden buildings
The evaluation methods of dynamic and static seismic performance for wooden flames through the shaking table tests and static loading tests of unit frames installed various bearing elements are developed. These experimental data such as bearing capacity-deformation relationships are prepared as data for seismic design. A simple method "response-limit capacity analysis" to evaluate the seismic performance of wooden frames is proposed The proposed method enables us to trace the bearing rapacity-deformation relationships of wooden flame in wide range of deformation and easily to estimate the maximum displacement response by using seismic response spectra. The proposed method is applied easily to the enhancement design of old wooden houses by vibration control devices as well as the seismic design of new houses. Less
