项目摘要

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 framesTo 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 structuresThe structural mechanisms of traditional wooden frame are characterized by bending moments of column-tie beam joints and restoring force characteri … More 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 buildingsThe 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

本研究的目的是通过对木单元框架和全尺寸木结构的实验方法和理论分析来阐明木结构的结构力学。(1)木框架的抗震性能评价为了评价木结构建筑的抗震性能，进行了振动台试验和安装各种承载元件的木单元框架的静载试验。研究了动态特性和恢复力特性。根据这些恢复力特性的实验结果，开发了非线性识别方法来确定滞回特性的分析模型。开发了不确定结构系统的结构分析和地震响应分析。(2)阐明传统木结构的结构机制传统木框架的结构机制以柱系梁节点的弯矩和柱摇摆引起的恢复力特性为特征。为了阐明这些机制，使用结构元件和传统木框架的全尺寸模型进行了振动台试验和静载荷试验。研究了柱和梁的尺寸对恢复力的影响。这些成果应用于传统木结构建筑的抗震设计和改造方法。(3)木结构建筑抗震和加固设计方法的发展通过振动台试验和安装各种承载元件的单元框架的静载试验，建立了木结构动、静抗震性能评价方法。这些实验数据例如承载力-变形关系被准备作为抗震设计的数据。提出了一种评估木框架抗震性能的简单方法“响应极限能力分析”。该方法使我们能够追踪木框架在大变形范围内的承载能力-变形关系，并利用地震反应谱轻松估计最大位移响应。该方法很容易应用于旧木结构房屋振动控制装置的增强设计以及新建房屋的抗震设计。较少的
