项目摘要

The matters, which are clarified in the performance of this study, are as follows.1. By the collection of actual bridge test data for 6 modern timber bridges of the timber roadway bridges and the timber pedestrian bridges, this study clarified the structural performance on dynamic characteristics. Furthermore, it was conformed that impact factor was adopted the value of safe side, and there is especially no problem on vibration serviceability from understanding of the actual condition of the vibration of timber pedestrian bridge.2. As a result of investigating the application method to dynamic response factor in the Performance-based design code, it could present the performance type-impact factor code, which is reduced by span length.3. This study was investigated the three-dimensional dynamic response analysis of timber the highway bridge due to moving vehicles. As that result, it was constructed the dynamic response analysis method with the high accuracy between measured and analyzed vibration behavior values.4. The three-dimensional dynamic response analysis method of modern timber pedestrian bridge in which the pedestrian runs was formulated. In the analysis case of through arch timber pedestrian bridge, some differences have produced at analytic value and maximum value of experiment responsive wave shape, and that the accuracy of the analytic value is raised. That leaves as future problem.The performance code suitable performance-based design method of modern timber bridges was developed based on dynamic characteristic and structural performance when the synthetic and uniform structure performance was clarified.
在本研究的执行中澄清的问题如下。通过收集6座现代木桥的实桥试验数据,对木桥的动力特性进行了研究。通过对木结构人行天桥振动的实际情况的了解,确定了冲击系数采用安全侧值,特别是在振动适用性方面不存在问题.通过对性能化设计规范中动力响应系数的应用方法的研究,提出了按跨长折减的性能型--影响系数规范.本研究系探讨公路木桥在车辆移动作用下之三维动力反应分析。建立了振动特性实测值与分析值之间具有较高精度的动力响应分析方法.建立了考虑人行横道的现代木结构人行天桥三维动力响应分析方法。在下承式木结构人行桥的分析实例中,分析值与试验响应波形的最大值产生了一定的差异,提高了分析值的精度。在明确木桥结构性能的综合性和统一性的基础上,结合木桥的动力特性和结构性能,提出了适合现代木桥性能设计的性能规范。
