The objectives of this study are a)diagnaostic inspection of deterioration of the Sanctuary of Vicoforte and some related historical structures by visual observation and non-destructive tests, b)structural and dynamic investigation, and c)interpretation of the static and dynamic behaviors of the dome by FEM. This work is a part of the surveying project "Vicoforte 2002-2006" as a joint research between Japanese and Italian scholars of Politecnico di Torino.1.Delamination of stone finishing and fresco painting are detected by visual observation and Radiation Thermometer.2.The thickness of the main dome and vaults are estimated by Electromagnetic Radar.3.Impact Echo Scanner is applied to estimate the continuity of iron ties embedded at the base of the main dome and they are probably continuous.4.Concrete Test Hammer, Scratch Tester, Simple water absorption test, Windsor Pin System are applied to estimate the compressive strength and Young's modulus of the brick and the mortar. Estimation of durability for the brick and the stone by Freezing and thawing method are also applied.5.From the microtremor measurement, the fundamental frequency of the dome is estimated.6.The load bearing mechanism and crack pattern of the structure are clarified by FEA.7.Non-destructive tests are applied to diagnostic inspection of deterioration of the chapel of Sindone and airship Hangar and from the microtremor measurement, the fundamental frequencies are estimated.8.Monitoring of temperature, inclination of the wall, cracks, and tension of the wire of he Hangar are started.9.Diagnostic inspection of deterioration of Rakanji stone arch bridge, Oita, and the brick chimneys, Tokoname, are carried out and from the dynamic test, natural frequencies and modes are estimated. Earthquake resistance efficiency of the brick chimneys is evaluated. Dynamic test of the traditional timber temples are also carried out and their dynamic characteristics are clarified.

本研究的目的是a）通过目视观察和非破坏性测试对Vicoforte圣殿和一些相关历史结构的恶化进行诊断检查，B）结构和动力调查，以及c）通过有限元法解释圆顶的静态和动态行为。这项工作是“Vicoforte 2002-2006”测量项目的一部分本文是意大利都灵理工大学的日本学者和意大利学者合作的一项研究。1.通过目视观察和辐射温度计检测石材饰面和壁画的分层; 2.通过电磁雷达估计主穹顶和拱顶的厚度; 3.通过冲击回波扫描仪估计铁结的连续性4.采用混凝土试锤、划痕仪、简易吸水率试验、温莎销系统等方法测定了砖和砂浆的抗压强度和杨氏模量。5.通过对结构的微动测试，确定了结构的基频; 6.通过有限元分析，明确了结构的受力机理和开裂形式; 7.对Sindone教堂和飞艇机库进行了无损检测，并通过微动测试，对结构的耐久性进行了分析。8.开始监测机库的温度、墙体倾斜度、裂缝和钢丝张力。9.对Rakanji石拱桥大分和砖烟囱常滑的劣化进行诊断检查，并根据动态测试估计固有频率和模态。对砖烟囱的抗震性能进行了评价。并对传统木结构寺庙进行了动力测试，阐明了其动力特性。
