摘要:
采用无损检测技术对古建筑木结构安全进行定量评价，对古建筑木结构维修和保护具有重要的现实意义。采用应力波测定仪FAKOPP对塔尔寺大金瓦殿的脊檩、檩、梁、承椽檩、房椽等五种木构件的动弹性模量进行了测定，结果表明应力波无损检测可以有效的测定残余木构件的力学强度，不同种类木构件弹性模量保持率与其承重作用大小相关。
Abstract:
Ancient timber structures or old building with wood structures are important cultural heritages to China and the world. It is very important to evaluate the safety of old wood structure members by nondestructive testing methods in old wood structures maintenance or protection. Modulus of elasticities (MOE) of five kinds of wood members including purlin on the ridge of the roof, square purlin, round purlin, beam, sprocket from Grand Hall of Golden tile, Kumbum Monastery located in Qinghai Province were measured by using stress wave method. Results showed that stress wave method was a reliable tool to evaluate the MOE of wood, and remaining dynamic MOE of old wood members had the positive relationship with timber structure position.
