U.S.-Czech Engineering Research: In-Situ Evaluation of Historic Wood Buildings

INT 0122251 Kasal北卡罗来纳州立大学的Bohumil Kasal和捷克理论与应用力学研究所的Milos Drdacky之间的这个美国-捷克项目以研究、实地研究和开发评估历史木结构的新方法为特色。所使用的技术将结合经典的无损方法、半破坏性方法、统计数据分析和模拟以及实验室验证。计划中的半破坏性方法测量机械和物理性能，包括使用取芯钻头取出微型木材试件，并评估压缩强度以测量弹性模数。非破坏性方法采用了应力波计时、电阻钻探和数字射线透视法。该团队的总体目标是系统地得出一种历史建筑的综合评估技术，有助于我们了解木结构结构的资产管理。这个涉及基础设施材料和结构力学的工程项目通过使美国和中欧的专家能够在相互感兴趣和能力很强的领域结合互补的人才和共享研究资源来实现促进科学知识的计划目标。

INT 0122251KasalThis U.S.-Czech project between Bohumil Kasal of North Carolina State University and Milos Drdacky of the Czech Institute of Theoretical and Applied Mechanics features research, field studies, and development of new methodologies for evaluating historic timber structures. The techniques used will combine classical nondestructive methods, semi-destructive methods, statistical data analysis and simulation, and laboratory verification. The planned semi-destructive methods measure mechanical and physical properties and involve removing micro- wood specimens using a core drill and evaluating compression strength to measure the modulus of elasticity. The nondestructive methods employ stress wave timing, resistance drilling and digital radioscopy. The team's overall goal is to systematically derive a comprehensive assessment technology for historic buildings that can contribute to our knowledge of asset management for wooden structures.This engineering project concerning infrastructural materials and structural mechanics fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Central Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence.
