ABSTRACT

Cultural heritage buildings are valued in contemporary societies as they reflect the lifestyles and creative achievements our predecessors. For this reason, many countries have introduced regulations to ensure conservation of their historic buildings for the future, permitting minimal changes only to their original structure and characteristics. The key question addressed in this study is: how best can we assess the current structural behavior of a historical building, in particular wooden structures which may have survived for several centuries despite the deleterious consequences of decay, ageing and earthquakes? This paper focuses on a structural behavior assessment under current conditions (i.e. before restoration) of the Velipaşa Han Building, an impressive “caravanserai” or han (inn) building dating from the 19th century, in the central Anatolian region of Turkey. This assessment includes non-destructive tests to obtain the resistance of the timber structural elements and to determine the modal response of the building. In addition, a finite element model was developed, based on an on-site investigation and the proposed restoration project, and validated by consideration of in situ experimental measurements. The model also used a condition assessment of the building after proposed restoration. Through in situ inspection, experimental measurement and numerical investigation, the current structural behavior of the building was evaluated and, based on this, recommendations for intervention are presented in the study.

摘要

文化遗产建筑在当代社会受到重视，因为它们反映了我们前辈的生活方式和创造性成就。出于这个原因，许多国家出台了法规，以确保为未来保护其历史建筑，只允许对其原始结构和特征进行最小的改动。本研究解决的关键问题是：我们如何才能最好地评估一座历史建筑的当前结构行为，特别是木结构，尽管有腐烂、老化和地震的有害后果，但可能已经存在了几个世纪？本文重点介绍了 Velipaşa Han 大楼在当前条件下（即修复前）的结构性能评估，这是一座令人印象深刻的“商队旅馆”或 19 世纪的汉（客栈）建筑，在土耳其安纳托利亚中部地区。该评估包括非破坏性测试，以获得木材结构元件的阻力并确定建筑物的模态响应。此外，基于现场调查和拟议的修复项目开发了一个有限元模型，并通过考虑原位实验测量进行了验证。该模型还使用了拟议修复后建筑物的状况评估。通过现场检查、实验测量和数值调查，对建筑物的当前结构性能进行了评估，并在此基础上提出了干预建议。该评估包括非破坏性测试，以获得木材结构元件的阻力并确定建筑物的模态响应。此外，基于现场调查和拟议的修复项目开发了一个有限元模型，并通过考虑原位实验测量进行了验证。该模型还使用了拟议修复后建筑物的状况评估。通过现场检查、实验测量和数值调查，对建筑物的当前结构性能进行了评估，并在此基础上提出了干预建议。该评估包括非破坏性测试，以获得木材结构元件的阻力并确定建筑物的模态响应。此外，基于现场调查和拟议的修复项目开发了一个有限元模型，并通过考虑原位实验测量进行了验证。该模型还使用了拟议修复后建筑物的状况评估。通过现场检查、实验测量和数值调查，对建筑物的当前结构性能进行了评估，并在此基础上提出了干预建议。并通过考虑原位实验测量进行验证。该模型还使用了拟议修复后建筑物的状况评估。通过现场检查、实验测量和数值调查，对建筑物的当前结构性能进行了评估，并在此基础上提出了干预建议。并通过考虑原位实验测量进行验证。该模型还使用了拟议修复后建筑物的状况评估。通过现场检查、实验测量和数值调查，对建筑物的当前结构性能进行了评估，并在此基础上提出了干预建议。
