A Method for Assessing The Risk Level of Monumental Historical Structures by Visual Inspections

摘要

Safety assessment based on qualitative and- quantitative data is necessary before making any intervention decision. The qualitative data is visual inspection of structural damages, decays and deteriorations and the quantitative data requires laboratory tests, structural analysis etc. Obtaining the quantitative data is detailed method which necessitates specialists and takes more time and money. The fact that there are so many historical buildings and few specialists on this field it is very important to develop quick methods for assessing the risk level of those structures.There are codes for designing earthquake resistant structures and check lists for evaluating the. risk level especially for recent structures. But pre-hazard risk assessment of historical structures and monuments is not common. The aim of this paper is to present the method based on visual inspection for classifying' the risk level of the historic monumental masonry structures. According to the result of the evaluation the buildings underhigh risk can be oriented to the specialists.
