Abstract

The structural assessment of historical monuments is a challenge to engineers because current construction techniques use different systems and materials. Engineers are not trained to design massive structures that use structural elements made of stone and/or brick. The assessment requires a multidisciplinary team in order to understand the original construction, look for evidence and records for modifications throughout the life span of the structure and document deterioration due to environmental conditions. This requires knowledge of the monument history, use, geometrical dimensions of structural elements, defects and/or inclinations. Thus, feedback from the historian, architect, surveyor, materials and geotechnical engineer is required. Finite element modelling is typically used to predict the behavior of the different structural elements. Sometimes simple two dimensional models are sufficient to present the performance of the structure and other times three dimensional models are necessary. Model verification is an integral part of the analysis and is usually done by field measurements. For some structures, it is useful to perform free vibration measurements to determine the natural frequencies and use the measured values to tune the finite element model parameters. The mechanical properties of the construction materials as well as the soil under the foundation are key parameters that define the overall behavior of the structure.
