Factors Affecting the Accuracy of Computations of Historic Structures

Abstract

Possible approaches to the computation of historic structures and factors affecting the precision and accuracy of the results are presented in the paper. The degradation of building materials or incorrectly done technical and historical surveys affect the data entered into a numerical computation. The complexity of the model or, on the other hand, a significant simplification of the model can lead to the misinterpretation of the results. It is necessary to know what is calculated and be able to decide if the simplification of the numerical model does not entail the achievement of results with large reserves, for example, in the load-bearing capacity of the structure. On the contrary, the complexity of the model can result in its illegibility and potential mistakes in determining the contacts. It can easily happen that, for example, one element in the numerical model of a complex historic roof supports a different one, but, in fact, the opposite is true. The article presents specific examples of structures on paper and possible variations in the results obtained by considering the relevant factors. The results will be mutually compared for transparency.
