Abstract: This paper deals with an experimental investigation of the future environmental load on the medieval mosaic of the Last Judgement located at the entrance to St. Vitus cathedral in the Prague castle. The mosaic suffers from seasonal changes of the weather pattern including rains and their acidity, the deposition of dust and soot particles from polluted air as well as freeze-thaw cycles. These phenomena influence the conservation state of the mosaic. The tesserae composing the mosaic are mostly made from glass prone to weathering. In order to establish a procedure for an appropriate maintenance, the relation between various weather scenarios and their effect on the mosaic was investigated. At the same time a local method for evaluating a suitable protective coating was developed. Both methods will contribute to better care for the mosaic and also to improve visitors’ aesthetical experience.

Abstract: Non-linear finite element method (FEM) allows to take into account material and geometrical non-linearities in the simulation of the behaviour of reinforced concrete structures. However, the accuracy of the numerical solution with respect to experimental tests is often questionable, especially in the case of 2D and 3D structures. Several competitions showed in the past significant scatter of the predicted results with respect to the correct ones. Even though internationally well-known computer softwares can be used to predict the structural response, the uncertainty of the numerical simulation cannot be neglected. Therefore, the application of finite element models to the assessment of concrete structures requires a proper investigation of the uncertainty related to the results of the simulations. This paper presents a comparison of numerical simulations of sixteen case studies taken from past experimental tests and modelled with three commercial non-linear softwares. The purpose of th
