Features of information modeling of cultural heritage objects

Abstract

This paper focuses on features of heritage objects information modeling and its integration with structural analysis under various types of impacts. We discuss different results of structural analysis based on finite element model (FEM) of the New Hermitage portico. Thanks to laser scanning technology it was possible to collect all the geometric features of this object and generate an adequate mathematical model based on the obtained data. The methodology of finite element model creation based on laser scanning and BIM technologies is proposed. Some interesting results of laser scanning survey and numerical modelling have been discussed. Deviations of the portico's structural elements have been identified based on the use of laser scanning, BIM and FEA. It has been found out that the displacement of the upper parts of the columns relative to the lower ones in the direction of the facade wall is 4 cm. An intermediate HBIM of the portico (LOD 100) has been created inside Revit. Finite element model with default element size of 300 mm has been created using ANSYS. Directions for further research have been also determined.
