This paper investigates the thermomechanical behaviour of historical masonry structures subjected to high temperatures. The finite element code NOSA–ITACA, developed at ISTI–CNR and devoted to model structures constituted by masonry materials with temperature-dependent tensile and compressive strengths and Young’s moduli and subjected to thermal loads, is used to model the static and dynamic behaviour of a masonry railway tunnel.

摘要

This paper investigates the thermomechanical behaviour of historical masonry structures subjected to high temperatures. The finite element code NOSA–ITACA, developed at ISTI–CNR and devoted to model structures constituted by masonry materials with temperature-dependent tensile and compressive strengths and Young’s moduli and subjected to thermal loads, is used to model the static and dynamic behaviour of a masonry railway tunnel.
