Impact of moister-temperature actions on character of behaviour of external layers of layered walls with flexible ties

Abstract

The article discusses influence of flexural ties on behaviour of external finishing-protective layer under the action of temperature-moisture movements. Forces and their distribution calculation results according to the finite element method in the external layer subjected to the action of temperature and moisture are presented. It is determined by investigations that even flexible ties restrain deformations imposed by temperature and shrinkage herewith tensile stress in the layer capable to cause its cracking.
