Abstract—The paper deals with the nonlinear computational modeling of the baroque enclosure masonry walls. The main tasks are input parameters for efficient advanced numerical tools and techniques, which are based on nonlinear and quasi brittle constitutive FEM modelling.  For the work was used the knowledge and results from the Broumov Group Churches survey acquired in the frame of international SAHC university cooperation.  There are presented nondestructive tests, comparing with laboratory ones. The goal of the contribution are real bearing capacity parameters of the composite enclosure walls, which leads from standard homogenization techniques.
