Calculation of the load-bearing capacity of the brickwork fragment with uncertainty high degree in the materials properties

摘要

The mechanical properties of brickwork depend on a multitude of different factors such as components properties, their specific volume content, relative location and the quality of adhesion bonds. An important feature of the masonry is the high degree of these factors indeterminacy and the wide scatter of the experimental data in the testing of bricks and mortar. We present a mathematical model that allows determining the mechanical characteristics of the masonry based on the mechanical properties of the brick and mortar, their specific volume content in a fuzzy setting in this paper. All input parameters, which allow to obtain interval estimates of stresses and deformations of the brickwork fragment, are determined by membership functions. The simulation results are compared with the experimental data of other authors.
