NON-LINEAR ANALYSIS OF SLENDER MASONRY COLUMN SUBJECTED TO BIAXIAL BENDING

The article deals with a method for analysing slender masonry columns. proposed uses material and geometric non-linearity. Various stress-strain diagrams can be used: linear, linear-plastic, parabolic-plastic, two various parabolic rigid-plastic. In all cases, the tensile strength is neglected. used column in accordance Eurocodes ways: SLS (serviceability limit state) ULS (ultimate state). internal forces are calculated on general beam model, imperfections both directions, which result bending moments perpendicular planes – biaxial bending. This case not covered by current code Eurocode, even though columns more or less loaded directions. this numerical study, using Matlab software, an algorithm was developed modelling real 3D case. results of study also compared to laboratory tests
