  • Computational modelling of laterally loaded masonry walls as a part of support activities for the evaluation of slovenian national parameters for Eurocode 6 [Elektronski vir]
    Bosiljkov, Vlatko
    Slovenia is one of the last EU country that have adopted National document for the application of Eurocode 6 [6]. This process in Slovenia lasted almost ten years since there were major disputes ... among researchers regarding the interpretation of the analytical formulation for the calculation of lateral resistance of masonry walls according to EC-6 provisions and its efficiency in prediction of experimentally obtained results on walls tested in laboratory conditions. In order to clarify critical states of stresses within masonry components during experimental tests a simplified micro-modelling strategy [1] was chosen and applied in modelling masonry. Comparison of computed behavior of masonry with experimentally obtained results of laterally loaded masonry walls of different aspect ratios and tested under different levels of precompression corresponded well both in overall behavior as well as it concerns obtained mechanisms of failure. Failures of masonry components where either due to exceeding compressive, tensile or shear stresses in critical (bottom) cross-section of tested specimens depending from their aspect ratio and levels of precompression. Numerical study also revealed considerable stress redistribution within the masonry in its softening region that may mislead to the conclusion that critical cross-section for the calculation of lateral resistance should be considered at the middle height of the specimen [3]. In addition to this study further analytical calculations provided limiting values for characteristic shear strength of the masonry in dependence from type of head joints and limiting maximum value for shear strength in Slovenia at 1.4. MPa.
