ABSTRACT

The present paper focuses on the application of the yield line method to estimate the pressure bearing capacity of laterally loaded masonry walls. The characteristics of the function of bending moment coefficient are given first to assess the results of numerical analysis and the proposed methods in literature. The shortcomings of applying the yield line method on masonry are discussed and a proposal for the possible modifications is given, based on the length of the first crack. The numerical simulation has been performed to follow the progression of cracks up to the point of collapse. Primarily, two kinds of masonry walls have been considered through the study: (a) Masonry walls which show no crack through the units, and (b) Masonry walls which show cracks through the units. The numerical results have been compared with the proposed modification on yield line method to give a clear explanation of the behaviour and to determine the critical factors that influence the pressure bearing capacity.

KEYWORDS: bending moment coefficient, critical aspect ratio, lateral loading of masonry, numerical simulation, out-of-plane failure, yield line method
