Size Dependence of Strength and Fracture Properties of Brick Masonry
The test data on the size effect in the failure of masonry walls and some parts of the discussion of size effect are valuable. However, the theoretical description of the size effect is in my opinion invalid. The use of the "multifractal scaling law" proposed earlier by the senior author is unjustified, for the same reasons as it is for concrete structures. The reasons are explained in detail i...
متن کاملEffective stiffness of unreinforced brick masonry walls
Code design of Unreinforced Masonry (URM) buildings is based on elastic analysis, which requires as input parameter the effective stiffness of URM walls. Current approaches estimate the effective stiffness as fixed ratio of the gross sectional stiffness but comparisons with experimental results have shown that this does not yield satisfactory predictions. In this paper, a recently developed ana...
متن کاملPeak and residual strengths of brick masonry spandrels
Unreinforced masonry (URM) walls comprise vertical piers and horizontal spandrels, which together form the lateral load resisting system. Whereas past research yielded significant advances in the understanding of the force–deformation characteristics of masonry piers, knowledge of the behaviour of masonry spandrels is lacking. This paper makes a contribution to our understanding of the seismic ...
متن کاملseismic analysis of persian historical brick masonry minarets
according to high height and weak tensile strength of materials in minarets, it is necessary to study the structural behaviour of minarets under earthquake loading. therefore nine historical brick masonry minarets in isfahan have been modelled and analysed by applying the nonlinear finite element method for two cases: 1) the whole minaret, and 2) only the outer shell. results show that all mina...
متن کاملCompressive behaviour of brick masonry triplets in wet and dry conditions
Mechanical behaviour of old masonry may differ from the theoretical one to a great extent, hence it needs to be properly evaluated for quantifying the safety and serviceability of real structures, in view of their rehabilitation and/or seismic reliability assessment. Among the factors affecting such behaviour, the presence of moisture, mainly from rising damp, plays a key role in the deteriorat...
