Tube-Jack Testing for Irregular Masonry Walls: Regular Masonry Wall Testing

Senior Project: Masonry Core Testing

Testing unreinforced masonry structures at reduced scale

When testing multi-story structures on a shaking table, most testing facilities require a reduced scale model. Producing scale test units at small scale is particularly challenging for unreinforced masonry structures. Previous work by other researchers showed that scaling of units and mortar joints is mandatory in order to obtain for the reduced scale masonry failure modes, which are similar to...

Homogenization of Interlocking Masonry Walls

In a previous publication the authors proposed a continuous model for describing the mechanical behaviour of ‘Running Bond’ masonry walls. Here a different masonry structure is considered. This structure is ‘bi-atomic’ in the sense that its pattern consists in two kind of blocks with different. The homogenization by differential expansions technique is used for obtaining an equivalent Cosserat ...

Scaling unreinforced masonry for reduced-scale seismic testing

When testing multi-storey structures, most testing facilities require the testing of a reduced-scale model. A literature review on tests of scaled masonry structural components revealed that scaling of masonry was rather challenging and often significant differences in stiffness, strength and failure mechanisms between the different sized masonry were reported. This paper addresses the scaling ...

Multi-scale analysis of masonry walls

Masonry is a heterogeneous structural material which exhibits a complex behaviour with potential cracking in each of its phases. Its structure (geometrical arrangement of mortar joints, quasi-brittle constituents) causes the appearance of complex composite failure modes with loading path dependence and strong damage-induced anisotropy effects. Large scale computations for masonry structures req...
