Multi-scale analysis of masonry walls
نویسنده
چکیده
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 require the definition of macroscopic constitutive laws. It is extremely difficult to build constitutive formulations which account for the above-mentioned phenomena and the material identification of such models models is costly. These drawbacks can be avoided by resorting to computational homogenization techniques and multi-scale approaches.

Multi-Scale Analysis of In-plane Behaviour of Tuff Masonry
Various methodologies are available today in engineering professional practice to analyse structures, in particular in the field of masonry structures. Many of the methods are derived from reinforced concrete frames but sometimes they suffer of lack of comprehensive experimental validation due to difficulties to simulate the many different kinds of masonries and they suffer from lack of critica...
متن کاملScaling 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 ...

A thin layer of ductile fiber-reinforced mortar material referred to as Engineered Cementitious Composites, or ECC has been experimentally investigated as a seismic retrofit for unreinforced masonry infill walls in non-ductile reinforced concrete frames. Compression tests of masonry prisms retrofitted with 13mm of ECC were conducted representing the compression strut of a masonry infill under i...
