dc.description.abstract |
One of the main difficulties when working with heritage structures is the difficulty of
assessing the compressive strength of masonry and the other mechanical properties such
as the elastic orthotropic properties. In addition, actual masonry codes are focused on
modern fabrics which normally include Portland cement mortars. In fact, such mortars
are very different from the ancient ones, mainly based on aerial lime and sometimes
hydraulic lime. Then, in spite of knowing the properties of the bricks and mortar of
existing structures, architects and engineers are not able to obtain a good estimation of
the masonry mechanical properties because the values are below the range included in
the codes. In addition, obtaining mechanical properties from a full masonry specimen is
much more difficult than obtaining the characterization of the individual components.
The main objective of this Master Thesis is to obtain simplified expressions, similar to
those provided in standards such the Eurocode, to produce good estimations of the
mechanical properties of heritage masonry which include low strength mortars.
To this purpose, it is proposed to use systematically a numerical tool, based on analytical
expressions, able to compute the composite material properties of masonry from those of
the components, to produce a vast collection of results varying different parameters such
as the components' strength, young modulus, joint and brick sizes, etc. With this database
of results, validated with some existing experiments, simple closed form expression will
be adjusted to produce good estimators of these properties to the practitioners. |
