- Description
- This paper describes the development of a computational model for masonry that will be used to
study different strengthening systems for single leaf brick wall panels containing openings. As many
of the brickwork walls in need of strengthening were constructed of low strength materials or they
have deteriorated with time, cracking tends to be along the brick/mortar interfaces and failure usually
results from de-bonding of the bricks. As a result the authors decided to use a computational model
based on the Distinct Element Method which was developed by Cundall [1] in 1971. The method was
developed for commercial use by Cundall and Itasca Limited [2] for 2-dimensional structures in the
form of the software UDEC (Universal Distinct Elements Code). Initially DEM was applied to rock
engineering projects where continuity between the separate blocks of rock did not exist. More recently
it has been used to model masonry structures [3, 4 and 5] in which the failure mechanism is governed
primarily by the masonry unit/mortar interface characteristics.

- Mechanical properties of clay brick masonry bound with hydraulic limes and hydrated calcium lime

- Description
- Due to their physical and chemical properties, mortars made with lime are considered to be more
compatible with historic fabrics than those made with artificial cements. This paper explores the
mechanical properties of clay brick masonry bound with hydraulic limes of different strengths, and
hydrated calcium lime (CL90-s) with no hydraulic properties. Masonry wallettes built with a CL90-s
mortar and two natural limes of hydraulic strengths 3.5 and 5 MPa (NHL 3.5 and NHL 5) respectively
were tested for compressive and flexural strength. The strength of the bond between the mortar and
the brick was also measured. The paper concludes that CL mortar masonry displays a plastic
behaviour in compression while the mechanical behaviour of the HL mortar masonry is of a brittle
nature, with wallettes splitting along the centre, cracks above and below the vertical joints and spalling
of brick and mortar.
It also concludes that neither the rate of late strength gain of masonry, nor its ultimate compressive
strength or its bond strength are determined by the mortar nature, thus a mortar of low hydraulic
strength can provide stronger masonry than an emminetly hydraulic mortar. The paper agrees with
previous authors on that the masonry’s compressive strength is more sensitive to the brick-mortar
bond strength than to the compressive strength of the mortar. Finally, the paper demonstrates that the
NHL-mortar compressive strength increases at a higher rate, and reaches higher final values than
that of the NHLmasonry whereas, in contrast, the CL90-s mortar is weaker in compression than the
CL90-s mortar masonry.

- Description
- Possible method for seismic vulnerability assessment of masonry structures with special attention
to low-rise residential structures in Macedonia is proposed in this paper. For this purpose, special calculation
tool which contains specific knowledge for masonry structures derived by numerical calculations and analyses
is developed. The aim of this assessment tool is to be simple for application even for personnel with slight or no
experience in behaviour of masonry structures under seismic action, so it could be developed as a serious system
for fast and precise assessment of the condition of many structures in a wide region. In this paper, a numerical
model for calculation of the bearing capacity of the structure based on the discrete element method is suggested,
so that it is first application of this relatively new numerical technique for calculation of masonry in Macedonia.
A method for creation of the knowledge base for an Expert System suggested by the given methodology is
presented. Also, results from the application of this methodology are applied on a real structure.
