Abstract
This paper includes the most important findings of a series of linear analyses
focusing on the development of failure that is identified through different failure
criteria. The historic monument which was selected for this investigation is the
church of Agia Triada, in the District of Karditsa, Greece. The numerical
simulation for the church of Agia Triada includes all parts of the super-structure
and considers the effects of vertical and earthquake loads. The main objective of
this paper is to predict the initiation of failure at various structural elements
considering a) a Mohr-Coulomb failure criterion with a limit on tension strength
and b) modified Von Misses failure criterion. These two failure criteria are
applied for the same structure and for the same load combinations. The predicted
by the two failure criteria initiation of failure and the corresponding failure areas
are compared and discussed.
Keywords: historic monuments, numerical investigation, Mohr-Coulomb,
modified Von Misses.
1 Introduction
Masonry is a material that presents considerable difficulty in assigning values of
mechanical properties or adopting failure criteria. Different simulation strategies
can be applied depending on the scale needed for the examination of the
initiation of failure in the masonry. Micro-modeling of the masonry, where units
and mortar joints are simulated separately, together with appropriate failure
criteria is a popular approach in successfully predicting failure areas in masonry
components. However, it is very computationally demanding to be directly
applied in large structures, especially those with considerably complicated
