Experimental And Numerical Study Of The
Long-term Behaviour Of Ancient Masonry
Author(s)

Abstract
A study on the time dependent behaviour of the masonry coming from the XVI
century crypt of the Cathedral of Monza (Italy) will be described. The simulation
of the observed behaviour by a visco-elastic rheological model, including
damage variables, will be presented for a subsequent application to construction
analysis.
Keywords: ancient masonry, creep, viscoelasticity, damage.
1 Introduction
The time dependent behaviour of ancient masonry buildings, often characterized
by non-homogeneous load-bearing sections, is considered among the factors
affecting their structural safety. Together with other synergetic aspects, this
proved to be involved in the collapse of some monumental buildings occurred
during the last fifteen years.
Exploiting the material coming from different ancient structures, several
experimental procedures have been adopted to understand the phenomenon, from
creep to pseudo-creep tests, and various rheological models have been applied to
interpret the results [1]. Here a study on material taken from the crypt of the
Cathedral of Monza (Italy) will be described, and the simulation by a viscoelastic
rheological model, incorporating damage effects, will be presented.
2 Provenance of the tested material
After the plane rearrangement of the Museum of the Cathedral of Monza in
1994, the removed material, resulting from a door opening on the northern wall
of the crypt, was collected for experimental testing. According to the historical
Keywords
ancient masonry, creep, viscoelasticity, damage.
