Brick masonry is one of the most commonly used materials for the construction
of single and two storied buildings. There is a need to understand its behaviour
under the action of c loads and obtaining the natural frequency and mode shapes
of such structure is the first step towards it.
Since the response of the structure is mainly influenced by the properties of the
constituent materials used, which varies largely from place to place, there is a
need to study the behaviour of masonry structures made of locally available
materials. The information regarding 'frequency analysis of masonry buildings
is scant.
In this dissertation work, a parametric study of the frequency analysis of simple
brick masonry structures has been done by idealizing masonry as an orthotropic
material. It is obvious that for complicated wall layout the analysis would
become difficult, hence frequency analysis of masonry walls with different
boundary conditions has also been done. An attempt has been made to correlate
the wall frequencies with building frequencies.
The effect of openings, boundary conditions, roof and its influence on the mode
shapes has been discussed in detail
