ABSTRACT
Terrorism, with explosions both in and outside buildings, has become a significant
problem in the world. There are already several houses of unreinforced masonry, some of
which are historical. But under blast loading they do not function well. Retrofitting methods
have been developed to protect masonry buildings. Some research work has been carried out
in recent years to study the impact of retrofitted URM walls; these experiments require
usually significant time and funds. Also, with the attacks being carried out by Boko Haram
in Nigeria, a study is needed to check the behaviour of sandcrete masonry under blast loading
as it is widely used in Nigeria.
Unreinforced masonry walls are vulnerable to collapse when they are subjected to
explosives of out-of-plane and in-plane loads, as masonry houses were historically designed
with little to no consideration to the impact of explosive loads [1]. Because of the lack of
strengthening, many of these structures mostly fail in out-of-plane bending. In addition, the
key cause of death was found in the latest explosive attacks was unreinforced masonry
buildings (i.e. bursting into debris) [2]. In the field of structural engineering, the upgrade of
such structures has become a priority [3].
In order to mitigate out-of-plan bending, this study was conducted to develop and
test innovative fiber reinforcement techniques in the retrofitting of masonry walls. A model
was made using finite element analysis computer software called ABAQUS, to study the
behaviour of masonry wall subjected to the blast load. Also, CFRP material was applied to
the wall to improve the resistivity of the masonry wall to explosions and was modelled as
well to check if it’s has enough strength to withstand an explosive load.
