Possible Causes of Cracks at Klang Mosque

This research project is focused on the evaluation and assessment of cracks appeared in
the structural members of Klang Mosque. There are many diflerent kinds of cracks that
sometimes are not serious and are probably due to shrinkage of concrete. Thus, in order
to find out whether the cracks are because of serious causes such as settlement or design
fault, the crack has to be identified and the causes must be studied in order to prevent
building failure from likely to happen.
In order to determine the possible causes of cracks this study is based in three levels. In
the first level, site inspection was made and cracks were physically inspected and were
mapped out on sketches, the information included the orientation location and size of
cracks. In the second level of assessment structural analysis and design of cracked
elements is made and it is compare with the actual design in order to determine whether
the design short falls caused any cracks. Inthe third level some NDT (non-destructive
test) is to be performed in order to assess the quality of work and properties of in-situ
materials such as concrete.
