Description
In order to make the houses aesthetically more appealing, different bond patterns are used in bonded masonry. This is mainly done in brick masonry. In some cases, walls are left unplastered to expose the brickwork bonded with different patterns. This paper presents a study on performance of commonly used bond patterns in Sri Lanka such as English, Flemish and Rat-trap. Indoor thermal performance of different bond patterns was assessed by measuring indoor and outdoor temperature using physical models. Rat-trap bond shows better thermal performance compared to the others. Computer models were validated with the results achieved from the experimental program. With all these findings, now the house builders, architects and engineers can select the masonry bond pattern suitable for their structures with the proper understanding of its performance.
