Since wall in RCC structure is not load bearing elements. They are just infilled walls and satisfy many other needs.
Vertical cracks occur when long brick walls are built tightly between RCC Column. The brickwork is compressed and buckled due to thermal and moisture expansion. Furthermore, a small amount of linear movement in the long brick panel can also produce a bulge in masonry.
