Stress in the building components could be caused by externally applied forces such as dead, live, wind, seismic loads, foundation settlement, or induced internally due to temperature variations, moisture changes, and chemical actions. Cracks affect the building’s artistic look, and it destroys the wall's integrity, affects the safety of the structure, and even reduces the durability of the structure.
