This is because the shear stress in a combined footing is usually high, and 6 legged stirrups are able to provide the necessary shear strength.<\/p>\n<p>Stirrups are a type of reinforcement that is used in concrete to resist shear forces.

The number of legs in a stirrup refers to the number of bars that are bent around the main reinforcement.<\/p>\n<p>The size and spacing of stirrups are determined by the shear stress in the concrete. The higher the shear stress, the larger and more closely spaced the stirrups need to be.<\/p>\n<p>In a combined footing, the shear stress is usually high because the footing is supporting a large load. This is why 6 legged stirrups are required in a combined footing if shear stress exceeds 5 kg\/cm2.<\/p>\n<p>Here are some additional details about the other options:<\/p>\n<ul>\n<li>Option B: 8
