Deep beams are designed for:
Deep beams are structural elements that are designed to resist both shear force and bending moment. They are typically used in situations where the span-to-depth ratio is small and the applied loads result in significant shear forces and bending moments.

Shear force:
Shear force is the force that acts parallel to the cross-section of a structural element. It tends to cause the element to slide or shear along a plane. In deep beams, shear forces are a major concern because of their large magnitude and their potential to cause failure. The shear force in a deep beam is resisted by the shear capacity of the beam, which is determined by the concrete and reinforcement strength, as well as the geometry of the beam.

Bending moment:
Bending moment is the moment that causes a structural element to bend or rotate. It is a result of the applied loads and the distance from the neutral axis of the beam. In deep beams, bending moments are also a significant design consideration. The bending moment capacity of a deep beam is determined by its flexural strength, which depends on the concrete and reinforcement properties.

Combined effect:
Deep beams experience both shear force and bending moment simultaneously. The interaction between these two forces is complex and requires careful design. The design of deep beams involves determining the required reinforcement in order to resist both shear and bending.

Bearing:
The option 'd) Bearing' is incorrect because bearing refers to the area or surface that supports a load. It is not directly related to the design of deep beams.

In conclusion, deep beams are designed for both shear force and bending moment. The design of deep beams requires careful consideration of the interaction between these two forces and the appropriate reinforcement to resist them.
