Beam Curved in Plan Design

Bending Moment and Shear are the two main forces that are considered while designing a beam curved in plan. This is because when a beam is curved in plan, it experiences uneven loading and bending moments due to the varying radius of curvature along its length.

Bending Moment

Bending Moment is the force that causes the beam to bend or deform. It is calculated as the product of the force applied and the distance from the point of application to the fixed end of the beam. In the case of a curved beam, the bending moment varies along the length of the beam due to the varying radius of curvature.

Shear Force

Shear Force is the force that causes the beam to shear or cut. It is calculated as the difference between the forces acting on either side of the section being considered. In a curved beam, the shear force is also affected by the varying radius of curvature.

Importance of Designing for Bending Moment and Shear

Designing a beam curved in plan for bending moment and shear is important because it ensures that the beam can withstand the forces acting on it without failing. Failure of a beam can lead to catastrophic consequences, such as collapse of a structure or injury to people.

Conclusion

In conclusion, a beam curved in plan is designed for bending moment and shear because these are the two main forces that are affected by the varying radius of curvature. Designing for these forces ensures that the beam can withstand the forces acting on it and prevent failure.
