The effect of axial force and shear force on the plastic moment capaci...
Effect of Axial Force and Shear Force on Plastic Moment Capacity
Axial force and shear force are two important factors that affect the plastic moment capacity of a section. Let us see how these forces affect the plastic moment capacity.
Effect of Axial Force on Plastic Moment Capacity
Axial force is the force that is applied along the longitudinal axis of the member. When an axial force is applied to a member, it induces additional stresses in the member which can reduce the plastic moment capacity of the section. The effect of axial force on the plastic moment capacity of a section is as follows:
- When the axial force is compressive, it reduces the plastic moment capacity of the section. This is because the compressive force increases the stress in the compression side of the section, which can lead to premature yielding and reduce the plastic moment capacity.
- When the axial force is tensile, it does not affect the plastic moment capacity of the section.
Effect of Shear Force on Plastic Moment Capacity
Shear force is the force that is applied perpendicular to the longitudinal axis of the member. When a shear force is applied to a member, it induces additional stresses in the member which can increase or decrease the plastic moment capacity of the section. The effect of shear force on the plastic moment capacity of a section is as follows:
- When the shear force is applied in the same direction as the plastic moment, it increases the plastic moment capacity of the section. This is because the shear force induces a shear stress in the section which adds to the bending stress and increases the plastic moment capacity.
- When the shear force is applied in the opposite direction as the plastic moment, it reduces the plastic moment capacity of the section. This is because the shear force induces a shear stress in the section which subtracts from the bending stress and reduces the plastic moment capacity.
Conclusion
In conclusion, axial force and shear force are two important factors that affect the plastic moment capacity of a section. Axial force reduces the plastic moment capacity of the section when it is compressive, while shear force increases the plastic moment capacity when it is applied in the same direction as the plastic moment and reduces it when it is applied in the opposite direction. Therefore, both axial force and shear force reduce the plastic moment capacity of a section.
