Shear Failure in General:
Shear failure is a type of failure that occurs in soils when the shear stress exceeds the shear strength of the soil. It typically occurs along a failure plane or surface within the soil mass. In general shear failure, the failure surface is continuous and develops between the edge of the footing and the ground surface.
Explanation:
When a load is applied to a footing or foundation, it induces shear stress in the soil. The shear stress is transmitted through the soil, and if it exceeds the shear strength of the soil, shear failure occurs. In the case of general shear failure, the failure surface is continuous and extends from the edge of the footing to the ground surface.
Reason for Continuous Failure:
The reason for continuous failure between the edge of the footing and the ground surface is that the shear stress is highest at the edge of the footing. As the load is applied, the soil at the edge of the footing experiences the maximum shear stress, and if it exceeds the shear strength of the soil, failure occurs. This failure then propagates along a continuous surface towards the ground surface.
Importance of Edge of the Footing:
The edge of the footing is a critical location in terms of shear failure because it experiences the highest shear stress. The stress distribution in the soil is not uniform, and the maximum shear stress occurs at the edge. Therefore, it is important to consider the edge of the footing when analyzing and designing foundations to ensure that shear failure does not occur.
Conclusion:
In general shear failure, continuous failure develops between the edge of the footing and the ground surface. This is because the shear stress is highest at the edge of the footing, and if it exceeds the shear strength of the soil, failure occurs. Considering the edge of the footing is crucial in foundation design to prevent shear failure.
