Maximum permissible bearing stress (σ) is calculated as follows:
σ = 0.75fy
where fy is the yield strength of the material.
Explanation:
Bearing stress is the stress developed in a structural member when it is subjected to an axial compressive load. It is defined as the compressive force acting over the contact area between the two members.
The maximum permissible bearing stress is the maximum stress that can be developed in the member without causing failure. It is important to determine this stress to ensure the safety and stability of the structure.
The value of maximum permissible bearing stress depends on the material properties of the structural member. For example, the maximum permissible bearing stress for steel is different from that of concrete.
For steel, the maximum permissible bearing stress is calculated using the formula:
σ = 0.75fy
where σ is the maximum permissible bearing stress and fy is the yield strength of the steel.
The factor of 0.75 is used to provide a safety margin and to account for the uncertainties in the material properties and the load distribution.
It is important to note that the maximum permissible bearing stress should not be exceeded in the design of the structure, as it can lead to failure and collapse.
Conclusion:
The maximum permissible bearing stress for steel is 0.75 times its yield strength. This value is used in the design of steel structures to ensure their safety and stability.
