Shear Friction Factor

Go Shear Friction = ((Coefficient of Friction between Two Surfaces*Total Vertical Force)+(Base Width*Average Shear of Joint))/Horizontal Forces

Maximum Height in Elementary Profile without Exceeding Allowable Compressive Stress of Dam

Go Minimum Possible Height = Allowable Compressive Stress of Dam Material/(Unit Weight of Water*(Specific Gravity of Dam Material-Seepage Coefficient at Base of Dam+1))

Minimum Vertical Direct Stress Distribution at Base

Go Minimum Vertical Direct Stress = (Total Vertical Force/Base Width)*(1-(6*Eccentricity of Resultant Force/Base Width))

Width of Elementary Gravity Dam

Go Base Width = Height of Elementary Dam/sqrt(Specific Gravity of Dam Material-Seepage Coefficient at Base of Dam)

Max Vertical Direct Stress Distribution at Base

Go Vertical Direct Stress = (Total Vertical Force/Base Width)*(1+(6*Eccentricity of Resultant Force/Base Width))

Maximum Possible Height when Uplift is Neglected in Elementary Profile of Gravity Dam

Go Maximum Possible Height = Allowable Compressive Stress of Dam Material/(Unit Weight of Water*(Specific Gravity of Dam Material+1))

What is Sliding in Friction?

We can define sliding friction as the resistance created by any two objects when sliding against each other. This friction is also known as kinetic friction and is defined as the force that is needed to keep a surface sliding along another surface.

What is the Factor of Safety due to Sliding of the Retaining Wall?

The factor of safety against sliding should be about two. 3 Bearing on Ground - The normal pressure between the base of the wall and the soil beneath can cause a bearing failure of the soil, if the ultimate bearing capacity is exceeded. Usually the allowable bearing pressure will be one-third of the ultimate value.

How to Calculate Sliding Factor?

Sliding Factor calculator uses Sliding Factor = Coefficient of Friction between Two Surfaces*Total Vertical Force/Horizontal Forces to calculate the Sliding Factor, The Sliding Factor formula is defined as the factor of safety against sliding as the resisting forces (friction + passive) divided by the driving lateral force, and the minimum value should be 1.50. Where seismic loads are included, the minimum safety factor should be 1.10. Sliding Factor is denoted by S.F symbol.

How to calculate Sliding Factor using this online calculator? To use this online calculator for Sliding Factor, enter Coefficient of Friction between Two Surfaces (μ), Total Vertical Force (Σ_v) & Horizontal Forces (ΣH) and hit the calculate button. Here is how the Sliding Factor calculation can be explained with given input values -> 1.4 = 0.7*1400000/700000.
