It is observed that in smaller drainage areas, more pressure differential is required to fail tarmat, tarmat having higher yield strength, requires more pressure differential until failure and tarmat with smaller Poisson's ratios, requires more pressure differential until the failure point.
The limits on yield strength are required to ensure adequate ductility of a section and are related to the prescribed limit on concrete compressive strain of 0.003.
For the Bingham rheology the model requires the following inputs: viscosity, yield strength, gravity acceleration, and unit weight of the flow.
A 7.5-mm thick A36 steel with minimum yield strength of 400 MPa was required for the thick steel repair technique.
For a tarmat with a certain thickness, lateral dimensions, Young's modulus of elasticity, Poisson's ratio and yield strength, more pressure differential is required to observe failure in the case of non-uniform loading.
Inspection of Fig. 4 reveals that as the Young's modulus of elasticity and yield strength becomes larger, the pressure differential required for the tarmat to fail increases while its deformation is expected to slightly decrease.
As yield strength of tarmat increases, pressure differential that is required to fail the tarmat increases.
As Young's modulus of elasticity and yield strength of tarmat increase, pressure differential that is required to fail tarmat increases, and magnitude of deformation that occurs until failure of tarmat decreases.
This model requires to input the parameters for the Young's modulus E, yield strength σ y, and strain hardening parameter μ.
It is expected, since the tensile force in confinement steel is directly proportional to the amount and the yield strength of steel, a higher strength concrete would require higher confinement pressure.
