The maximum shear stress (τc,max) in concrete of a reinforced cement concrete beam depends on grade; for example, for M20, it is 2.8 N/mm². (Refer Table 20, IS 456:2000)

What is Negative skin friction and how it works.

-
Image
  Negative skin friction (NSF) refers to the phenomenon that occurs when the friction between a soil or rock surface and a pile or foundation element creates an opposite force, pulling the foundation down into the ground rather than resisting its movement. This is commonly observed in piles or deep foundations that are embedded into soft soils, especially in areas where the soil undergoes consolidation or settlement. Here’s how it works: 1.      Soil Consolidation or Settlement : In soft, compressible soils, like clay or silt, when the soil undergoes settlement (due to load or natural compaction), it can cause downward movement of the soil around a pile or foundation. 2.      Friction Development : As the surrounding soil consolidates or moves downward, the friction (skin friction) between the pile surface and the soil increases. Normally, this friction resists the movement of the pile, providing support. 3.      ...

  what is torque and torsion? what is the difference between torque and torsion? The terms torque and torsion are related to rotational forces, but they describe different concepts: Torque : Torque refers to a force that causes an object to rotate around an axis or pivot point. It is the measure of the rotational force applied to an object. The formula for torque is: τ=F×r×sin⁡(θ)\tau = F \times r \times \sin(\theta)τ=F×r×sin(θ) where τ\tauτ is the torque, FFF is the force, rrr is the distance from the pivot point, and θ\thetaθ is the angle between the force vector and the lever arm. Torque is typically used in situations where a force is applied at a distance from a center of rotation (like turning a doorknob or the engine in a car). Torsion : Torsion refers to the twisting of an object due to an applied torque. It describes the stress and strain experienced by a material when it is subjected to ro...

Difference between pre tensioning and post tensioning

-
Image
v   Pre Tensioning Vs Post Tensioning:-Pre-tensioning and post-tensioning are both methods of pre stressing concrete, which involves reinforcing concrete with steel tendons .   ü Pre tensioning vs post tensioning When tendons are tensioned before concretes    are poured is called pre tensioning. When tendons are tensioned after concretes are hardened is called post tensioning. It is good for precast construction . It is good for long span and high structural efficiency. Steel is mostly stay horizontal. Steel wires can be placed any desired profile. §   Work Function:- 1)      In pre tensioning steel tendons are stressed before concrete is poured around them.   2)      In post tensioning the steel tendons are inserted in void in cured concrete using jacks.the jacks are replaced with permanent anchorages .   o    Benef...
