(9) The vibrated concrete, the sdr -entrained concrete, and the comparatively recent advancements in prestressed concrete and its prestressing techniques, have given an impetus to the prestressed concrete tie business. The prestressed ties are of stiff beam type. These are made in one piece, moreover they look like the wooden ties.

Spring Constant

Spring Constant (also called stiffness) = Area x Elastic Modulus / Total Length . This holds for any axially loaded beam of constant cross section - if the beam is circular and hollow, just work out the area and put it into the formula.

Prestressed Concrete

Stress Anchors Stress Anchors (also commonly known as Live Anchors) is the most widely used form of anchors in prestressed concrete works. It consists of Anchor, Casting, Wedge and Bursting Reinforcement. It is most commonly found in bonded post tensioning using PC strand as tendons in prestressed concrete structure and rock/soil anchoring structure.
