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.
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.
