Reinforced Concrete Shear Walls

The chapter on seismic behavior and retrofit of existing reinforced concrete shear walls is still wide open. Researchers and engineers around the world are trying hard to develop new materials and innovative techniques for seismic upgrade of concrete structures. But why is this so important? Reinforced concrete shear walls have long been recognized as suitable Read more about Reinforced Concrete Shear Walls[…]

Durability or Strength?

Durability or Strength? Can’t we have both? Are they actually the same? These are sort of questions I hear in the engineering offices. Structural engineers are normally interested in mechanical properties of concrete materials. For example, from an structural design perspective, compressive strength of concrete, yield strength of steel reinforcement, depth of rebar, or modulus Read more about Durability or Strength?[…]
