Nondestructive evaluation for hybrid-composite girder bridges
… fiber reinforced polymer (FRP) shell enclosing a concrete arch tied with steel prestressing strands. The form for the concrete arch is shaped as a void within the composite shell. Concrete can be placed either before or after the beams have been erected, reducing crane requirements and providing a …

Structural Behaviour of Self Consolidating Steel Fiber Reinforced Concrete Beams
… of moment and shear force, a reinforced concrete (RC) beam with either little or no transverse reinforcement can fail in shear before reaching its full flexural strength. This type of failure is sudden in nature and usually disastrous because it does not give sufficient warning prior to …

Early age creep and shrinkage of emerging concrete materials
Concrete pavements and structures are especially vulnerable to cracking at early age. The volumetric instability of concrete at early age is a frequent cause of cracking. The primary components of volume change are external drying shrinkage, autogenous shrinkage, and thermal dilation. When concrete …
