Bamboo Reinforced Concrete a Critical Review

87 88 2.1 Strength 89 In conventional steel-reinforced concrete design, members are designed to be 'under reinforced' 90 such that the reinforcing steel yields prior to concrete crushing. This ensures a ductile member 91 response by engaging the inherent ductility of the steel. This behaviour also results in an inherent 92 overstrength or reserve capacity above the design requirement by ...

Reinforced Concrete Theoretical Description

The reinforced concrete material model is treated as statistically homogeneous with different tensile and compressive behaviors. It follows a "smeared" crack model where cracking and crushing are simulated via degeneration of the elasticity at integration points instead of tracking individual macroscopic cracks.
