To accurately model the nonlinear RC behavior involving concrete cracking in tension and crushing in compression, practitioners make different choices regarding the critical modeling issues, e.g., defining the concrete constitutive relations, assigning the bond between the concrete and the steel reinforcement, and solving problems related to convergence difficulties and mesh sensitivities.

Concrete crushing after yielding of steel reinforcement represents an under-reinforced member, which is typical of current reinforced concrete design standards. This failure mode ensures that a high level of member ductility is maintained prior to failure, thus providing ample warning before collapse.

Concrete modelling to predict crushing in compression. I''ve found a method to model reinforced concrete using a combination of Calculix and Mohr Coulomb stress. Three types of analysis are performed: 1) An elastic analysis using Calculix (only utilising the elastic parameters for concrete); 2) A post processing step to analyse the required

Hadi et al. reported similar observations with GFRP-reinforced solid concrete columns with reduced spacing between the lateral reinforcement. A drop in the axial-load resistance was observed due to concrete cover crushing . Columns HNC-0-00, HGC-4-16, HGC-6-16, and HGC-8-16 showed 5.0%, 8.1%, 3.3%, and 2.5% drops in P 1, respectively.

Fiber-reinforced concrete prevents, or at least heavily reduces, early cracking right from start. Durability and strength. The addition of fiber increases the overall durability of the concrete, can help lower corrosion levels, cavitation damage, and has a higher level of tensile strength when compared to concrete that is not reinforced.

908. Recycled concrete requires the crushing and removal of reinforced steel during processing. Malcolm Davy discusses how magnetic separators can assist in the process. Today, the recycling of materials is important to preserve our reserves of raw materials. We see it everyday in liquids, glass, metals, rubber, plastics and even concrete.
