The effect of recycled concrete aggregate properties on
Recycled concrete aggregate (RCA), produced by crushing concrete from demolished concrete structures is a potential solution to this problem. By reusing demolished concrete structures, it can potentially reduce coarse aggregate costs, resulting in reduced CO 2 emissions associated with aggregate transportation, and reduced construction debris being placed in landfills.

Guide Examples for Design of Concrete Reinforced with FRP Bars
For concrete crushing, the Whitney rectangular stress block is used to approximate the concrete stress distribution at ultimate strength conditions. For FRP reinforcement, the linear-to-failure stress-strain relationship must be used. If the FRP reinforcement ruptures, sudden and catastrophic failure can occur. Therefore, concrete crushing has

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.
