reinforced concrete structures is nonlinear; in fact, considerable redistribution of moments may occur due to cracking of structural members and the plastic behavior of materials." The amount of redistribution that can occur in an indeterminate reinforced concrete structure depends on both material and geometric factors.

material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete. Aggregate properties significantly affect the workability of plastic concrete and also the durability, strength, thermal properties, and density of hardened concrete.

where. f y = the yield stress of the steel reinforcement (we will use 60 ksi in all examples). f c ' = the compressive cylinder strength of the concrete (ksi). ρ = the steel ratio, A s /(bd) For given values of f y and f c ', the relationship between R and ρ can be computed from Equation 5.13. Appendix Table A-5.9 gives typical values of R and ρ for f y = 60 ksi, and …

Explain why steel and concrete are used in conjunction in RC. In Reinforced Concrete (RC), steel is used to strengthen the section against tension in particular (also to resist …

The use of small diameter whole-culm (bars) and/or split bamboo (a.k.a. splints or round strips) has often been proposed as an alternative to relatively expensive reinforcing steel in reinforced concrete. The motivation for such replacement is typically cost—bamboo is readily available in many tropical and sub-tropical locations, whereas …
