Question

4.2 Brief answer the following questions cribe the failure procedure of an under-reinforced concrete beam. Is it a preferred failure mode? Sketch the strain distribution of an RC beam section at tension control limit. If this section has an effective flexural depth of 21.5 inches, what's the dimension of the neutral axis depth? Describe in words, not with an equation, what is meant by the "balanced condition" in a a) Des b) c) concrete beam section. d) Assume o,, -0,003 according to ACI, prove mathematically the following equation. Note fy is used in psi unit. 87000 87000+ f, u+

Explanation / Answer

a)1.In under reinfored electio, percentagevof steel in less than pt for balanced section.

2.In this, the steel teachre its yield stress before the concrete. Hence, it's shows deflection well before failure unlike in over reinforced beam section.

3.yes it is a preffered method as the occupants of the building or structure gets enough time to evacuate the building to minimize losses.
