Principles of Reinforced and Prestressed Concrete

PROBLEM

A simply supported rectangular beam of length ? has a width of ? and an effective depth of ?. Compression steel bars are placed at a distance ?′ from the extreme concrete compressive fiber. The beam supports service dead loads of ?? and ??, respectively. Use ??′ = 28 ??? and ?? = 420 ???. For the reinforcements, use 4 25 ?? tension steel bars and 4 12 ?? compression steel bars.

Given:

b = 197.5 mm

d=317.5mm

d’=77.5mm

L= 2.7 m

Wd = 13.75 kN/m

Wd = 17.75 kN/m
