154 Reinforced concrete beams-the ultimate limit state
design of flanged beams. Outline the procedure and derive the main design
formulae from first principles.
Ans. See Section 4.8.
4.15 Explain how Examples 4.6-8(b) and 4.6-9(b) should be modified if
the aim is to obtain actual resistance moments, for comparison with
laboratory experiments, for example.
Ans. To calculate ~he actual resistance moments, it is necessary to
remove the allowances for the partial safety factors Ym ( = 1.5 for
concrete and 1.15 for steel). This can be conveniently done by
writing 1.5/cu for feu and 1.15/y for /y in the equations in Examples
4.6-8(b) and 4.6-9(b).
