Span/Depth Ratios for Concrete Beams and Slabs
While the treatment of deflection in CP110 has been generally welcomed as an improvement on the rather rough-and-ready spaddepth rules in CP114, it is very cumbersome to apply in practice. The designer cannot check the spaddepth ratio until section design is almost complete and, if a problem arises, he/she has little guide as to what scope there is for solving it by redesigning with a reduced steel stress.
