Examples of continuous deep beams
There is no universally accepted definition of deep beam. In general,
European deep beams are approximately twice as deep as North American
deep beams. For example, CEB-FIP (1970) suggests that simply supported
beams of span/depth ratio
L/D
(where
L
is the beam span in m, the smaller
of the centre to centre span, or 1.15 times the clear span;
D
is overall beam
depth in m) less than 2 and continuous beams of
L/D
ratio less than 2.5 be
designed as deep beams. ACI (1986) suggests that beams with clear with
