The solution of deep-beam type problem using
plasticity concepts
was
reported by Nielsen (1971) and Braestrup and Nielsen (1983); shear
strength prediction by the plastic method is covered in Chapter 8 of this
topic. Kong and Robins (1971) reported that
inclined web reinforcement
was highly effective for deep beams; this was confirmed by Kong and
Singh (1972) and Kong
et al.
(1972a) who also proposed a method for
comparing quantitatively the effects of different types of web
reinforcement (Kong
et al.,
1972b). Kong and Sharp (1973) reported on
the strength and failure modes of deep beams with
web openings;
the
proposed formula for predicting the ultimate load was subsequently
refined (Kong and Sharp, 1977; Kong
et al.,
1978) and adopted by the
Reinforced Concrete Designer's Handbook
(Reynolds and Steedman, 1981
and 1988). The topic has been followed up by Ray (1980) and others and
is the subject of Chapter 3. Robins and Kong (1973) used
the finite
element method
to predict the ultimate loads and crack patterns of deep
beams; Taner
et al.
(1977) reported that the finite element method gave
good results when applied to flanged deep beams. The finite element
method is now covered in Chapter 9 and
flanged deep beams
in Chapter 5.
Serviceability and failure under
repeated loading
was studied by Kong and
Singh (1974). Garcia (1982) was among the first to carry out
buckling tests
on a substantial series of slender concrete deep beams; these and the
subsequent tests by Kong
et al.
(1986) and others are discussed in Chapter
10. The effects of
top and bottom loadings,
the subject of Chapter 6, was
