Analysis
As mentioned earlier the conventional deep beams method can be
conservatively used for the design and detailing of flanged deep beams. A
number of commonly used methods are available for the designing of
reinforced concrete deep beams. Most of the methods are developed for
directly loaded deep beams, but these also can be applied to indirectly
loaded deep beams provided properly designed suspension or hanger
reinforcements are provided and well anchored in the top compression zone.
Paul (1978) showed that indirectly loaded deep beams with hanger
reinforcement attained strength equivalent to those of directly loaded beams
if well anchored hanger reinforcement was provided. The commonly used
procedures for deep beam analysis are:
i) ACI Building Code; ii) CEB-FIP Model Code (See Chapter 1, Section 1.5 for
an account); iii) CIRIA Guide 2; iv) the method proposed by Taner
et al.;
v) the
method proposed by Regan and Hamadi; vi) the method proposed by Subedi.
