Behavior of high strength self compacted concrete deep beams with web openings [PDF]
Heliyon, 2019 Deep beams transfer loads through loading face to supports in an inclined direction and mostly fail in shear. These beams are with a small span-to-depth ratio. Openings are used to facilitate the passage of utility pipes and service ducts.

Refinement of Strut-and-Tie Model for Reinforced Concrete Deep Beams. [PDF]
PLoS ONE, 2015 Deep beams are commonly used in tall buildings, offshore structures, and foundations. According to many codes and standards, strut-and-tie model (STM) is recommended as a rational approach for deep beam analyses.
