cables. If the openings interrupt the load path joining the
loading and reaction point, it is obvious that the simple load
path changes to a more complex one, and the shear capacity
will be reduced. In spite of signi cant effects of the openings on
the structural behavior of deep beams, there is no clear design
guidance for deep beams with openings. In addition, most of its
tests have focused on solid deep beams except for only very few
research papers on deep beams to have compressive strengths in
the range of 18–30 MPa including the effects of openings (2,7,8,10)
