Abstract EN
Service runs considered as a major nerve of any building.
Thus, beam with longitudinal and transverse opening (BLTO) was creative solution for the purpose of serve those runs with other benefits, especially when utilized high strength self-compacting concrete (HS-SCC).
This study examined the behavior of eight reinforced concrete (RC) beams.
These beams were involved into two groups.
All beams had identical in dimensions, reinforcement, concrete type, and hole dimensions.
The evaluation used to elect the optimum hollow core section, and position effect of web openings with fixed hollow core section.
Due to recorded load capacity, a reduction was produced by hollow core position at mid and bottom section by about (2% -14% ), respectively, with comparing by solid section.
Therefore, the optimum hollow core section was when it locate in mid beam section which used to unify BLTO sections.
BLTO types indicated different loading data according to web opening position.
The decrement of opening provision was about (20.4% ) by compared with hollow beam (without transverse opening) and about (22% ) by compared with the solid beam.
The optimum BLTO was when the web opening located in mid-shear zone, while the critical one recorded in web opening position in mid-span and near supports in same BLTO.
The registered failure mode of all beams was contained two main types, suddenly flexural failure in compressive zone by concrete cover crushing and flexural-shear failure.
