The authors propose a method of unitizing steel members by using perforated I-beams as a substitute for steel bars in the upper slab of port road piers. In this study, concrete filling tests were conducted on a composite concrete structure using perforated I-beams to confirm the presence of filling defects just below the web of the I-beam. In addition, pull-out and bending load tests were conducted to confirm the adhesion performance to concrete and the bending load capacity of the composite structure. In the filling test, it was confirmed that concrete filled the area directly under the web by the perforated I-beam. The perforated I-beams were shown to have adhesion performance equivalent to that of I-beams with studs in the pull-out tests, and bending load tests showed that the perforated I-beams had bending load capacity and deformation performance equivalent to that of I-beams with studs.
