- used The castellated beam in structures is generally for piping installation and to substitute the conventional methods such as hanging the pipe or duct to the beam. Making beams with holes in their body is not going to drastically reduce the modulus. However, when the hole is too large, the shear capacity in the castellated beam will also decrease. One of the methods used to increase the shear capacity and moment capacity due to the hole in the castellated beam is by adding wire rope as the longitudinal reinforcement, stirrups reinforcement and mortar composite. -square hole opening with The objective of this study was to observe the flexural behavior of the castellated beam in four wire rope, stirrups reinforcement and mortar composite. The steel beam used in this study was the IWF profile with 150x75x7x5 mm dimension. After changed into castellated beam, the dimension became 275x75x7x5 mm. The test was carried out for two beams: one Castellated beam (BC) without composite and one composite beam (BK) with wire rope, stirrups reinforcement and mortar composite. The Wire Rope used was Independent Wire Rope Core (IWRC) in 16 mm diameter. The mortar composite applied the cement-sand ratio of 1:1.5 with water cement ratio of 0.4 and viscocrete 0.7 %. Two points static loading test method was employed. , Results of the study showed that based on the experimental test the maximum load capacity capable to bear by the castellated beam was 24.6 kN. By adding wire rope, stirrups reinforcement and mortar composite to the castellated beam with foursquare hole opening, the maximum load capacity increased in 166 kN. The deflection resulted from the experimental test for castellated beam without composite was 116.65 mm. After the the moment capacity of the castellated beam in the composite have increased, the deflection decreased to 62.34 mm. However, the increase was obtained after the development and spreading of high cracks. The stress occurred in the wire rope, based on the Response-2000 program and theoretical analysis, indicated that it has not reached 50% of the ultimate stress.
