Abstract

For several cases of delivery of beam is location for install such as location for manoeuvre. Another case is available of material for mixing concrete as fine aggregate and coarse aggregate. For that cases research about segmental girder was needed and was done with lightweight concrete as material for reduce weight of its beam and called precast hybrid concrete beam. Question of this research is how about strength of flexural hybrid beam if any load were applied and how about deflection occur. Aim of this research was investigated of strength of flexural hybrid beam and deflection occur if compared with conventional beam. This research consist of two types of precast beam that was hybrid beam (BU227 and BU 228) and conventional beam (BU226). Result of precast hybrid concrete beam BU227 and BU228 and conventional beam BU226 were strength of flexural beam at ultimate and deflection of beam at ultimate. For strength of flexural conventional beam BU 226 at ultimate was achieved 10,48 T at deflection 29,6 mm. For strength of flexural precast beam BU 227 at ultimate was achieved 10,15 T at deflection 23,43 mm and for strength of flexural precast beam BU 228 at ultimate was achieved 10,33 T at deflection 27,19 mm. Average compressive strength of lightweight concrete was achieved 49,58 kg/cm2.Conclusion of this research is both of precast hybrid beam are having good performance and can be applied at location with difficult to manouevre and difficult for availability of materials for mixing concrete.
