Abstract

Cold formed steel is a material is often used for construction roofs. The advantages of cold formed steel and its large tensile resistance have attracted interest to developing research make cold formed steel as a beams. Galvalum is a type of cold formed steel. Galvalum consists of galvanis material and aluminium. However, cold formed steel has a weakness against compressive forces so filler materials is a needed. The filler used in this research is a mortar with variation the ratio of cement to sand 1: 1, 1: 2, 1: 3, 1: 4. Another factor that increases the bending test is the addition of reinforcement bar to the beam which is intended as a beam stiffener. In this research used reinforcement bar formed by the cold formed steel profile itself with variations of reinforcement bar of 2, 3, 4, and 5. From the results of the mortar compressive strength test, the greatest compressive strength was obtained by 1: 1 mortar variation. The addition of sand to the mortar caused the compressive strength of the mortar to decrease. From the results of bending test, it was found that the smallest deflection value with the maximum load resistance, and the maximum stress and strain were obtained by the cold formed steel beam with the most reinforecement bar and 1: 1 mortar variation. From the research results, cold formed steel beams can be used as non-structural beams. For further research, further development is needed and is expected to be able to produce a greater load so that cold formed steel beams can be used as structural beams.
