Abstract

Steel is one of the many alternative building materials used in construction, because of the uniformity of the material and its properties that can be expected is quite appropriate, dimensional stability, ease of manufacture and faster implementation. During this steel profiles are widely used in building construction for the columns, beams and girder bridge is the profile of WF (wide flange) are heavy, this study attempted to use a lightweight steel C profiles for the column. This study uses a coupled double C profile as a given column with steel stiffener plates laterally. Long double C profile steel column is 1000 mm as a short column and a column length of 3500 mm. Dimensional profile of C used the width (b) 35.8 mm, height (h) 68.6 mm, and thickness (t) 1.9 mm. Specimens in the form of double C profile steel columns by 8 pieces with a variety of different stiffeners is 100 mm, 150 mm, and 200 mm and 250 mm. Column C double profile is reviewed maximum strength to withstand the load centric. The results obtained, the maximum load on a short column averaged 5399.46 kg, while the maximum load length of column averaged 3199.68 kg. The maximum deflection occurs is short columns: column with lateral bracing distance 250 mm deflection 6.12 mm, column with stiffener lateral distance of 100 mm, 150 mm and 200 mm, respectively for the deflection of 2.86 mm, 2.63 mm, and 2.36 mm. The maximum deflection in long columns: column with 250 mm lateral bracing distance is equal to 33.56 mm, column with stiffener lateral distance of 100 mm, 150 mm and 200 mm, respectively for 26.8 mm, 23.02 mm, and 21.61 mm.
