Abstract

Steel construction work generally requires a maximum power that can be retained by a cross-section of the burden, so for that we need a large enough cross-section to carry the load. In an attempt to overcome this problem, created a new profile as needed, so that the use of a cross-section Walled Beams Plates Plates Full or often called Girder (Girder Plate). Fully walled plate girder is a beam with a high cross-section, so it is probably influenced by the folding wings on plate element or the element plates bend the body, so that the necessary calculations to solve the folding and buckling. To overcome this happens folding or bending, buckling calculations required lokak (local buckling) and if it is necessary, then the component mounted stiffeners (stiffener), Bearing stiffener, Intermediate stiffener, and Longitudinal stiffener. To meet the needs of the beams to support the existing load, so he found a full-walled beam size plate (Plate Girder) d = 1,400 mm high, with a weight plate size 15 mm x 1350 mm, and the wing plate size 25 mm x 500 mm of steel fy = 240 MPa. Beam stiffeners fitted pedestal (Bearing stiffener), stiffeners between (Intermediate stiffener) and longitudinal stiffeners (stiffener Longotudinal).Keywords: girder plate, local buckling, stiffener

Abstract

Concrete is one of the building materials are very useful in the construction, where concrete is a mixture ofPortland cement (PC) or other hydraulic cement composition includes a mixture determined between fineaggregate, coarse aggregate and water, with or without the use of additional materials. The study was conductedto determine the compressive strength of concrete and other specifications that concrete is achieved by theaddition of Conplast SP 337. That is done using a cube-shaped test specimens measuring 15 cm x 15 cm x 15 cmwith 5 (five) variation of mixture B1, B2, B3, B4, and B5, each four (4) specimens. for each test age of 3 days, theage of 7 days, 14 days, 21 days and 28 days. From the research, it was found that the compressive strength ofconcrete with each stir the mixture obtained 1.2: 2: 3 (B5) compressive strength greater of 4.5% of thecompressive strength of normal concrete specimen (B1). And the compressive strength of the mortar 1: 2,5: 3 withthe addition of SP 337 (B5) is lower than the compressive strength of normal concrete specimen (B1) amounted to23.71%.
