Abstract

United Tractors Company will build a sports center building consist of 3 floors using steel structures. Nowadays, limited land is one of the building development problems. The construction of multi-stored buildings is a solution to the limited land problem. The writer has analyzed beam design with a Wide Flange and Cellular system. Focused on the beam element with construction material in the form of steel with steel quality BJ-37, Fy 240 MPa, Fu 370 MPa. The strength and efficiency of the use of steel tonnage were also analyzed. E-Tabs software 2016 used to steel beam structure analysis. In this beam design planning refers to the steel structure planning following SNI 1729: 2015, SNI 1727: 2013, AISC 2010, ASCE 7-10, and also AISC Design Guide 31. The results of manual verification show that the cross-section of WF 400x200x8x13 and CB 250x125x5x8 with a span length of 6 meters is declared to be strong and safe because fill the strong requirements needs to be smaller than the strength of the plan. The efficiency of the use of Cellular Beam was compared to Wide Flange, the longer of Cellular Beam will increase steel tonnage reductions. The percentage reduction in steel weight will continue to increase when the length of steel usage also increases. This concludes that the use of steel length with steel weight reduction will move linearly. Where in this project with a steel beam length of 1439.27m reduction of steel tonnage was at 19.5%.

Abstract

Lime as a concrete mixture is done because lime contains elements of calcium oxide (CaO) which is the material for the manufacture of cement from 60-65% (Tjokrodimuljo, 2007). Glass waste comes from the waste glass industry has a silica content of 72.20% (Fikriansyah and Tanzil, 2013). The use of these two materials as a concrete mixture of substitution material is expected to reduce the pollution of the CO2 gas environment due to the burning of steam from the manufacture of cement and natural resources exploitation due to excessive aggregate mining. This research aims to determine the influence of sulphuric acid from 2% for strong concrete emphasis that contains glass in lieu of coarse aggregate and lime as a cement substitution. Penelitian ini menggunakan campuran lime dari 7% dan 10% dari berat semen, serta 5% dari limbah glass, dan 9% dari berat kerikil. Compressive strength testing is carried out on the 7th, 14th, 21th, and 28th days. Results of this study showed that the strong emphasis of concrete with a lime mixture of 10% + 5% Glass on 28 days obtained a strong press of 12.13 MPA higher than normal concrete ie 7.68 MPA on the 28th day.

Abstract

In the process of mobilizing coal on mine hauling road, which have to cross rivers, a bridge that is capable of carrying the traffic load from the mining truck is required. This study aims to plan a bridge structure with a composite box girder for coal mine trailer loads. In this study, the authors conducted a loading analysis based on SNI 1725 (2016) and planning the cross-sectional proportions based on the applicable provisions in (AASHTO, 2017). This research was carried out in several stages, starting from design of section proportions, flexure design, shear design, stiffener and shear connector. The results of this study show that the composite box girder can be applied at the research location and also the proportion of the cross-section that is able to withstand traffic loads working on the bridge structure with a nominal moment resistance value of 78856.13 kN.m which is greater than the ultimate moment due to loading that occurs with a value of 66912.64 kN.m.
