Abstract

The use of steel as a framework for the roof of the warehouse building requires research on the efficiency of its volume according to the form of the frame designed by considering the strength and the economical of the building materials. In the implementation of this research the calculation of structural analysis using method of joint. The outline of the implementation step is to determine the profile data (quality and dimensions) and various controls on Gording, calculate the loading using SNI 1727-2013, calculate the structure analysis of each roof frame using Microsoft Excel, calculate the analysis of truss frame design (Tensile and press memberss), weld joint planning using SNI 1729-2015 and calculate the steel requirement volume ratio of the four types of roof truss structure. The result of the research shows that the volume of steel used in Type 1 roof truss construction is 0,2046 m3 with weight 1571,4287 kg; In Type 2 roof truss construction is 0,1862 m3 with weight 1461,5889 kg; In Type 3 roof truss construction is 0,1499 m3 with weight 1176,0578 kg; In Type 4 roof truss construction is 0,1488 m3 with weight 1167,4652 kg. Based on these results, the Type 4 is the most optimal type of roof truss construction, because the lowest volume and weight of steel was obtained. Keywords: Roof frame, SNI 1729-2015, steel, tensile member, press member

Abstract

ndonesia is an archipelagic country that passes seismic path, so that earthquakes often occur. Earth vibrations caused by an earthquake, can vibrate the structure on it and cause deformation that can damage the structural building. One effort to reduce the damage is by using seismic isolation system. This system will separate the structure of the horizontal components of ground movement by inserting the base isolator. This study was conducted to examine the effect of using base isolator (lead rubber bearing) when compared with the building without using base isolator on the medium soil and soft soil. Interstory drift is calculated using the response spectrum method by manual and Software SAP2000. Results of the analysis showed that the use of base isolator increase the natural period of the structure so that it can decrease the interstory drift in the building. The maximum interstory drift at fix base and base isolation is 4,3335 mm and 0,5741 mm on medium soil, 6,8606 mm and 0,9139 mm in soft soil, respectively. The reduction of interstory drift in both soil type reached 91%. Keywords: Interstory drift, seismic isolation, lead rubber bearing, response spectrum, SAP2000.

Abstract

Concrete is one of the construction materials that has the advantage of being able to withstand a high compressive strength but has a low tensile strength.To overcome the weaknesses that exist in the concrete, one of the efforts applied is to add fiber in the form of bendrat wire in the concrete in order to increase the tensile strength and flexural strength of concrete. The specimens of this research are concrete cylinder with diameter 15 cm and height 30 cm and concrete beam object with dimension of length, width and height 60 cm, 15 cm, and 15 cm respectively. Tests were performed at 28-days of concrete. While the addition of bendrat wire fiber is done based on the percentage of volume fraction (Vf) addition to the volume of concrete by 0%; 0,299%; 0,695%; and 0,990%. Each variation was made 9 test specimens consisting of 6 cylinders and 3 beams.The average compressive strength in high quality concrete without bendrat wire has the highest value of 50,0118 MPa. For the average compressive strength value at Vf 0.299%, 0.695%, and 0.990% were 42,2741 MPa, 41,8967 MPa and 39.6320 MParespectively. While for splitting strength and flexural strength in high quality concrete with volume fraction (Vf) 0,990% has the highest value with the splitting strength of an average of 4,6945 MPa and the average flexural strength of 7,9133 MPa Keyword : High quality concrete, bendrat wire fiber

Abstract

Bridges are constructions that connect people and land transportation that is blocked by obstacles. One of which is the type of cable stayed bridge.. This bridge structure consists of a combination of various structural components such as pylon, cable and deck. The deck is hung with a prestressed cable that is anchored to the pole. Gravitational and lateral forces acting on the bridge deck will be transferred to the ground via cables and pylon. The cable will receive tensile force and the pylon accepts the compressive force. This bridge planned 800 m long, 14 m wide traffic, 1.5 m sidewalk width, elongated girder type is tub girder, 300 mm plate thickness, cable arrangement is 2 fields and fan, and the cable used is VSL 7-wire strand. Girder quality of 290 MPa, concrete quality of 35 MPa, and welding quality of 490 MPa. Bridge model calculations are supported by SAP 2000 and Microsoft Excel programs. From the calculation results obtained the reinforcement design for the sidewalk using the main reinforcement D16-150 mm and reinforcement for D13-200 mm, reinforcement for vehicle floors both in the field and pedestal with the main reinforcement D22-100 mm and reinforcement for D16-100 mm. The dimensions of the girder used were flanges of 1 m x 0.05 m, web 1.3 m x 0.01 m and lower fluxes 4.2 m x 0.04 m. To get a more stable structure design, 3-dimensional analysis is needed. Keywords: Cable Stayed Bridge, Tub Girder, Girder

Abstract

The flate plate is a thick, evenly solid concrete plate that transfers the load directly to the support column without the aid of a beam or shear head or drop panel. This type of plate can be made quickly because of the formwork and simple reinforcement arrangement.  The flate plate is planned to be uniform with dimensions of 5000x4000 mm as many as 9 panels, plate thickness of 150 mm with 25 MPa concrete quality, quality of reinforcement 280 MPa and based on the provisions of SNI 1727; 2013 and SNI 2847; 2013. Flat plate analysis uses the equivalent frame design method, finite element method and SAP 2000 and Microsoft Excel programs. Based of the results of the analysis, the comparison value of moments between the portal method equivalent to SAP 2000 is equal to, whereas between finite element methods and SAP2000 is equal to. In the reinforcement plan, the number and diameter of the reinforcement were obtained in terms of the greatest moment value resulting from the analysis of the equivalent frame design method Keywords: Flat plate, Equivalent Frame Design Method, Finite Element Method

Abstract

The increasing development of high-rise building construction with unique design in Indonesia today can not be denied. The high-rise buildings must have earthquake resistance because of Indonesia is a country that has the risk of an earthquake. This requires a multi-storey structure designer to be able to design a multi-storey building structure with various conditions and configurations. Based on that problems, a building will be designed with unusual shape by inclining the entire main structural column with a slope angle is 80o. And as a comparison, another building will be designed which uses vertical column. The building plan will be located in Banjarmasin, South Kalimantan, Indonesia.The building plans with inclined and vertical column use reinforced concrete material with Ordinary Moment Resisting Frame (OMRF) as a structural strength system. This system is determined by the location of the building based on Indonesian Earthquake Map 2012. The result of the analysis and design is the building with inclined column has greater internal force compared to a building with vertical column and requires a reinforcement of 70.89% more than the building with vertical column.Keywords: earthquake, inclined column, building, concrete reinforcement, vertical column
