Abstract

AbstractPlate girder is a flexible structural component that composed from several plate elements. Basically, plate girder is a beam with a large cross-sectional size and a long span. Plate girder is an alternative if the largest hot rolled steel profile is insufficient to carry the working load due to its long span.This research will plan the main structure, that is girder plate for a multi-storey building with a hanging system (suspension building), and also plan the complementary components. Generally, the implementation steps of the process are collecting planning data, calculating loading, calculating the forces those worked on the structure using SAP2000, after that, designing the girder plate profile, and other components such as joint design and stiffener design, so that safe structural details are obtained.In the design that has been done, the column dimensions are obtained (h = 1500, bf = 500, tw = 8, tf = 30) mm, beam (h = 1500, bf = 450, tw = 8, tf = 30) mm, transverse stiffener ( bp = 120, tp = 8, h = 1440) mm, column-beam joints (Db = 24mm, n1 = 36 bh, n2 = 78 bh), beam-beam joints (Db = 24mm, n1 = 32 bh, n2 = 70 bh), splice joints (Db = 24mm, n1 = 26 bh, n2 = 16 bh), and base plate connections (Db = 24mm, n1 = 10 bh). Based on the design, the profile and components are quite safe to use.Keywords : Girder Plate Beam, Steel Structure, Building Structure Design, Suspension Building.

Abstract

The subgrade is a very important role in road construction because it is the beginning of determining the quality and capacity of the soil bearing capacity. One way to strengthen the soil is by soil compaction because it can reduce the amount of unwanted soil subsidence and to rearrange the soil grain structure, so that it becomes denser so that the soil will be denser.This study used grained soil, the type of silty sand from Muara Dua Village, Ulu Belu District, Tanggamus Regency, Lampung Province. The method used is standard compaction and laboratory CBR to determine the impact of the pressure value using a modified press device. The burden used in this research is 3 MPa, 6 MPa, 9 MPa, 12 MPa, and 15 MPa.In the modified press tool test, the values obtained were 12.1 MPa and Laboratory CBR for 3 MPa pressure was 2.7%, 6 MPa pressure was 3%, 9 MPa pressure was 7.8%, 12 MPa pressure was 12.3%, and pressure 15 Mpa of 15.9%. So it can be concluded from the impact of the pressure value using a modified press tool is that the greater the pressure value, the CBR value will increase.Keywords: Standar Proctor, CBR Laboratory, Modification Press Tool.

Abstract

The construction of the Trans Sumatra Toll Road provides convenience for the public. The distance from the Natar Toll Gate to the intersection of the Lintas Sumatera Road, which is 2,5 km will interfere with toll performance at the peak of holidays if it is not properly regulated. Therefore, it is necessary to do reaserch to determine the performance of toll roads at the Exit of Natar Toll, to know the performance of roads outside the city on Jalan Branti Raya and to find out the performance of signalized intersections at the Natar Toll Exit Intersection. This reaserch use the 2014 Indonesian Road Capacity Guidelines (PKJI) method. The results show that the performance of the toll road at the Natar Toll Exit was still adequate with degree of saturation with direction 1 is 0,09 and direction 2 is 0,13. The performance of roads outside the city on Jalan Branti Raya  was still adequate with degree of saturation with direction 1 is 0,47 and direction 2 is 0,43. The performance of the signalized intersection at the Natar Toll Exit Intersection is almost saturated with the degree of saturation the south approach is 0.67; the east approach is 0.08 and the north approach is 0.82. The queue for the south approach is 30 meters; the east approach is 2 meters and the north approach is 84 meters. The average delay of the intersection is 25 seconds /skr. To improve the performance of the Natar Toll Exit Intersection, it is necessary to rearrange the green time at this intersection.

Abstract

An urban area that has a function as a center of activity in an area certainly affects the high levelof community activity and indirectly causes a high number of movement of people, vehicles andgoods in urban areas.The ability to accommodate traffic flows depends on the physical conditionof a road, both in quality and quantity as well as on the operational characteristics of thetraffic.The purpose of this study is to analyze road characteristics and to determine therelationship between volume, speed and density on the Zainal Abidin Pagar Alam road and theImam Bonjol road in Bandar Lampung. This study uses the Greenshield and Greenberg modelsas a method. This method results that the relationship between velocity and density is linear sothat we can see how the pattern of the relationship between velocity, density and volume is. Theresults of this study obtained the free flow speed for Jalan ZA Pagar Alam for 55 km / hour andfor Jalan Imam Bonjol is 38 km / hour. The actual speed on Jalan ZA Pagar Alam is 28km / hourand on Jalan Imam Bonjol is 30km / hour. Meanwhile, the congestion density found on the ZAPagar Alam road is 931 cur / hour and on Jalan Imam Bonjol is 979 cur / hour. The mostoptimum model is in the Greenberg model for Jalan ZA Pagar Alam because the Greenbergmodel has a determination coefficient value (R2) which is closer to the highest accuracy of 0.98%and the Greenshield model on Jalan Imam Bonjol is because it has a determination coefficientvalue ( R2) which is closer to the highest accuracy of 0.96%.

Abstract

Dams have various functions and benefits, such as irrigation sources, flood control, power generation, tourism etc. The problem that is concerned about the dams that have been built in developing countries such as Indonesia is in particular the problem of sedimentation in the reservoir. Way Sekampung is one of the rivers which is the source of water in the Batutegi reservoir. Way Sekampung has a large discharge. However, Way Sekampung which has a fairly heavy flow also carries sediment which must be taken into account so as not to disturb the stability of the existing river. Therefore, a research was conducted on sediment discharge and transport in the Way Sekampung river. The discharge analysis used field current meter data and sediment analysis used field sediment samples. Comparative data is calculated using the HEC-RAS application so that there are variations in the discharge in the calculation. The Way Sekampung River produces a sediment discharge of 0.0814 m3 / s at Cross Section 1 and 0.0999 m3 / s in Cross Section 2 using the Meyer Peter and Muller method. Compared with empirical calculations, the sediment rate value is 0.0822 m3 / s in Cross Section 1 and 0.0798 m3 / s in Cross Section 2 using HEC-RAS discharge modeling and Einstein method.

Abstract

The importance of soil as construction material needs to be considered carefully. With various soil conditions, a physical test is required to discover the characteristics of the soil and California Bearing Ratio (CBR) test in a laboratory to determine the bearing capacity of the basic land (subgrade). This research was conducted to assess the suitability of the CBR test value with two different compaction tools. The results of this study showed that the soils were classified into A-6 clay soil type. On the modified proctor compaction test, the maximum weight volume (γdmaks) was 1,70 gr/cm3, while the compaction with modified press tool obtained 1,75 gr/cm3. Based on the results of the values obtained from CBR standard test is 11,5% and 1,32% for the soaked sample .While the CBR value without immersion with modified press tool are 7,7% for 3 MPa, 16,2% for 6 MPa, 19,5% for 9 MPa, 20,5% for 12 Mpa. For the soaked samples are 1,53% for 3 Mpa, 2,7% for 6 Mpa, 3,56% for 9 Mpa, and 4,33% for 12 Mpa. In conclusion, the CBR value escalation is higher when using the modified pressure tool compared with the CBR standard method.
