Abstract

The Cibitung - Cilincing toll road is faced with problems across many rivers and marshlands where the swampland is identified as clay. In building construction, the foundation is very important in bearing the burden of working on the upper construction. This Final Project contains the calculation of the carrying skin capacity and the end resistance of the pile using the Suyono method. S and Nakazawa (1990) based on N-SPT data and dynamic methods using the formula of Hiley (1930) based on the pile driving record data, then proceed to the calculation of the carrying capacity of the pile group, after that calculating the decrease of the pile using the Vesic method (1977). From the results of the analysis conducted by the author in calculating the bearing capacity to using N-SPT data and pile driving record data, the author gets that from the pile diameter of 50 cm, the carrying capacity of a single-pole is 66-ton, obtained using the method of Suyono S and Nakazawa, based on the formula of Hiley, it is obtained 139.34 tons, and settlement that occurred in the pile group foundation was an immediate settlement is 11.2 cm and a consolidation settlement is 6.2 cm.

Abstract

The foundation is a construction that continues the burden of the upper structure and passes it on to the soil below it. A bored pile foundation is now an option in working on structures in densely populated areas and tall buildings. The purpose of this study is to calculate and compare the carrying capacity of the bored pile foundation based on N-SPT data with the O 'Neil & Reese, and Reese & Wright methods, while the Loading test data with the interpretation of the Davisson method and the Mazurkiewicz method. The results of calculations based on N-SPT data, the average ultimate carrying capacity of the foundation with the O’neil & Reese method of 1211.61 tons, Reese & Wright of 1235.02 tons. While the Interpretation of Loading test method for Marzukiewicz is 1267.00 tons, Davisson is 850.40 tons, and the carrying capacity of PDA test results is 121.72 tons. From the calculation of the bearing capacity of the consecutive foundation of the smallest is the Davisson method, the O'neil & Reese method, the PDA test method, the Reese & Wright method, and finally the Mazurkiewicz method.

Abstract

The purpose of this study is to plan a construction stability of the upper and lower structures in the construction of the Depok - Antasari toll road section II, especially in the planning of a foundation. The foundation used in pier p1 is the foundation in the bored pile type. In planning the foundation, it is necessary to take into account the load force acting on the pier, the bearing capacity of the foundation piles, and the settlement. Analysis of bridge loading calculation (Badan Standarisasi Nasional, 2008) and (Badan Standarisasi Nasional, 2008) using a software program, namely SAP 2000 v.20. The purpose of this loading analysis is to find the value of the pier bearing reaction force to the working forces, both from the fixed load force and the environmental action load. In order for the purpose of this study to be achieved, literature studies from various sources both from the Indonesian National Standard and various other sources discuss the planning of foundation calculations, namely the AASHTO, Kullhawy, Vesic and Reese Wright methods. The results of this study explain that it must be paid attention to planning a foundation that meets the parameters and structures that are safe against earthquakes and other loads, it is also necessary to take into account the momentary reaction force, bearing capacity of the pile and land subsidence according to national standards.

Abstract

In the process of planning earthquake-resistant building structures, steel structures are still an option. This is because steel material has relatively high load resistance and elastic properties of steel which contribute to better ductility and energy dissipation than concrete. Eccentric Brace Frame System (SRBE) is a lateral load bearing system that has good strength, stiffness and ductility. In this study, the SRBE Short Link Multistory X-bracing type structure with variable link length and L / H ratio was evaluated using pushover analysis to determine the structure's behavior and performance in terms of stiffness, strength and ductility of the structure. The analysis was conducted on 9 10-story building models with different link lengths and L / H ratio. From the results of the comparative analysis of each structural model, it is found that the C2 model with a link length of 900 mm and an L / H ratio of 1.5 has a stiffer structure. Model C3 with a link length of 900 mm and a ratio of L / H = 1.75 has a greater strength to withstand earthquake loads. The use of a link length of 300 mm and an L / H ratio = 1.5 results in an increasingly ductile structure. The results of the structural performance are at the Immidiate Occupancy level, but there are several models with one of the X or Y load directions that have a Life Safety structural performance level. The use of a link length of 300 mm and an L / H ratio = 1.5 results in an increasingly ductile structure. The results of the structural performance are at the Immidiate Occupancy level, but there are several models with one of the X or Y load directions that have a Life Safety structural performance level.

Abstract

DKI Jakarta has a population density of 19,516 people / square km. Government of Jakarta in the PERDA DKI Jakarta No. 7-2010 CHAPTER 5 Article 42 Paragraph 1 states that "every building must provide parking space". To overcome this, semi-basement will be an option to make a parking space that does not require too much excavation costs. This analysis will compare two types of retaining walls, cantilever retaining walls and conventional retaining walls using the Rankine method for static conditions and the Mononobe-Okabe method for dynamic conditions. This analysis results in the conclusion that for a depth of 2.00m, conventional walls are found to be more efficient in terms of costs with a difference of up to Rp. 178,700 / m’. For soil with a depth of 1.75m, cost efficiency depends on soil cohesion. For the higher soil cohesion, the cost of making cantilever walls is more efficient, reaching Rp. 130,600 / m '. For soil with a depth of 1.50m, with higher cohesion, the cantilevered wall will be more cost-efficient than conventional wall making, reaching Rp. 232,400 / m’.

Abstract

The construction of a foundation is very large function in a construction. In general the foundation is defined as an underground building that passes on the load derived from the weight of the building itself and the outer load that works on the building to the surrounding land. The foundation of the stake is a relatively long and slim rod that is used to channel the foundation load through the soil layer with a low support capacity of hard soil layer that has a high carrying capacity that is relatively deep compared to the shallow foundation. The carrying capacity of the stake is derived from the end bearing capacity obtained from the pressure of the end of the pole and the friction bearing capacity obtained from the carrying capacity of the friction or adhesion force between the stake and the surrounding soil. This research uses an analytical research method in which in the calculation of the planning of the foundation of the stake using the calculation of the capacity of carrying capacity with the method of bagemann and mayerhoff. From the calculation of vertical style carrying capacity based on sondir data using bagemann method at the first stake point of 1059.50 kN and at the second point of 1015.95 kN, and the result of SPT data using mayerhoff method at the first stake point of 663.88 kN and at the second point of 498.76 kN. Qultimate single pole horizontal carrying capacity calculation of 216 kN, Single Qizin amounted to 72 kN, Group of 228 kN.The result of the calculation of vertical carrying capacity of the group stake is 734.1732 kN.The result of the calculation of tuggal pole reduction is 11.62 mm, The stake group is 10.77 mm, so the calculation result for the drop of a single pole is smaller than the permit drop which is smaller than 100mm.
