In this study, settlement analysis of pile groups by hand calculation methods were investigated. Settlement ratio, equivalent pier, and equivalent raft methods were studied. Variations in some of the calculation methods were noted, and some suggestions were given. More than thirty piled raft foundation case histories whose foundation and soil properties known have been found. The settlement of piled foundation in each case was solved by these methods. Results obtained from the calculations following different methods were presented for each case in the form of tables and graphs. Measured and calculated values were compared by making use of graphs and tables. Effect of type of piles was shown. It was tried to find out that which method is suitable under different conditions. In conclusion, suggestions for methods and calculation procedures were given.

Kazıklı radye temellerin etkin tasarımı Ergün, Ufuk M.; Türkmen, Kürşat H.(2005) In this study, the load bearing behavior of piled raft foundations is investigated performing laboratory and field tests. Test setups were mainly concerned with the load sharing mechanism of piled raft foundations. Load-settlement characteristics of the piled raft foundations were also investigated. In the field load test, the model piled raft foundation was loaded in vertical and lateral directions. 4 bored piles with a diameter of 32 cm and length of 5 m are supporting a reinforced concrete raft with plan...
Distribution of bending moments in laterally loaded passive pile groups a model study Öztürk, Şevki; Ergun, Mehmet Ufuk; Department of Civil Engineering (2009) In this study, bending moment distributions developed in laterally loaded passive pile and passive pile groups in cohesionless soil were investigated in laboratory conditions through model pile experiments. Different from the active pile loading, the lateral load was given directly to the piles using a movable large direct shear box. In these experiments strain gauges fastened to the piles and a computer based data reading system were used. The strain values were measured at five levels on the piles. The be...
Estimation of Hardgrove grindability index of Turkish coals by neural networks Ozbayoglu, Gulhan; ÖZBAYOĞLU, AHMET MURAT; Ozbayoglu, M. Evren (Elsevier BV, 2008-01-31) In this research, different techniques for the estimation of coal HGI values are studied. Data from 163 sub-bituminous coals from Turkey are used by featuring I I coal parameters, which include proximate analysis, group maceral analysis and rank. Nonlinear regression and neural network techniques are used for predicting the HGI values for the specified coal parameters. Results indicate that a hybrid network which is a combination of 4 separate neural networks gave the most accurate HGI prediction and all of...
A SIMPLIFIED APPROACH TO THE SETTLEMENT ESTIMATION OF PILED RAFTS Kalpakci, Volkan; Özkan, M. Yener (2012-01-01) In this study, a simplified approach to the settlement estimation of piled rafts resting on over-consolidated clay deposits is presented. For this purpose, a series of plane-strain and three-dimensional analyses were performed and their results are compared with the available data in the literature. It was found that the percentage decrease in the total settlements with the addition of piles with respect to the unpiled case is very closely estimated by both the plane-strain and the three-dimensional, simpli...
A comparison of two dimensional and three dimensional finite element analysis for settlement behavior of piled raft foundations Kaltakcı, Volkan; Özkan, M. Yener; Department of Civil Engineering (2009) In this study, the settlement behavior of the piled raft foundations resting on overconsolidated clays under uniform loading, is investigated for different pile configurations and load levels. A total of 100 plane strain and three dimensional finite element analyses are carried out and the results of these analyses are compared both with each other and with the results presented by Reul & Randolph (2004). The material parameters used in the analysis are selected mainly referring to the previous studies ci...
