Vertical load test and cyclic horizontal load test on a 3-pile piled raft model were carried out in dry sand model ground at 1-g field to investigate vertical and horizontal bearing mechanisms of the piled raft model. Load tests on the raft and single pile were also carried out separately to investigate their interactions on the piled raft. Numerical modelling of the load tests were carried out, aiming at obtaining more insight into the behaviour of the piled raft subjected to vertical and horizontal loading. A FEM software, PLAXIS 3D, was used for this purpose. The hardening soil model was employed for modelling the sand behaviour. The soil parameters were estimated from a series of consolidated drained triaxial tests of the sand. It is shown from the load tests that the behaviour of the piled raft is not mere summation of the components, but is largely influenced by the interaction of the components as well as the level of the applied load.

Numerical analyses of load tests on model foundations in dry sand Unsever, Y. S.; Matsumoto, T.; Özkan, M. Yener (2015-01-01) In this study, a series of vertical and cyclic horizontal load tests on 3-pile piled raft model were carried out in dry sand to investigate the piled raft behaviour under combined loads. Also, numerical modelling of experiments were carried out by using FEM software, PLAXIS 3D. Hardening soil model was employed to model the sand, and elastic model was used for the pile and the raft. Soil parameters were estimated from consolidated drained triaxial tests carried on the sand samples and pile parameters were e...
Seismic behaviour of roller compacted concrete dams under different base treatments Gharibdoust, Ali; ALDEMİR, ALPER; Binici, Barış (Informa UK Limited, 2019-09-09) The effect of base roughness on the seismic behaviour of roller compacted concrete gravity dams were investigated by pseudo-dynamically testing two 1/75 scaled specimens with smooth and rough base treatments. Both specimens were tested under the effect of three different hazard level earthquakes and also a pushover experiment was conducted to obtain the capacity curve of each specimen. The smooth base specimen exhibited significant sliding under the effect of the maximum credible earthquake motion. In contr...
Pseudo-dynamic testing of a concrete gravity dam Aldemir, Alper; Binici, Barış; Arıcı, Yalın; Kurç, Özgür; Canbay, Erdem (2015-09-01) Inspired from the simplified single degree of freedom modeling approach used in the preliminary design of concrete gravity dams, a pseudo-dynamic testing method was devised for the seismic testing of a concrete gravity dam section. The test specimen was a 1/75 scaled section of the 120-m-high monolith of the Melen Dam, one of the highest concrete gravity dams to be built in Turkey. The single degree of freedom idealization of the dam section was validated in the first stage of the study using numerical simu...
Numerical simulation of scour at the rear side of a coastal revetment Şentürk, Barış Ufuk; Guler, Hasan Gokhan; Baykal, Cüneyt (2023-05-01) This paper presents the results of a numerical modeling study on the scouring of unprotected rear side material of a rubble mound coastal revetment due to the overtopping of solitary-like waves utilizing a coupled hydro-morphodynamic computational fluid dynamics (CFD) model. Three cases having various wave heights are tested with six different turbulence models together with different wall functions. The hydrodynamic results (free-surface elevations, overtopping volumes, and jet thicknesses) and morphologic...
Numerical investigation of natural convection from vertical plate finned heat sinks Çakar, Kamil Mert; Albayrak, Kahraman; Department of Mechanical Engineering (2009) The steady-state natural convection from vertically placed rectangular fins is investigated numerically by means of a commercial CFD program called ICEPAK. The effects of geometric parameters of fin arrays on the performance of heat dissipation from fin arrays are examined. In order to simulate the different fin configurations and compare the results with literature, two experimental studies from literature are selected. Optimum fin spacing for both studies are found numerically and compared with experiment...
