A comparison on the double cantilever beam and short rod fracture toughness test results of Ankara andesite

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...
A comparative study on the nonlinear behavior of chevron and suspended zipper braced steel frames Özçelik, Ahmet Yiğit; Sarıtaş, Afşin; Department of Civil Engineering (2010) Chevron braced steel frames require large beams to redistribute the unbalanced vertical forces exerted on the beams after brace buckling. A new frame configuration similar to chevron brace was proposed in literature, where zipper columns were attached between mid-spans of the beams from second to top story. During severe ground motion, the unbalanced vertical forces caused by buckling of lower story braces are in this case redistributed to the upper story braces by these zipper columns. Consequently, all st...
A study on the effect of pipe - soil relative stiffness on the behaviour of buried flexible pipes Bircan, Mehmet; Özkan, M. Yener; Department of Civil Engineering (2010) In this study, the effect of pipe-soil relative stiffness on the behaviour of buried flexible pipes was investigated considering the pipe size, material type, stiffness, pipe-soil and natural soil-backfill interfaces and geometry of the trench using the finite element method. For this purpose, a parametric study was conducted to examine the effect of different variables on the resulting earth loads and deformations imposed on the buried pipes. Various types of trench pipe-soil cases were analysed for a cert...
A numerical study on response factors for steel wall-frame systems Arslan, Hakan; Topkaya, Cem; Department of Civil Engineering (2009) A numerical study has been undertaken to evaluate the response of dual systems which consist of steel plate shear walls and moment resisting frames. The primary objective of the study was to investigate the influence of elastic base shear distribution between the wall and the frame on the global system response. A total of 10 walls and 30 wall-frame systems, ranging from 3 to 15 stories, were selected for numerical assessment. These systems represent cases in which the elastic base shear resisted by the fra...
An evaluation study on instrumentation system of Cindere dam Sezgin , Özgün İlke; Yanmaz, Ali Melih; Department of Civil Engineering (2008) In this study, the first hardfill dam in Turkey, Cindere Dam, is evaluated regarding current and alternative measurement systems in detail. Cindere Dam is a notable project, especially with its height as an example of hardfill dam, not only in Turkey but also in the world. First, the current instrumentation system of Cindere Dam is evaluated as a whole with reference to the parameters measured, instruments and data acquisition system. Second, an alternative instrumentation system is developed by using addit...
