The improvement in design technologies has enhanced the use of different fill materials in construction of the embankment dams. Rockfill is one of the most preferred fill materials for embankment dam. Also, use of different fill material such as sand-gravel has been preferred in recent years. Previous studies on concrete faced sand-gravel fill dam (CFSGD), results of the laboratory experiments and in-situ testing analysis display that using sand-gravel as a fill material is not only cost-effective but also safe and provides high quality natural construction material. In this study, settlement of Karacasu Dam, which is the first concrete faced sand-gravel fill dam in Turkey, is examined for “end of construction” and “reservoir impoundment” loading conditions. Deformations are determined by computing two-dimensional finite element analyses. Hardening soil model is utilized to obtain non-linear, stress dependent and inelastic behavior of the sand-gravel fill material. Deformations which are calculated by finite element analyses, are compared with the data observed by General Directorate of State Hydraulic Works (DSİ) for both end of the construction and reservoir impoundment periods. The comparison of the results indicates that calculated deformations are generally compatible with the observed ones.

Finite element analysis of deformation behavior of concrete faced Konya Afşar Hadimi dam and comparison of results with measurements
Kardeş, Doğuşcan; Çokça, Erdal; Department of Civil Engineering (2019)
To eliminate the problem of scarcity of appropriate fill material in the vicinity of construction site, concrete faced dam is a commonly preferred alternative for embankment dams. Functioning as an impervious membrane, the concrete face makes it possible to use dumped rockfill, compacted rockfill or sand-gravel fill as the dam body material. In this study, deformation behavior of Konya Afşar Hadimi Dam, which is a concrete faced rockfill dam, was investigated by finite element analyses using Plaxis and Mida...
Vulnerability assessment of reinforced concrete moment resisting frame buildings
Erduran, Emrah; Yakut, Ahmet (2007-04-01)
A detailed seismic performance assessment procedure has been developed for reinforced concrete (RC) frame buildings with masonry infill walls. The procedure is based on member damage functions, in terms of interstory drift ratios. These functions are developed for the primary components, namely, columns, beams, and infill walls. For developing these functions, analytical investigations to determine the influence of several parameters on the damageability of components were combined with experimental data. A...
Mechanical properties of epoxy matrix composite reinforced with multi-walled carbon nanotubes
Yüceer, Kevser.; Çöker, Demirkan; Department of Aerospace Engineering (2019)
Improving usage preference of composite material in the aerospace industry brings the requirement of improving mechanical properties of the material. In this thesis, mechanical improvement of epoxy composite materials is analyzed with contribution of functionalized multi-walled CNT with carboxyl group (-COOH) and non-functionalized MWCNT with epoxy for CNT weight fractions of 0.8, 1.0, 1.2, 1.5 and 2.0 wt%. The nanomaterial is dispersed in epoxy resin by calendering mixing method. Functionalization of CNT p...
