Reinforcing elements such as geotextiles or geogrids are widely used in retaining walls, slopes and embankments since they provide an economical and practical solution. A reinforced wall transitions into a slope as the slope angle with the horizontal decreases. Therefore, the design methodology transitions from lateral earth pressure theory to slope stability analyses. For slope stability problems both limit equilibrium and finite element methods are being used widely. In limit equilibrium solutions, the resisting force of the reinforcing elements can be considered in the equation of the factor of safety in several different ways. In finite element solutions, however, reinforcing elements have to be defined as some structural elements with certain stiffness. This study will focus on the two dimensional finite element and limit equilibrium analyses of reinforced slopes. A parametric study is presented for the comparison of the results obtained by limit equilibrium method and finite element method. The localization of shear strains and location of failure surfaces are investigated. The effect of vertical spacing of geogrids, cohesion of soil, friction angle of the soil, tensile capacity of geogrids, and length of geogrids on the factor of safety of the slopes are evaluated. The results of this study can be useful for better understanding the behavior, the possible failure modes and optimum design of reinforced soil slopes.

Technological characteristics of abrick masonry structure and their relationship with the structural behaviour / Aktaş, Yasemin Didem; Türer, Ahmet; Department of Archaeometry (2006) The aim of this study is to investigate the physical and mechanical properties of construction materials in relation with the structural behaviour of a historic structure. Within this framework, the brick masonry superstructure of Tahir ile Zuhre Mescidi, a XIIIth century Seljuk monument in Konya was selected as case study. The study started with the determination of the basic physical (bulk density, effective porosity, water absorption capacity), mechanical (modulus of elasticity, uniaxial compressive stre...
Numerical Study on CFRP Strengthening of Reinforced Concrete Frames with Masonry Infill Walls Akin, Emre; Ozcebe, Guney; Canbay, Erdem; Binici, Barış (American Society of Civil Engineers (ASCE), 2014-04-01) In the last decade, a new strengthening methodology has been developed for reinforced concrete (RC) frames with hollow clay tile (HCT) infill walls by means of diagonally applied carbon fiber-reinforced polymer (CFRP) fabrics. In the experimental part of a study conducted by the authors, this user-friendly methodology was experimentally investigated considering different aspect (height/width) ratios of the infill walls. In this study, first a numerical model of the FRP strengthened infill walls strengthened...
Investigation of the effect of soil structure interaction on the behavior of concrete faced rockfill dams and assessment of current analysis methodologies Erdoğan, Emrah Erşan; Arıcı, Yalın; Department of Civil Engineering (2012) CFRD (Concrete Faced Rockfill Dam) construction becomes more frequent recently not only because of its secure nature, but also its economical cost where its built up material is feasible to obtain. Although CFRDs are known to be safe compared to other dam types, it is behavior during an earthquake loading still not a well-known aspect since it is mostly constructed in regions of low seismicity until now. Considering this fact, this study‟s primary purposes are set to find the mathematical model size of a “l...
Analysis of RC walls with a mixed formulation frame finite element Sarıtaş, Afşin (2013-10-01) This paper presents a mixed formulation frame element with the assumptions of the Timoshenko shear beam theory for displacement field and that accounts for interaction between shear and normal stress at material level. Nonlinear response of the element is obtained by integration of section response, which in turn is obtained by integration of material response. Satisfaction of transverse equilibrium equations at section includes the interaction between concrete and transverse reinforcing steel. A 3d plastic...
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...
