Hybrid strategic groups in construction
BUDAYAN, CENK; Dikmen Toker, İrem; Birgönül, Mustafa Talat (2011-09-01)
The aim of strategic group analysis is to question the existence of clusters of firms that implement a similar strategic perspective and performance implications of strategic group membership. Strategic group analysis is usually carried out by conducting statistical cluster analysis in which a company is assigned to a single strategic group. However, all the companies within the same group do not usually adhere to the strategic group recipe at the same degree. Hybrid firms develop their own strategic postur...
Comparative evaluation of steel mesh, steel fiber and high performance polypropylene fiber-reinforced concrete in panel/beam tests
Ceylan, Semih; Turanlı, Lütfullah; Department of Civil Engineering (2014)
Comparison of concrete mixtures containing steel mesh, steel fiber and polypropylene fibers were evaluated in terms of toughness, flexural strength, compressive strength and split tensile strength. Five types of concrete were prepared with steel mesh, steel fiber and polypropylene fiber with the identical water/cement (w/c) ratio and the identical workability. 10x60x60 cm plates, 8x8x32 cm beams and 10x20 cm cylindrical concrete specimens were prepared. Compressive strength, split-tensile strength and tough...
Performance of concrete gravity dams under earthquake effects
Soysal, Berat Feyza; Arıcı, Yalın; Department of Civil Engineering (2014)
Concerns about the seismic safety of gravity dams have increased with the construction of numerous new dams in the developing world as well as the need for the evaluation of existing dam stock in the developed countries. The common procedure for the design of concrete gravity dams has been linear analyses: there is scant experience on the design of such systems using nonlinear analyses as the post-linear behavior and performance limits of gravity dam monoliths are not well known. This study is focused on th...
Overlapping lattice modeling for concrete fracture simulations using sequentially linear analysis
Aydın, Beyazıt Bestami; Binici, Barış; Tuncay, Kağan; Department of Civil Engineering (2017)
Estimation of the crack location and width in concrete structures is important due to the sustained damage in structures as a result of extreme loads and aging. The location and width of cracks are the most influential parameters for making decisions on the structure service life. Despite significant developments, the computational modelling of concrete fracture initiation and propagation are still challenging tasks. Many different numerical approaches, most of them based on finite element analysis, have be...
Evaluation of the Ground Motion Scaling Procedures for Concrete Gravity Dams
SOYSAL, BERAT FEYZA; Ay, Bekir Özer; Arıcı, Yalın (Elsevier BV; 2017-09-13)
The seismic safety of dam structures is often evaluated using time history analyses conducted with a limited number of ground motions. The selection and scaling of the ground motions is usually the most effective factor determining the results of the safety assessment. The inherent variability in the ground motion as well as the difficulty of conducting the analyses for a large number of ground motions renders the selection as the most important factor in the analysis results. The guidelines for the nonline...
