The coastal defense structures are constructed by various types of structural systems varying from traditional rubble mound types and concrete systems to more innovative systems. In recent applications the geotextile is used in some applications of coastal engineering a such as coastal erosion control or perforated breakwaters. The tubular concrete units can be prepared at site by using geotextile as formwork and construct a perforated structure by placing the tubes in a specified angle and spacing. The performance of this type of perforated structures depends on the wave (height, period, direction) and structure characteristics (i.e. water depth, structure angle, bottom slope, tube spacing).. In this study, a perforated vertical wall structure constructed by placing the geotextile tubes with an angle of 45 degrees to the longitudinal axis of the breakwater is tested in hydraulic experiments. The experiments are conducted in a wave flume at a certain water depth and sea bottom slope under regular wave conditions with perpendicular wave approach. The transmission and reflection characteristics of wave heights are investigated. The relation between the reflection/transmission coefficients and the wave/structure characteristics are presented. The performance of this type of perforated structures is discussed.

Seismic retrofit of buildings with backbone dampers
Shaban, Nefize; Ozdemir, Seda; Caner, Alp; Akyüz, Uğurhan (2017-01-01)
Dampers have been effectively used in new designs and seismic retrofit of old structures in many parts of the world. The common seismic retrofit practice in Turkey is almost purely based on stiffening the structure with additional shear walls or adding braces to limit the excessive seismic drifts. Such an approach usually results in expensive interior works and enlargements of foundations. The stiffening of the structure typically results in attracting more seismic force. Utilization of dampers as seismic p...
Simulation of damage propagation on massiveconcrete structures, the overlapping lattice model v.s.The finite element approach
Soysal, Berat Feyza; Arıcı, Yalın; Binici, Barış; Tuncay, Kağan (2017-10-11)
The increase in the computational power enables the performance based assessment of very large structures like concrete gravity dams. These assessments are usually carried out with the traditional finite element tools. The continuum based formulation of these analyses in the absence of costly re-meshing operations cast doubt on the performance assessment of such massive plain concrete structures given the primary output assessed for these analyses should be the crack propagation and opening on the dam body....
Behavior of reinforced concrete deep beam with web openings strengthened with (CFRP) sheet
Jasim, Waleed A.; Tahnat, Yazan B. Abu; Halahla, Abdulsamee M. (2020-08-01)
Deep beams are used in various applications in reinforced concrete (R.C.) structures. There have been continuous efforts to enhance and improve the performance of these crucial elements in (R.C.) structures by using several strengthening techniques such as using the carbon fiber-reinforced polymer (CFRP). However, by exploring the literature, none of the previously conducted experimental tests have studied the propagation of cracks beneath the (CFRP) sheets. In this research, the propagation of the first di...
Investigation of seismic isolation efficiency for building structures
Özdemir, Seda; Yakut, Ahmet; Ay, Bekir Özer; Department of Earthquake Studies (2016)
The main goal of this study is to assess the efficacy of seismic isolation for building type of structures with different structural systems, namely, dual systems and moment frame systems having also different number of floors. Specific to this study, the main parameters employed for efficacy assessment will be the interstorey drift ratio and floor acceleration since both structural and non-structural damage to be occured in a system are directly related to these two parameters. To assess the variations in inter...
Experimental investigation of structural systems made of sheathed cold-formed steel wall panels
Pehlivan, Barış Mert; Baran, Eray; Department of Civil Engineering (2023-1-12)
Cold-formed steel (CFS) structural systems are considered to be an innovative and newly developing construction method. Because of advantages such as lower fabrication periods, high strength/weight ratio and ease of construction, CFS structural systems have been used increasingly all around the world, including seismically active areas. Although there have been many studies in the literature, CFS structural systems are relatively new for the civil engineering practice and few existing specifications regardi...
