Channel shear connectors are fairly new alternatives to the shear connectors. In this thesis two of the previously done experimental studies were simulated using FEM. First, push-out tests consisted of ten specimens which include European channel sections as shear connectors were modeled in ANSYS. The models with simplistic materials and 2D elements were analyzed. Analysis results were compared with the experimental results. Comparisons showed that, 2D models with bilinear materials were sufficient enough to provide practical ultimate capacity predictions. Second, full-scale beam test with channel shear connectors were simulated. Experiments included four specimens with differentiating connector numbers. The general aim was to investigate the partial and full composite action. 3D FE models were created with several concrete modeling approaches and difficulties in modeling were mentioned. One stable concrete model was found and selected for use. Experimental results and analysis result were compared. Also comments were made on model behavior. In conclusion, FE modeling details were reviewed and criticized.

Design of a Re-configurable dual frequency microstrip antenna with integrated RF MEMS switches
Onat, Sinon; Ünlü, Mehmet; Alatan, Lale; Demir, Şimşek; Akın, Tayfun (2005-07-08)
The complete design of a re-configurable dual frequency antenna structure, including its integrated RF MEMS switches and their actuation lines together with a CPW feed, is introduced. The number of switches used in the inset is decreased compared to the hybrid design we presented previously (Onat, S. et al., IEEE Int. Antennas and Propag. Symp., vol.2, p.1812-15, 2004). Instead of utilizing available RF MEMS switches, new switches suitable for this application are designed. Two different switch configuratio...
Analytical modeling of fiber reinforced composite deep beams
Yağmur, Eren; Burak Bakır, Burcu; Department of Civil Engineering (2018)
Discrete fibers are often used as reinforcement to increase the tensile and shear strengths of concrete. For many years, the behavior of fiber reinforced composite members has been investigated both experimentally and analytically. The influence of fibers on the behavior of shear critical members is quite significant, therefore, it is inevitable to develop a method, which estimates the shear strength of fiber reinforced composite deep beams realistically. This is why one of the main objectives of this study...
Development of Bolted Flange Design Tool Based on Artificial Neural Network

<jats:p>Finite element analysis (FEA) of bolted flange connections is the common methodology for the analysis of bolted flange connections. However, it requires high computational power for model preparation and nonlinear analysis due to contact definitions used between the mating parts. Design of an optimum bolted flange connection requires many costly finite element analyses to be performed to decide on the optimum bolt configuration and minimum flange and casing thicknesses. In this study, very fast resp...
ANALYSIS OF GROUND FAULT CURRENT DISTRIBUTION ALONG UNDERGROUND CABLES
Güven, Ali Nezih (1986-10-01)
It is important to determine the segment-by-segment distribution of the fault current in a multigrounded power network for better power system operation and grounding structure design. In this paper, a new method for the analysis of ground fault current distribution along underground cables (and/or overhead lines) is presented. The method is sufficiently accurate and comprehensive to simultaneously consider all the significant variables. The equivalent circuit developed utilizes both lumped and distributed ...
Test method for determining the shear modulus of elastomeric bearings
Topkaya, Cem (American Society of Civil Engineers (ASCE), 2002-06-01)
The shear modulus of the elastomer is the most important material property related to the behavior of elastomeric bearings used principally at supports in bridges. Current methods for determining the shear modulus usually require small test samples cut from manufactured bearings. Such tests are costly, do not necessarily represent the performance of the full-size bearing, and are destructive. A new shear test method, called the inclined compression test, is reported that is nondestructive and only requires ...
