A simplified nonlinear fiber-based finite element model of steel-concrete partially composite beams utilizing channel type mechanical shear connectors is developed in OpenSees framework. The interaction between steel beam and concrete slab is accounted for by introducing nonlinear zero length elements and rigid links. The channel shear connector response used in numerical models is based on the previously obtained experimental response from pushout tests. Accuracy of the numerical models in predicting the response of beams is verified with the results of the previously conducted composite beam tests. The numerically predicted response agrees well with the experimental results over the entire range of load-deflection curves for both the fully composite and partially composite beams. The numerical models are also able to accurately predict the interface slip between steel beam and concrete slab when compared to the experimentally determined slip values, as well as the closed form slip predictions. Analysis results allowed the investigation of how the influence of steel and concrete damage is reflected on the overall load-deflection response of composite beams.

Analysis of specimen size effects in inclined compression test on laminated elastomeric bearings Topkaya, Cem (Elsevier BV, 2004-07-01) Inclined compression test method is a practical way of determining the shear modulus of full-size laminated elastomeric bearings. Performing full-size bearing tests requires high-capacity testing machines. It may be possible to cut the specimens into smaller sizes for testing purposes. Limited amount of experimental data show that specimen size has a significant effect on the measured shear modulus. In this paper, the Haringx shear weak column theory is used to identify the important geometric specimen prop...
Nonlinear mixing length model for prediction of secondary currents in uniform channel flows Aydın, İsmail (American Society of Civil Engineers (ASCE), 2009-01-29) A nonlinear turbulence model for numerical solution of uniform channel flow is presented. Turbulent stresses are evaluated from a nonlinear mixing length model that relates turbulent stresses to quadratic products of the mean rate of strain and the mean vorticity. The definition of the mixing length, based on a three-dimensional integral measure of boundary proximity, eliminates the need for solution of additional transport equations for the turbulence quantities. Experimental data from the literature for c...
Optimal load and resistance factor design of geometrically nonlinear steel space frames via tabu search and genetic algorithm DEĞERTEKİN, SADIK ÖZGÜR; Saka, M. P.; HAYALİOĞLU, MEHMET SEDAT (Elsevier BV, 2008-01-01) In this paper, algorithms are presented for the optimum design of geometrically nonlinear steel space frames using tabu search and genetic algorithm. Tabu search utilizes the features of short-term memory facility (tabu list) and aspiration criteria. Genetic algorithm employs reproduction, crossover and mutation operators. The design algorithms obtain minimum weight frames by selecting suitable sections from a standard set of steel sections such as American Institute of Steel Construction (AISC) wide-flange...
Contact mechanics problem between an orthotropic graded coating and a rigid punch of an arbitrary profile ARSLAN, ONUR; Dağ, Serkan (Elsevier BV, 2018-01-01) Singular integral equation (SIE) and finite element methods are developed for sliding contact analysis of a finite thickness orthotropic graded coating, which is perfectly bonded to an isotropic substrate. Orthotropic stiffness coefficients of the coating vary exponentially through the coating thickness. The coating is assumed to be loaded by a frictional rigid punch of an arbitrary profile. In the SIE formulation, governing partial differential equations are derived in accordance with the theory of plane e...
Isotropic-Kinematic Cyclic Hardening Characteristics of Plate Steels Shakeri, Ashkan (Springer Science and Business Media LLC, 2017-03-01) Cyclic hardening of metals is considered as one of the most important features that affects extremely the hysteresis behavior of steel structures. One approach to study this characteristic is dividing it into two components, including isotropic hardening and kinematic hardening, and defining any of these components for any type of metals by calibrated data obtained from experiments. However, the lack of these calibrated data on metals, restricts this approach. Therefore, in this paper the isotropic and kine...
