In this study, an experimental program was established to understand the behaviour of FRP-confined low strength cylindrical and square-section concrete columns under temperature changes. The experimental program was divided into four groups. First group of specimens were kept under room temperature and used as control specimens. In the second group, specimens were exposed to predetermined heating-cooling cycles in a specially designed environmental test chamber. Third group of specimens were placed in water, kept in the environmental test chamber, and subjected to the same heating-cooling cycles. In the last group, specimens were subjected to outdoor exposure in Ankara, Turkey. After the aging tests, specimens were tested under uniaxial compression to determine the change in their mechanical properties.

Importance of Degrading Behavior for Seismic Performance Evaluation of Simple Structural Systems Erberik, Murat Altuğ (Informa UK Limited, 2011-01-01) This study focuses on effect of degradation characteristics on seismic performance of simple structural systems. Equivalent single degree of freedom systems are used for which the structural characteristics are taken from existing reinforced concrete (RC) frame buildings. Simulation of degrading behavior is achieved by considering actual experimental data. To obtain the seismic response of degrading structural systems, two different approaches are used: inelastic spectral analysis and fragility analysis. Ac...
Elastic Response of Heat Generating Rod at a Variable Generating Rate Eraslan, Ahmet Nedim; Varlı, Ekin (2014-09-28) The aim of this study is to develop a computational model to analyze thermally induced stress and deformation in a heat generating solid rod. The rod is initially at zero temperature, but for times greater than zero heat is generated internally at both space and time dependent rate. As the rod is heated up slowly an uncoupled solution is realized. The heat conduction equation with a variable generation rate is solved by a finite element collocation method. Two different generation rates are handled. The num...
Behaviour of the reinforced concrete face slabs of concrete faced rockfill dams during impounding Arıcı, Yalın (2013-09-01) The primary goal of this study was to examine the relative effects of various factors that affect the cracking of the face slab of a concrete faced rockfill dam (CFRD). Rigorous simulation of the construction and impoundment stages were conducted in sequential phases during which the rockfill and the rockfill-face slab interface were modelled with elasto-plastic models that were calibrated to existing test data. The face slab was modelled using embedded reinforcements with a total strain crack model. The re...
Investigation of radiative heat transfer in freeboard of a 0.3 MWt AFBC test rig Kozan, M; Selçuk, Nevin (2000-01-01) Based on the analysis of measured data on flow rates, concentrations and temperatures taken during steady state operation of a lignite-fired 0.3 MWt Atmospheric Fluidized Bed Combustor (AFBC) test rig, radiative exchange in freeboard of the combustor was modeled by using a well-stirred enclosure model in conjunction with Radiosity-Irradiation Method (RIM). Radiative properties of the particle laden combustion gases were calculated by assuming grey radiation behaviour for both particles and gas, and using Le...
Upgrading of slab-column connections using fiber reinforced polymers Binici, Barış (Elsevier BV, 2005-01-01) The results of an experimental program on upgrading of reinforced concrete slab-column connections subjected to monotonic shear and unbalanced moment transfer are presented in this study. Externally installed carbon fiber reinforced polymer (CFRP) stirrups acting as shear reinforcement around the slab-column connection area were used with two patterns of CFRP arrangements. It was found that the proposed method resulted in punching shear capacity increases up to 60% relative to the specimen without any stren...
