Optimization of fly ash particle size distribution for cementitious systems with high compactness
(Elsevier Sci Ltd, 2019)Compactness is of special importance for aggregates in concrete; however, the particle-size distribution (gradation) of powdery ingredients is commonly disregarded especially for pozzolanic materials such as fly ash. Without ... -
Optimizing a fuzzy logic traffic signal controller via the differential evolution algorithm under different traffic scenarios
(Sage Publications Ltd, 2016)This study aims at optimizing fuzzy logic controller (FLC) triangle membership functions (MFs) for different traffic volumes via differential evolution (DE). To achieve this goal, a new FLC with a red time limiter, which ... -
Optimizing of phase plan, sequence and signal timing based on flower pollination algorithm for signalized intersections
(SPRINGER, 2020)The purpose of this study is to develop a control system that optimizes the phase plan, sequence and signal timing using the flower pollination algorithm (FPA). At the same time, it is aimed to improve the fixed-time control ... -
Performance of cement mortars replaced by ground waste brick in different aggressive conditions
(Univ Chemistry & Technology, Prague, 2011)This article investigates the sulphate resistance of cement mortars when subjected to different exposure conditions. Cement mortars were prepared using ground waste brick (GWB) as a pozzolanic partial replacement for cement ... -
Performance of engineered cementitious composites under drop-weight impact: Effect of different mixture parameters
(Ernst & Sohn, 2019)Current research focuses on the experimental and numerical determination of impact performance of engineered cementitious composites (ECC). Performance assessment of ECC beams with different mixture parameters was made. ... -
Physical and permeability properties of cementitious mortars having fly ash with optimized particle size distribution
(Elsevier Sci Ltd, 2019)Gradation of powder materials is often avoided in pozzolanic materials, such as fly ash and slag. Without good gradation, powder materials result in high void ratios similar to the case of aggregates and the products ... -
Prediction of the effect of varying cure conditions and w/c ratio on the compressive strength of concrete using artificial neural networks
(Springer London Ltd, 2013)The present study aims at developing an artificial neural network (ANN) to predict the compressive strength of concrete. A data set containing a total of 72 concrete samples was used in the study. The following constituted ... -
Recommendations for calculation of strengthened brick walls with perforated plates
(Gazi Univ, Fac Engineering Architecture, 2019)There are many studies relating to the strengthening of infill brick walls, which contribute partially to the resistance against the seismic forces, by using different methods and materials to make them behave similarly ... -
Recovery Of Phosphogypsum In Economy In Building Materialwaste
(Gazi Univ, Fac Engineering Architecture, 2015)Phosphogypsum, the storage of which damages the ecological balance, has limited use due to its contamination aspect. However, it is possible to eliminate its impurities through raffination methods, such as washing and ... -
Restrained shrinkage cracking of self-consolidating concrete roads
(Walter De Gruyter Gmbh, 2018)The present study is dedicated to investigate the liability of continuously reinforced concrete pavement (CRCP) cast with self-consolidating concrete (SCC) to restrained shrinkage cracking and the values of restraint ... -
Retrofit of Non-Ductile RC Frames with Precast Concrete (PC) Wall Panels
(Multi-Science Publ Co Ltd, 2011)An economic, structurally effective and practically applicable strengthening method had been developed for reinforced concrete (RC) framed buildings. This study presents the test results on strengthening of deficient RC ... -
Role of Nanosilica on the Early-Age Performance of Natural Pozzolan-Based Blended Cement
(Amer Concrete Inst, 2018)This investigation focused on the microstructural, workability, mechanical, and hyration evolution of blended cements composed of natural pozzolan with nanosilica (NS). In Turkey, the most common supplementary cementitious ... -
Rollover instability of precast girders subjected to wind load
(Ice Publishing, 2017)The use of longer and deeper precast concrete girders has created concern regarding their rollover instability, particularly during construction. Current design and construction specifications do not provide any specific ... -
Seismic performance of R/C structures under vertical ground motion
(Techno-Press, 2017)The effects of the vertical component of a ground motion on the earthquake performances of semi-ductile high-rise R/C structures were investigated in the present study. Linear and non-linear time-history analyses were ... -
Seismic risk estimation of the Kirikkale province through street survey based rapid assessment method (SSRA)
(Techno-Press, 2018)The seismic vulnerability of Turkey is relatively high due to its active fault systems with potential to create destructive earthquakes. Thus, reducing the loss of life and property, the number of the earthquake-prone ... -
Seismic strengthening of reinforced concrete frames by precast concrete panels
(Ice Publ, 2011)An innovative occupant-friendly retrofitting technique has been developed for reinforced concrete (RC)-framed structures which constitute the major portion of the existing building stock. The idea is to convert the existing ... -
