Analysis of the relationship between LSTM network traffic flow prediction performance and statistical characteristics of standard and nonstandard data
(WILEY, 2020)The effectiveness of road traffic control systems can be increased with the help of a model that can accurately predict short-term traffic flow. Therefore, the performance of the preferred approach to develop a prediction ... -
Behavior and strength of hidden Rc beams embedded in slabs
(ELSEVIER, 2020)Reinforced concrete (RC) beams protrude from the ceiling, unless there is an infill wall beneath. Sometimes the construction of these beams is avoided due to aesthetic concerns, and instead a reinforcement arrangement with ... -
Enhancement on mechanical and durability performances of binary cementitious systems by optimizing particle size distribution of fly ash
(SPRINGERNATURE, 2020)Fly ash is a well-known supplementary cementitious material that is the by-product of coal-fired thermal power plants. The contribution of fly ash to the enhancement of the mechanical and durability properties of cementitious ... -
Investigation on variables affecting bond strength between FRP reinforcing bar and concrete by modified hinged beam tests
(ELSEVIER SCI LTD, 2020)Abstract The bond strength between FRP reinforcement and concrete significantly affects the load bearing capacity and deformation ability of an FRP reinforced concrete member subjected to bending. There are numerous ... -
Engineering plastic gripping mechanism for tension testing of FRP bars
(SAGE PUBLICATIONS LTD, 2020)A new grip adaptor, made of an engineering plastic Cast Polyamide 6 (PA6G), was developed for tension testing of FRP reinforcing bars. The new adaptor offers several advantages over conventional anchors, including the ease ... -
Impact behaviour of nanomodified deflection-hardening fibre-reinforced concretes
(ICE PUBLISHING, 2020)The behaviour of concrete under sudden impact loads is complex. Moreover, very little is known about the impact behaviour of high-performance fibre-reinforced concretes (HPFRCs). To account for this, nanomodified ... -
The effect of lane blockage on signalised intersection performance - analysing and modelling
(SAICE-SAISI, 2020)Unexpected stops or entry/exit manoeuvres of vehicles on the road may cause the related lane to become blocked. When this blocking happens in a signalised intersection zone, it also affects intersection performance. ... -
Gamma ray and neutron shielding characteristics of polypropylene fiber-reinforced heavyweight concrete exposed to high temperatures
(ELSEVIER SCI LTD, 2020)The residual properties of shielding structures need to be redefined after exposure to elevated temperatures due to their probable radiological hazards on biodiversity. In this study, the effect of high temperatures on ... -
Effects of Mixture Design Parameters on the Mechanical Behavior of High-Performance Fiber-Reinforced Concretes
(ASCE-AMER SOC CIVIL ENGINEERS, 2020)The main purpose of this research is to assess the influence of different design parameters on the mechanical performance of high-performance fiber-reinforced concrete (HPFRC) mixtures. Special attention is also paid to ... -
A study on ASR mitigation by optimized particle size distribution
(ELSEVIER SCI LTD, 2020)In this study, the effect of alkali-silica reaction on binary cementitious composite systems incorporating fly ash or slag having optimized particle size distribution has been investigated. Specimens have been exposed to ... -
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 ... -
Estimating the Properties of Ground-Waste-Brick Mortars Using DNN and ANN
(Tech Science Press, 2019)In this study, deep-neural-network (DNN)- and artificial-neural-network (ANN)- based models along with regression models have been developed to estimate the pressure, bending and elongation values of ground-brick (GB)-added ... -
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 ... -
Evaluating solid waste landfill site selection using multi-criteria decision analysis and geographic information systems in the city of Elazig, Turkey
(Pamukkale Univ, 2019)Solid waste landfill site selection is a relatively complex process and depends on several criteria and official regulations. In this study, the suitability of solid waste landfill site selection for the city of Elazig, ... -
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 ... -
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 ... -
