Flower pollination algorithm approach for the transportation energy demand estimation in Turkey: model development and application
(Taylor & Francis Inc, 2018)
This study proposes a new optimization technique to estimate the Transportation Energy Demand (TED) employing the Flower Pollination Algorithm (FPA). The TED estimation models were developed based on three parameters, which ...
Effects of the use of the surface spectrum of a specific region on seismic performances of R/C structures
(Springer, 2018)
The present study pertains to the estimation of the significance of the use of the local acceleration spectrum of a region rather than the design spectra based on the linear time-history analyses of real structures in the ...
Effects of sulfate on cement mortar with hybrid pozzolan substitution
(Elsevier - Division Reed Elsevier India Pvt Ltd, 2018)
Sulfate is one of the most important chemical risks which affect the durability of concrete and reinforced concrete structures. Therefore, this study investigates the effects of sulfate on blended cement mortars. In this ...
Flow Characteristics in the Wake Region of a Finite-Length Vegetation Patch in a Partly Vegetated Channel
(Mdpi, 2018)
Aquatic vegetation in rivers and coastal regions controls the flow structure in terms of mean velocity and turbulence. The vegetation in the flow affects the transportation of nutrients, microbes, dissolved oxygen, sediment, ...
An investigation on the evaluation of dynamic soil characteristics of the Elazig City through the 1-D equivalent linear site-response analysis
(Springer Heidelberg, 2019)
Consideration of the effects of the site response in the design of civil structures systems is of important to mitigate the damages to a certain extent on structures and the environment. Hence, it is relatively crucial to ...
Investigation of the liquefaction potential of fiber-reinforced sand
(Techno-Press, 2019)
In the present, the liquefaction potential of fiber-reinforced sandy soils was investigated through the energy-based approach by conducting a series of strain-controlled cyclic simple shear tests. In the tests, the effects ...
Self-Sensing of Flexural Damage in Large-Scale Steel-Reinforced Mortar Beams
(Amer Concrete Inst, 2019)
The majority of self-sensing studies conducted in current literature uses small-scale specimens without steel reinforcement which might be misleading for damage monitoring in actual structures. To account for this, herein, ...
Dimensional stability of deflection-hardening hybrid fiber reinforced concretes with coarse aggregate: Suppressing restrained shrinkage cracking
(Ernst & Sohn, 2019)
High Performance Fiber Reinforced Concretes (HPFRCs) with deflection-hardening capability are relatively novel materials with high damage tolerance. However, mixture proportions of such materials are mostly designed with ...
Impact resistance of deflection-hardening fiber reinforced concretes with different mixture parameters
(Ernst & Sohn, 2019)
The impact behavior of deflection-hardening High Performance Fiber Reinforced Cementitious Concretes (HPFRCs) was evaluated herein. During the preparation of HPFRCs, fiber type and amount, fly ash to Portland cement ratio ...
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 ...
