An Overland Flood Model for Geographical Information Systems
(Mdpi, 2020)
A variety of flood models and commercial flood simulation software are provided in the literature, with different accuracies and precisions changing from coarse to fine, depending on model structure and detailed descriptions ...
Retrofitting of Reinforced Concrete Beam-Column Joints by Composites-Part II: Analytical Study
(Amer Concrete Inst, 2019)
Beam-column joints (BCJs) in reinforced concrete (RC) structural systems are the critical regions, especially when they are subjected to high shear demands. According to earthquake reports and joint subassembly tests in ...
Stress resultants for wind girders in open-top cylindrical steel tanks
(Elsevier Sci Ltd, 2019)
Empty open-top cylindrical steel tanks are susceptible to buckling when subjected to external pressure due to wind or partial vacuum due to blocked vents. A "wind girder" is commonly used at the top of the tank wall to ...
Experimental and numerical studies for suitable infrared thermography implementation on concrete bridge decks
(Elsevier Sci Ltd, 2018)
Capturing the temperature difference between sound and defective parts under ambient conditions is key for infrared thermography (IRT) on concrete bridges. This study explores the favorable time windows for concrete bridge ...
Investigation of effective utilization of infrared thermography (IRT) through advanced finite element modeling
(Elsevier Sci Ltd, 2017)
Infrared thermography (IRT) has been used experimentally for concrete delamination detection. The past studies were conducted with limited experimental conditions, which make a difference in delamination detection. As a ...
Effects of Cross-sectional Geometry and Force Direction on Bending Strength and Modulus of Elasticity of Some Softwood Beams
(North Carolina State Univ Dept Wood & Paper Sci, 2019)
The effects of cross-sectional geometry and force direction on bending strength (MOR) and modulus of elasticity (MOE) were investigated in selected softwoods. The specimens were constructed of Scots pine (Pinus sylvestris), ...
X-ray CT monitoring of macro void development in mortars exposed to sulfate attack
(Techno-Press, 2018)
This study reports the results of nondestructive monitoring of macro void developments in mortars manufactured with both ordinary Portland cement and sulfate resistant cement. Two types of curing were utilized; tap water ...
Buckling assessment of cylindrical steel tanks with top stiffening ring under wind loading
(Routledge, 2019)
A stiffening ring is commonly used at the top of the tank wall to increase its strength against external pressure instability. Traditional design treatments generally consider cylindrical storage tanks under uniform external ...
Effect of Defect Size on Subsurface Defect Detectability and Defect Depth Estimation for Concrete Structures by Infrared Thermography
(Springer/Plenum Publishers, 2017)
This study aims to reveal the effect and correlation of delamination size and defect shape for using infrared thermography (IRT) through FE modeling to enhance the reliability and applicability of IRT for effective structural ...
Determination of Self-Healing Performance of Cementitious Composites Under Elevated CO2 Concentration by Resonant Frequency and Crack Opening Measurements
(Springer International Publishing Ag, 2018)
Global warming is a phenomenon that incontrovertibly affects daily lives of human beings in almost all aspects. Definitely, construction industry, especially concrete as most commonly used construction material, is not ...
