ABAQUS Modelling and Experimental Tests Comparison for Certain Classes of Composite Isolated Joints
(
Qatar University Press
, 2023 , Conference Paper)
Depending on the type of configuration and connector arrangement, beam-to-column end-plate joints can be rigid, semi-rigid, or pinned. Fully restrained joints are required for rigid frames in which it is anticipated that ...
Along-Wind Aerodynamic Forces on a Rectangular Plan Building in Vicinity of a Gently Sloped Two-Dimensional Hill
(
Qatar University Press
, 2023 , Conference Paper)
Many engineering applications, such as wind energy distribution for optimum site selection for wind farms, pollutant dispersion, forest fire propagation and wind loads on structures in hilly terrains require a thorough ...
The Effect of Atrium on the Thermal Comfort in Buildings in Hot Arid Zones
(
Qatar University Press
, 2023 , Conference Paper)
The atrium is an open interior space that may be linked to the external environment; it is becoming more and more popular and a key element in the architectural design of many buildings, due to its attractive and symbolic ...
Production of Self-healing Concrete using Gum Arabic for Immobilizing of Bacterial Spores on Sand
(
Qatar University Press
, 2023 , Conference Paper)
This paper studies the feasibility of producing self-healing concrete by immobilization of bacteria on the sand. In this study, the Gum Arabic (Acacia Senegal) was used to immobilize bacterial spores and its nutrient ...
Experimental Investigation on the Flexural Capacity of Reinforced Concrete Beams with Treated Wastewater and Recycled Concrete Aggregates
(
Qatar University Press
, 2023 , Conference Paper)
Eco-friendly concrete is the most recommended sustainable option to reduce the excessive diminution of concrete natural resources and the high generation of greenhouse gas emissions. Therefore, the present study explores ...
Modeling Thermal Conductivity, Thermal Diffusivity and Specific Heat of Asphalt Concrete Using Beta Regression and Mixture Volumetrics
(
Qatar University Press
, 2023 , Conference Paper)
The main objective of this paper is to develop predictive models using Beta regression for laboratory-prepared hot mix asphalt (HMA) specimens' thermal properties, including thermal conductivity (TC), thermal diffusivity ...
Numerical Study on the Pullout Behavior of Steel Fibers in Cement-Based Composites
(
Qatar University Press
, 2023 , Conference Paper)
The interaction between steel fiber and surrounding cement-based matrix and concrete materials is crucial in the behavior of Steel Fiber-Reinforced Concrete (SFRC). This interaction is generally measured through a single ...
Sustainability Driven Strategy for Achieving Sustainable Infrastructure: Musaimeer Pumping Station and Outfall Project
(
Qatar University Press
, 2023 , Conference Paper)
The increasing emphasis on global sustainability issues such as climate change, loss of biodiversity, deforestation, and water scarcity has provided a strong mandate for the construction industry to incorporate sustainable ...
Launching a 148m-Long Tunnel Boring Machine from a 15m-Inner Diameter Shaft
(
Qatar University Press
, 2023 , Conference Paper)
The city of Doha has grown and expanded rapidly in the last 20 years, but this growth has strained the country's infrastructure, including its aging sewerage system and treatment facilities. ASHGHAL has therefore launched ...
The Use of Demolished Concrete Lumps (DCL) in Rectangular CFSTs Under Flexure
(
Qatar University Press
, 2023 , Conference Paper)
This paper investigates the flexural performance of rectangular concrete-filled steel tube (CFST) beams that are partially incorporated with demolished concrete lumps (DCLs). In total, three CFST beams were prepared and ...
