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 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 ...
Synthesis of Calcium Nitrate Self-Healing Microcapsules Using Aerosol OT Hexane Solution for Cementitious Materials
(
Qatar University Press
, 2023 , Conference Paper)
Calcium nitrate synthesis of in urea-formaldehyde shell has recently been used to produce self-healing microcapsules for construction applications. The original synthesis was based on water-in-oil emulsion with sulfonic ...
Bio-Based Self-Healing Concrete for Sustainable and Durable Concrete Infrastructure
(
Qatar University Press
, 2023 , Conference Paper)
In this study, bio-self-healing concrete was manufactured using a natural phenomenon called microbial-induced calcium carbonate precipitation (MICP). The bacillus cereus bacteria isolated from Qatari soil was used for this ...
Top-Down Construction Method: A Case Study For Underpass Structure in Qatar
(
Qatar University Press
, 2023 , Conference Paper)
The Cut and Cover construction method has been applied to build several underpass structures within the expressway programme of the Highway Projects Department, Public Works Authority, Qatar. Booming in the construction ...
A Bibliometric Study of Visual Quality Research in the Context of Urban Open Spaces
(
Qatar University Press
, 2023 , Conference Paper)
Visual quality assessment has received much attention in research by forest management and landscape researchers after the mid-twentieth century with the advent of legal frameworks enacted to protect natural resources, ...
Development of a Comprehensive Pavement Design System for Roads in Wind and Solar Farms
(
Qatar University Press
, 2023 , Conference Paper)
This paper briefly, illustrates the structure and contents of an ongoing research program aimed at developing a set of procedures and tools to be used for the design of pavements in renewable energy projects and mainly in ...
A Static and Free Vibration Analysis of Porous Functionally Graded Beams
(
Qatar University Press
, 2023 , Conference Paper)
In this work, the static and free vibration analysis of functionally graded (FG) porous beams is investigated using a new higher-order shear deformation model (HSD). The porosity that develops naturally during the fabrication ...
Modeling Short-Term Deflection of Reinforced Concrete Slabs using the Layered Approach
(
Qatar University Press
, 2023 , Conference Paper)
This paper examines the short-term deflection of reinforced concrete slabs taking the tension-stiffening phenomenon into account. The main goal of this study is to develop a model that predicts the deflection of one-way ...
Tunnel Surveying Works: A Technical Challenge of 10 km-long tunnel under the Arabian Gulf-Qatar
(
Qatar University Press
, 2023 , Conference Paper)
The Musaimeer Pump Station & Outfall Tunnel project (MPSO) was constructed as one of the longest Outfall tunnels in the World with a total length of 10.189m and at the same time being the longest undersea tunnel in the ...
