Mesaimeer pedestrian underpass is proposed under the live traffic of Sabah Al Ahmad Road, Doha, Qatar which consists of a four dual lane carriageway, in addition to diverge lanes, service road lanes and right turn lanes ...
Theoretical Simulation of Thermal Deformations in Concrete Beams Reinforced with Two Overlapped FRP Bars in Cold Regions
(
Qatar University Press
, 2023 , Conference Paper)
The thermal incompatibility in transverse direction between concrete and fiber reinforced polymer (FRP) bars may cause tensile circumferential cracks within concrete under low temperatures, and consequently, the failure ...
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 ...

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 ...
Early Thermal Cracking Control of Concrete Structures in Qatar
(
Qatar University Press
, 2023 , Conference Paper)
Thermal cracks can occur in concrete elements at early stages during the hardening process. Also, the impact of thermal contraction and drying and autogenous shrinkage, may lead to excessive tensile strains and as a result ...
