A Markovian-Genetic Algorithm Model for Predicting Pavement Deterioratio
( Qatar University Press , 2023 , Conference)Pavement structures are constantly deteriorating due to many distresses, for instance cracks and rutting that are initiated and expanded. Deterioration models of pavement structures is an important component of pavement ... -
A Review on the Performance of Bored Pile Foundations through Instrumented Pile Load Tests in Qatar
( Qatar University Press , 2023 , Conference)The level of infrastructure development Qatar has accomplished over the past 10 years has not been reached by any other country and this pace is expected to continue to achieve Qatar's 2030 Vision. High-rise buildings and ... -
A Static and Free Vibration Analysis of Porous Functionally Graded Beams
( Qatar University Press , 2023 , Conference)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 ... -
ABAQUS Modelling and Experimental Tests Comparison for Certain Classes of Composite Isolated Joints
( Qatar University Press , 2023 , Conference)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)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 ... -
Analysis of Factors Affecting the Performance of Dynamic Compaction Technique: A Study of Coastal Area of Eastern Province in Saudi Arabia
( Qatar University Press , 2023 , Conference)Coastal areas of the Eastern Province of Saudi Arabia have soil with low bearing capacity due to saturation with water, high contents of salt and inclusion of organic materials. The dynamic compaction (DC) technique, which ... -
Ashghal Guidelines for the Evaluation and Repair of Sinkholes
( Qatar University Press , 2023 , Conference)Sinkholes are a common and recurring problem with potential safety risks to road users and authorities. A sinkhole is a void in the ground caused by natural and/or manmade activities, and mainly associated with carbonate ... -
