Discrete Element Modeling Of Railroad Ballast Under Simulated Train Loading
(2019 , Master Thesis)Ballasted tracks have been widely used in many countries around the world. Ballast layer is the main element in ballasted track. After service, ballast aggregates degrade and deform. Periodical maintenance for ballast ... -
OPERATIONAL MODEL ANALYSIS AND FINITE ELEMENT MODEL UPDATE USING AMBIENT VIBRATION DATA FOR AL-SINYAR TOWER
(2018 , Master Thesis)Buildings in Qatar rely on minimum structural code requirements implemented by design consultants’ offices. Qatar 2030 vision considers increasing of structures’ sustainability and serviceability as a high priority, which ... -
An Investigation Of Vibration From Underground Tunnels By Using A Plane-Strain Finite Element Model
(2018 , Master Thesis)In 2013, Qatar Rail announced major rail projects that include an urban rail network for the city of Doha with lines running on the surface and underground which are expected to be in operation by 2020. Railway systems are ... -
Evaluation Of The Main Factors Affecting Tire-Pavement Interaction Noise
(2018 , Master Thesis)Traffic noise is an environmental pollution that affects many people in today’s modernized world. It disrupts the quality of life and causes annoyance, stress, sleep deprivation, and several health problems. When vehicles ... -
Shear Behavior Of Fiber Reinforced Concrete Beams Reinforced With Basalt Frp Bars And Gfrp Stirrups
(2018 , Master Thesis)Qatar suffers from a harsh environment in the form of high temperature that prevails almost all year round in addition to severe humidity and coastal conditions. This exposure leads to the rapid deterioration and the ... -
Factors Affecting Bus Ridership In Qatar
(2018 , Master Thesis)Traffic congestion is a major problem in Qatar where most of the population are car dependent. The purpose of this study is to understand the influence of various attributes on the system wide and stop level of public buses ... -
STRENGTHENING OF SHEAR DEFICIENT REINFORCED CONCRETE BEAMS USING NEAR SURFACE EMBEDDED FABRIC REINFORCED CEMENTITIOUS MATRIX
(2018 , Master Thesis)This thesis presents an experimental study on the efficacy of new concepts of strengthening reinforced concrete beams deficient in shear. The first concept is referred to as “near surface embedded” fabric reinforced ... -
Characteristics of Parallel On-Street Parking in Qatar
(2018 , Master Thesis)One of the main reasons for traffic congestion is the existence of on-street parking on the side of the road. The purpose of this study is to identify the impact of parallel on-street parking on the traffic flow movement ... -
Strengthening of reinforced concrete beams With Textile- Reinforced mortars
(2016 , Master Thesis)This study involves an experimental work for using textile reinforced mortar (TRM) to increase the flexural strength of reinforced concrete (RC) beams. Two different types of textiles namely carbon and Polyparaphenylene ... -
Condition Assessment Models for Sewer Pipelines
(2017 , Master Thesis)Underground pipeline system is a complex infrastructure system that has significant impact on social, environmental and economic aspects. Sewer pipeline networks are considered to be an extremely expensive asset. This study ... -
Flexural Behavior of Basalt Fiber Reinforced Concrete Beams with Recycled Concrete Coarse Aggregates
(2017 , Master Thesis)The State of Qatar has experienced tremendous economic development in the last decades. As a result, massive quantities of building materials have been used to accommodate the great pace in construction. However, Qatar ... -
Investigation of Gap Acceptance at Roundabouts in Qatar
(2017 , Master Thesis)Modern roundabouts are a popular method to control traffic at intersections. In this type of roundabouts, priority is given to the circulating flow, and the approaching vehicles have to find a gap to merge with the flow ... -
Automated Defect Detection Tool For Sewer Pipelines
(2017 , Master Thesis)In sewer networks, the economic effects and costs that result from a pipeline break are rising sharply. In Qatar, majority of the sewer network pipelines were installed in the last 20 years and are currently in poor condition ... -
A NON-DESTRUCTIVE METHODOLOGY FOR LEAK DETECTION IN WATER NETWORKS USING INFRARED PHOTOGRAPHY (IR) AND GROUND PENETRATING RADAR (GPR)
(2016 , Master Thesis)Two noninvasive and nondestructive methodologies for detecting leaks in water pipes were proposed and tested. The first method combines the use of Ground Penetrating Radar (GPR) for accurate determination of pipe location, ... -
Drained residual shear strength of fine-grained soils and soil-solid interfaces at low to medium effective normal stresses: Analyses and Applications
(2016 , Master Thesis)A laboratory research program was undertaken to study the large-strain shear strength characteristics of fine-grained soils under low effective normal stresses (~3 to 6 kPa). Soils that cover a wide range of plasticity and ...
