( Qatar Univesrity Press , 2020 , Conference)The case of redesigning Souq Waqif station by raising the base slab formation level due to significant water inflow during the excavation and dewatering works and the break in activities of two EPB TBMs under adverse ... -
Water Supply from Turkey to Cyprus Island with Suspended Marine Pipeline
( Qatar Univesrity Press , 2020 , Conference)More than 90% of the water requirement for the Turkish Republic of Northern Cyprus (TRNC/KKTC) was being supplied from groundwater resources, while the rest was being provided from surface waters and seawater until the ... -
Utilizing Recycled Polypropylene Fibers as Reinforcement for Concrete Beams
( Qatar Univesrity Press , 2020 , Conference)Polypropylene (PP) fibers are among numerous plastic waste materials, which are generated by the different industrial and domestic activities. Due to its low biodegradability, plastic waste constitutes a real environmental ... -
Experimental Study on the Performance of Circular Concrete Columns Reinforced with GFRP under Axial Load
( Qatar Univesrity Press , 2020 , Conference)Corrosion of steel reinforcement in concrete structures subjected to severe environments is a big challenge and requires huge repair and maintenance costs. Glass fiber reinforced polymer (GFRP) reinforcement with its ... -
Structural Efficiency of Steel Stiffening Deck Systems in Suspension Bridges Due to Gravity Loads
( Qatar Univesrity Press , 2020 , Conference)In this paper, suspended stiffened decks in suspension bridges are considered. Three steel deck-stiffening systems are compared structurally; the plate girder, the box girder and the stiffening truss. A three-span ... -
Dosage Optimization of Polypropylene Fiber for Strength Enhancement of Cementitious Composites
( Qatar Univesrity Press , 2020 , Conference)"Concrete is the most commonly used materials for construction in Qatar as well as in the world. Exposure to sever environmental conditions causes physical deterioration of concrete structures and significantly affect ... -
Accelerated Corrosion Tests on Lapped Spliced Joints in Concrete
( Qatar Univesrity Press , 2020 , Conference)This paper presents a new test setup of experiments to investigate corrosion at lapped spliced joints using accelerated corrosion test. The experiments were carried out on two set of samples: cylinders and beam blocks. ... -
Reflective Crack Mitigation Using AST Interlayer over Soil-Cement Base for Flexible Pavements
( Qatar Univesrity Press , 2020 , Conference)Flexible pavement over soil-cement base deteriorates over time due to reflective cracking caused by the shrinkage of such base. The propagation of the reflective cracks in overlaying hot mix asphalt (HMA) could be mitigated ... -
Crowd Dynamics, Management and Control at Tourist Attractions during Special Events: A Case Study at Souq Waqif Using Pedestride® Crowd Simulation Tool
( Qatar Univesrity Press , 2020 , Conference)"Large crowds can be expected at famous tourist attractions, e.g., Souq Waqif, during special events such as the FIFA World Cup 2022. A comprehensive understanding of crowd dynamics is extremely important in order to ... -
An Innovative Structural Solution to Failed Stabilized Earth Embankment in Multilevel Interchange
( Qatar Univesrity Press , 2020 , Conference)This paper summarizes a case study of a failure in a mechanically stabilized earth retaining wall ramp heading to a multilevel interchange. The failure was caused by a washout cavity resulting from a long-term leakage from ... -
Integrated Accident Resilience Framework (IARF) – A Theoretical Approach Using Spatial and Statistical Analysis
( Qatar Univesrity Press , 2020 , Conference)Throughout the world, road accidents have become a nightmare for any local government. Data shows that every 24 seconds someone dies on the road (WHO, 2018). Generally, there are multiple factors causing road accidents ... -
Crowd Logistics Delivery Determinants: A Stated-Preference Survey
( Qatar Univesrity Press , 2020 , Conference)"the environment. Consumers’ attitudes toward CL are understudied, especially in Qatar, where CL is currently unavailable. The purpose of this paper is to investigate consumers’ reactions to the theoretical attributes ... -
Climate Change and the Structural Resilience of the Doha Metro
