Mechanical characteristics of ultra-high performance steel FRC made with recycled concrete aggregates
( American Institute of Physics Inc. , 2023 , Conference Paper)Recycled concrete aggregates (RCA) are increasingly becoming a sustainable alternative to natural aggregate (NA) for concrete applications. This study, therefore, tests the influence of RCA on the fresh and hardened ... -
The Influence of Reinforcement Ratio on the Shear Behaviour of Sand Coated Basalt FRP Bars Reinforced Beams
( Springer Science and Business Media Deutschland GmbH , 2022 , Conference Paper)Qatar is known by its harsh corrosive environment that is represented by high periodical humidity, and dust accompanied by temperature fluctuation. Also, geographically Qatar is considered a peninsula, this in turn makes ... -
Characteristics of Concrete Made with Treated Domestic Wastewater
( Springer Science and Business Media Deutschland GmbH , 2022 , Conference Paper)The dramatic increase in the worldwide production of concrete and its consequences in depleting freshwater resources has become an urgent challenge among researchers. Many countries use the desalination treatment method ... -
Flexural Capacity of Sustainable RC Beams Manufactured with Treated Wastewater, RCA, and Fly Ash
( Springer Science and Business Media Deutschland GmbH , 2023 , Conference Paper)Sustainable concrete with recycled materials has recently received considerable interest among researchers. Of the available recycled materials, treated wastewater (TWW), recycled concrete aggregates (RCA), and fly ash ... -
Mechanical Characteristics and Durability of Concrete Made with Treated Domestic Wastewater and Recycled Concrete Aggregates
( East Carolina University , 2022 , Conference Paper)Massive amounts of fresh water and natural aggregates are annually used for concrete applications, resulting in a rapid depletion of freshwater and natural aggregate resources. This necessitates the need of replacing fresh ... -
Bond Strength of Basalt FRP Bars with Different Surface Treatments to Plain and Fiber-Reinforced Concrete
( Springer Science and Business Media Deutschland GmbH , 2023 , Conference Paper)The current study presents an investigation on the influence of the surface texture of the reinforcing bar and the addition of macro fibers to concrete on the bond strength of basalt fiber reinforced polymers (BFRP) bars. ... -
Flexural vibration attenuation properties of phononic crystals
( Trans Tech Publications Ltd , 2019 , Conference Paper)Phononic crystals (PCs) have the ability to have phononic bandgaps dependent on the acoustic properties of its constituent materials (i.e., mass, elasticity). Forming a 1D periodic variation using a viscoelastic material ... -
Experimental and numerical investigation of the flexural behavior of one-way RC slabs strengthened with near-surface mounted and externally bonded systems
( Elsevier , 2024 , Article)This study investigated the flexural performance of one-way reinforced concrete (RC) slabs strengthened with two distinct strengthening systems: near-surface mounted (NSM) bars and externally bonded (EB) carbon fiber-reinforced ... -
Flexural Behavior of Basalt Fiber-Reinforced Concrete Slab Strips with BFRP Bars: Experimental Testing and Numerical Simulation
( American Society of Civil Engineers (ASCE) , 2020 , Article)This study investigated the flexural behavior of a new one-way concrete slab system reinforced longitudinally with basalt fiber-reinforced polymer (BFRP) bars and cast with basalt fiber-reinforced concrete (BFRC). The study ... -
Evaluating prestress losses in a prestressed concrete girder railway bridge using distributed and discrete fibre optic sensors
( Elsevier , 2020 , Article)This paper evaluates the data collected during a comprehensive monitoring campaign aimed at capturing the prestress loss behaviour of four 11.9 m prestressed concrete beams. These beams formed part of the superstructure ... -
Simulation of axial tensile well deformation during reservoir compaction in offshore unconsolidated methane hydrate-bearing formation
( Elsevier , 2021 , Article)Sand production encountered in the 2013 offshore field gas production tests at the Nankai Trough, Japan, could be attributed to well failure during reservoir compaction. In this study, well integrity under various reservoir ... -
Monitoring of shaft excavations in clay
( ICE Publishing , 2019 , Conference Paper)Field observations of infrastructure performance, during and following construction, are vital for efficient design of infrastructure in subsequent projects. Fibre optic sensing technology offers considerable benefits ... -
Pile defect assessment using distributed temperature sensing: fundamental questions examined
( SAGE Publications Ltd , 2024 , Article)Thermal integrity testing has been successfully used to assess the quality of cast-in-place piles for the past decade. It employs temperature data measured during concrete curing to identify defects along the piles' length. ... -
Real-time statistical modelling of data generated from self-sensing bridges
( ICE Publishing , 2018 , Article)Instrumentation of infrastructure is changing the way engineers design, construct, monitor and maintain structures such as roads, bridges and underground structures. Data gathered from these instruments have changed the ... -
Introducing data-centric engineering to instrumented infrastructure
( ICE Publishing , 2019 , Conference Paper)A variety of methods exist in the structural health monitoring literature that aim to combine the observed data and predicted outputs from physics-based models (e.g. model updating and calibration). Typically implemented ... -
A systematic review of machine learning classification methodologies for modelling passenger mode choice
( Elsevier , 2021 , Article Review)Machine Learning (ML) approaches are increasingly being investigated as an alternative to Random Utility Models (RUMs) for modelling passenger mode choice. These approaches have the potential to provide valuable insights ... -
Back-analysis of sprayed concrete lined (SCL) tunnel junctions at Liverpool Street Crossrail station
( Elsevier , 2023 , Article)Sprayed concrete linings (SCL) offer a versatile method of tunnel construction, particularly in regard to forming junctions since the lining acts as a shell structure which can redistribute the stresses around the opening ... -
Experimental and numerical investigation of the performance of self-sensing concrete sleepers
( SAGE Publications Ltd , 2020 , Article)Prestressed concrete sleepers with built-in fibre optic-based sensing systems have recently been developed to capture performance data within railway networks and to provide critical decision-support information to route ... -
Arching in granular soils: Experimental observations of deformation mechanisms
( ICE Publishing , 2021 , Article)Understanding soil arching is an important component of predicting soil behaviour in cases such as the progressive displacements above sinkholes and when predicting loads on buried structures, where the expected deformation ... -
Arching in granular soils: Limit state equilibrium
( ICE Publishing , 2021 , Article)One of the most critical assumptions in the application of arching theory is an accurate estimate of the coefficient of lateral stress, K, used to relate vertical and horizontal stresses on the assumed failure plane. ...
