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. ... -
Applicability of construction dewatering techniques for randomly-fractured rock
( ICE Publishing , 2024 , Article)Through analyzing a significant number of case histories, ranges of applications of dewatering techniques for randomly-fractured rock are proposed in terms of the rock mass permeability and the required drawdown. The ... -
Measurement of pile uplift forces due to soil heave in expansive clays
( Canadian Science Publishing , 2022 , Article)Piled foundations are widely used to limit the movement of foundations in expansive clays. These piles are subjected to large uplift forces as the clay swells (and downdrag forces when it shrinks). The appropriate method ... -
Short-term and long-term behavior of RC beams strengthened by galvanized steel mesh laminate
( Elsevier , 2022 , Article)Steel reinforced polymers (SRP) are useful in a wide range of applications, including strengthening of existing reinforced concrete (RC) structures, due to their numerous advantages like high strength, low maintenance, ... -
Integrity monitoring of cast in-situ piles using thermal approach: A field case study
