ONE OF THE key issues in the design and construction of any gas pipeline is the prevention of material fracture. Since the gas is generally transported under high operating pressures, it must be ensured that the gas pipeline is sufficiently tough to arrest the propagation of any potential fracture. For several decades, control of gas pipeline fracture propagation has been under scrutiny due to economic considerations and ecological and safety hazards related to pressurised pipe failure. The Battelle Two Curve approach has been widely used to determine the minimum material arrest toughness by comparing the gas decompression wave velocity with ...

Asset Management In The Energy Pipeline Industry In Australia, Richard Dwight, Tieling Zhang, Khaled O. El-Akruti

Faculty of Engineering and Information Sciences - Papers: Part A

A review of asset management systems within the context of energy pipelines has been conducted. It covers available methodologies, current asset management systems, opportunities for improvement and research challenges. A particular point of interest is the degree to which consideration of remaining life and the influence of maintenance activities are used to drive the asset management strategy. Asset management within the energy pipeline industry is mostly concerned with integrity assurance. Irrespective of this overriding goal, cost of delivery is also of concern. At any point of the service life the remaining life of the pipeline at an acceptable level of ...

Operations Strategy Processes: How Significant Are They?, Senevi Kiridena, Kalinga Jagoda, Howard Lin

Faculty of Engineering and Information Sciences - Papers: Part A

Ongoing challenges associated with the implementation of formally developed strategies call for studying the functional level strategy processes from fresh perspectives. This paper presents evidence drawn from the Canadian oil and gas industry towards establishing the statistical significance of alternative operations strategy processes and organisational contextual factors. The analysis discerned four strategy process configurations representing singular and multiple combinations of three strategy process modes identified in previous qualitative studies. The findings will help advance the understanding of operations strategy processes and may contribute to theory building, as the evidence was drawn from a relatively large sample of data representing an ...

Agency In Transport Service: Implications Of Traveller Mode Choice Objective And Latent Attributes Using Random Parameter Logit Model, Ahm Mehbub Anwar, A Kiet Tieu, Peter Gibson, Khin Than Win, Matthew J. Berryman

Faculty of Engineering and Information Sciences - Papers: Part A

This paper explains how principal-agent theory (PAT) can be used as an analytical tool to understand the traveller-Transport for NSW relationship and minimise the agency uncertainty in the relationship by examining traveller preferences for mode choices. The paper emphasises latent variables and objective attributes together during the choice process within the agency relationship, as a method by which the utility of the principal (traveller) can be maximised and evaluated using a discrete choice experiment, i.e. random parameter logit (RPL) model. The probability of car useis significantly higher than public transport, which indicates that an agency uncertainty exists in the ...

The Tunable Wettability In Multistimuli-Responsive Smart Graphene Surfaces, Shanhong Wan, Jibin Pu, Xiaoqian Zhang, Liping Wang, Qunji Xue

Faculty of Engineering and Information Sciences - Papers: Part A

The tunable wettability of smart graphene films onto stainless steel substrates with a multi-response to different environmental stimuli has been investigated including light irradiation, pH, electric field, and annealing temperature. Conductive graphene film exhibited the controllable transition from water-repellent to water-loving characteristic in response to different environment fields, which primarily resulted from the morpho-chemically synergistic effect as well as the restoration of electronic stucture. Based on the fundamental theories of wettability, mechanisms in switching from hydrophobicity to hydrophilicity for smart graphene surface including thermal chemistry, electrostatic, photo-induced surface chemistry, solvent, and pH methods were presented.


Numerical Study On Interaction Between Steel Stirrups And Shear- Strengthening Nsm Frp Strips In Rc Beams, G M. Chen, S W. Li, S S. Zhang, J F. Chen, J G. Teng Jan 2013

Numerical Study On Interaction Between Steel Stirrups And Shear- Strengthening Nsm Frp Strips In Rc Beams, G M. Chen, S W. Li, S S. Zhang, J F. Chen, J G. Teng

Faculty of Engineering and Information Sciences - Papers: Part A

RC beams shear-strengthened with externally bonded or near-surface mounted (NSM) FRP reinforcement usually fail by the debonding of FRP in a brittle manner. When the FRP reinforcement debonds, the internal steel stirrups may have not reached their yield strength, so the contribution of the latter to the shear resistance of the beam is compromised to some extent. This phenomenon is referred to as the adverse shear interaction between the steel stirrups and the bonded FRP shear reinforcement. This paper examines such shear interaction in RC beams shear strengthened with NSM FRP strips using a simple computational model. Numerical results obtained ...


Simplified Finite Element Modelling Of End Cover Separation In Rc Beams Flexurally-Strengthened With Bonded Frp Reinforcement, S S. Zhang, J G. Teng Jan 2013

Simplified Finite Element Modelling Of End Cover Separation In Rc Beams Flexurally-Strengthened With Bonded Frp Reinforcement, S S. Zhang, J G. Teng

Faculty of Engineering and Information Sciences - Papers: Part A

The flexural performance of RC beams can be improved using externally bonded (EB) or near-surface mounted (NSM) fibre-reinforced polymer (FRP) reinforcement. One of the commonly observed failure modes of such FRP-strengthened RC beams is the end cover separation failure mode which involves the detachment of the bonded FRP reinforcement together with the cover concrete along the level of the longitudinal steel reinforcement. This paper presents a simplified finite element (FE) model for end cover separation failure in RC beams flexurally-strengthened with either EB or NSM FRP. In this simplified FE model, only the part of the RC beam between the ...


Seismic Retrofit Of Rc Frames Through Beam-End Weakening In Conjunction With Frp Strengthening, J G. Teng, S S. Zhang, D H. Jing, X F. Nie, G M. Chen Jan 2013

Seismic Retrofit Of Rc Frames Through Beam-End Weakening In Conjunction With Frp Strengthening, J G. Teng, S S. Zhang, D H. Jing, X F. Nie, G M. Chen

Faculty of Engineering and Information Sciences - Papers: Part A

The strong column/weak beam requirement is now widely accepted in the design of reinforced concrete (RC) frames to achieve good seismic performance. However, many existing RC frames violate this requirement as they were designed according to inadequate design codes (generally previous codes). In particular, RC frames designed according to the previous Chinese codes for seismic design are likely to violate this requirement as the contribution of a cast-in-place floor slab in tension is not included in assessing the moment capacity of the beam in negative bending. This paper proposes three promising beam weakening techniques in combination with FRP strengthening ...


Bond-Slip Model For Interfaces Between Near-Surface Mounted Cfrp Strips And Concrete, S S. Zhang, J G. Teng, T Yu Jan 2013

Bond-Slip Model For Interfaces Between Near-Surface Mounted Cfrp Strips And Concrete, S S. Zhang, J G. Teng, T Yu

Faculty of Engineering and Information Sciences - Papers: Part A

This paper presents a bond-slip model for interfaces between near-surface mounted (NSM) CFRP strips and concrete where debonding occurs due to cohesion failure in the concrete adjacent to the CFRP strip. This bond-slip model was derived on the basis of numerical results from a parametric study conducted using a verified 3-D meso-scale finite element (FE) model. In the proposed bond-slip model, the concrete compressive strength and the groove height-to-width ratio are the two main parameters: the former indicates how strong the concrete itself is while the latter represents the level of confinement provided by the surrounding concrete to the bonded ...

A Note On Asymptotic Exponential Arbitrage With Exponentially Decaying Failure Probability, Kai Du, Ariel Neufeld Jan 2013

A Note On Asymptotic Exponential Arbitrage With Exponentially Decaying Failure Probability, Kai Du, Ariel Neufeld

Faculty of Engineering and Information Sciences - Papers: Part A

The goal of this paper is to prove a result conjectured in Follmer and Schachermayer (2007) in a slightly more general form. Suppose that S is a continuous semimartingale and satisfies a large deviations estimate; this is a particular growth condition on the mean-variance tradeoff process of S. We show that S then allows asymptotic exponential arbitrage wiith exponentially decaying failure probability, which is a strong and quantitative form of long-term arbitrage. In contrast to Follmer and Schachermayer (2007), our result does not assume that S is a diffusion, nor does it need any ergodicity assumption.

On The Residual Energy Toughness Of Prestressed Concrete Sleepers In Railway Track Structures Subjected To Repeated Impact Loads, Sakdirat Kaewunruen, Alexander Remennikov

Faculty of Engineering and Information Sciences - Papers: Part A

Installed as the crosstie beam support in railway track systems, the prestressed concrete sleepers (or railroad ties) are designed in order to carry and transfer the wheel loads from the rails to the ground. It is nowadays best known that railway tracks are subject to the impact loading conditions, which are attributable to the train operations with either wheel or rail abnormalities such as flat wheels, dipped rails, etc. These loads are of very high magnitude but short duration, as well as there exists the potential of repeated load experience during the design life of the prestressed concrete sleepers. These ...
