Purpose – The potential threats of extreme events to highway bridges have received increased attention from government agencies, the engineering and construction communities, and the traveling public. These events include terrorist attacks as well as human-induced and natural hazards such as earthquakes, explosions, fires, floods, and hurricanes. To respond to the potential threats on highway b...

My research focuses on understanding the interactions and dynamics between crop systems and soil microbiomes in both natural and engineered systems. My overarching goal is to bridge the gap between biotechnology, agriculture, and engineering in order to understand how rhizospheres are affected by both soil chemistry and exposure to emerging contaminants of concern, with the ultimate goal of man...

Many established techniques and modeling methods for business process management (BPM) are known. Since many of them are domain-independent, they can also be applied for requirements engineering within software development processes. In order to build a bridge between requirements engineering and the BPM body of knowledge, this paper first identifies 26 basic process characteristics (e.g., dura...

Grid computing technology is a focused field in high performance computing. This paper describes an engineering computation oriented visual grid framework VGrid, which is capable to bridge the gap between currently deployed grid services and the computational applications. Based on the Globus toolkit, and coupled with a client component, a services pool and a server component, VGrid visually pe...

The Bay Bridge is a high performance bridge/router capable of bridging and routing over 100,000 packets per second between two network ports. The first prototype provides a platform for the investigation of very high speed bridging and routing in hardware. High throughput is achieved by a specialised processor: The Protocol Converter, a programmable device for translating between network protoc...

For concrete bridge projects in marine environments, attention must be paid to the reinforcement corrosion problems caused by chloride intrusion. As kinds of functional admixtures, which can reduce the reinforcement corrosion rate, corrosion inhibitors are becoming very popular in China in new bridge projects. Corrosion inhibitors cover both inorganic and organic inhibitors. Nitrite is represen...

Many long-span bridges have been built throughout the world in recent years but they are often subject to multiple types of dynamic loads, especially those located in wind-prone regions and carrying both trains and road vehicles. To ensure the safety and functionality of these bridges, dynamic responses of long-span bridges are often required for bridge assessment. Given that there are several ...

This paper presents a case study of geotechnical design of bridge foundations and approaches in hilly granite formation in northern New South Wales of Australia. Firstly, the geological formation and existing cut slope conditions which have high risks of rock fall will be described. The bridge has three spans to be constructed using balanced cantilever method with a middle span of 150 m. After ...

IFC (Industry Foundation Classes) is the commonly accepted data exchange standard for Building Information Models (BIM). However, the geometric representation in IFC is restricted to explicit, extrusion and CSG (Constructive Solid Geometry) approaches. Accordingly, the exchange of parametric geometry between parametric design applications used in the AEC (Architecture, Engineering and Construct...
