Charles Bridge in Prague is one of the most famous monuments of the European architectural heritage. As typical of complex historical structures, a realistic quantitative computational assessment of the bridge response should address multi-physics, multi-scale, time-dependent and three-dimensional aspects of the problem. In this paper, an example of such a study is reported. To keep the model c...

Probabilistic system-reliability methods have the potential to assist designers in better understanding the ultimate global behavior of bridges, thus leading to more economical, rational, and reliable structures. Nonetheless, these techniques are not currently broadly used in North American bridge engineering practice. Using a sample cable-stayed bridge design, a study is conducted to assess th...

Stimulated by the excessive deflections and collapse of the KB Bridge of world-rercord span, the deflection histories of 56 similar bridges, most of them excessive, have been collected by RILEM TC-MDC. They amount to a wake-up call: The standard creep recommendations of engineering societies have been misleading, and thus their revision is imperative. They also confirm a simple feature: The mul...

A brief history of developments in the field of low-speed aeroelasticity is provided in the context of application to long-span bridge structures. The paper begins with summary of some of the significant developments in aeroelasticity for low-speed aeronautical applications in the early 20th century. The role of the pivotal Tacoma Narrows failure and subsequent investigation is introduced. The ...

An advanced video deflectometer using actively illuminated LED targets is proposed for remote, real-time measurement of bridge deflection. The system configuration, fundamental principles, and measuring procedures of the video deflectometer are first described. To address the challenge of remote and accurate deflection measurement of large engineering structures without being affected by ambien...

This position paper describes our work with a new course at Sussex University, designed to bridge the gap between computer science and software engineering. We argue that the way in which software engineering is introduced in most computer science degrees makes it hard for students to internalise the lessons of good engineering practice. In particular, programming is seen to be divorced from so...

I Software Engineering II 1 Engineering, as it is properly understood, is not possible for software. An engineer can design a bridge, confident that it will meet its requirements when built. Our theory and tools are not yet good enough to let us build software to this standard of reliability. This course has less ambitious goals. It introduces methods for designing software systematically. It a...

The importance of integrating software engineering methods with HCI has been recognised for many years. Agile development is a new approach to software engineering that explicitly champions user involvement in the development process and presents a unique opportunity to bridge this gap. The agile manifesto specifically values customer collaboration, and eXtreme Programming (XP), probably the mo...

this paper presents a new bridge management system (j-bms). it is integrated with a concrete bridge rating expert system that can be used to evaluate the serviceability of existing concrete bridges. the proposed j-bms not only evaluates the performance of bridges, but also offers a rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. in this ...
