This paper describes a model-based system and software development process that combines both function-driven systems engineering and object oriented software engineering. The key part of this "Integrated Process" is the "Bridge" between the two paradigms. Tools chosen to demonstrate the Integrated Process are the I-Logix tools Statemate Magnum, for the function-driven systems engineering, and...

Progressive collapses of arch bridges have repeatedly occurred in recent years, resulting in many casualties and significant property losses. Based on an actual recent and serious progressive collapse of a stone arch bridge, this paper simulated the complete progressive-collapse process using the general purpose finite element (FE) program, MSC.Marc. The simulation adopted a 3D FE model and per...

Prediction of bridge pier scour depth is essential for safe and economical bridge design. Keeping in mind the complex nature of bridge scour phenomenon, there is a need to properly address the methods and techniques used to predict bridge pier scour. Up to the present, extensive research has been carried out for pier scour depth prediction. Different modeling techniques have been applied to ach...

Engineers have long relied on public feedback of engineering failures to improve their designs. Consider the result if bridge builders had ignored the lessons learned from the torsional oscillations that caused the Tacoma Narrows Bridge to collapse. Consider the result if ship builders had ignored the lessons learned from the inadequate lifeboat space and manning that allowed the great loss of ...

1 Abhijit Nagchaudhuri, University of Maryland Eastern Shore, Princess Anne, MD. 21853-1299, [email protected] Abstract –. The burgeoning field of “Mechatronics” has been evolving over the last few decades as a new field of pedagogy within the engineering curricula. “Mechtatonics” synergistically combines engineering mechanics, electronics, and computer technology. The development may...

A new generation of concrete highway bridges has recently been built in Canada using new design concepts and advanced materials for reinforcing and prestressing concrete . This paper describes briefly the design and construction of three bridges. The first smart concrete highway bridge (Centre Street, Beddington Bridge, Calgary, Alberta) is prestressed by carbon fiber reinforced plastic (CFRP) ...

Recently, an increase in the number of construction of long span bridges like a cable-stayed bridge has necessitated the development of technologies for long-term maintenance works and safety of vehicles using such bridges. A lot of researches on application of cutting-edge IT technologies and robotics in the civil engineering field have been conducted for better operation and maintenance of a ...

Infrastructures are a key factor for economy. Among them, transportation infrastructures are vital for human life and economy. And within the transportation networks, bridges are key elements for connecting people anddelivering goods. For this reason, bridges have been built sincemany centuries ago, in some way, and the advances (and sometimes geographical expansions!!) of ancient cultures all ...
