Based on the long-term monitored strain data induced by heavy vehicle traffic on an existing bridge, this paper presents an efficient approach to assessing the bridge system performance through a series-parallel system model consisting of bridge component reliabilities. The correlations among the bridge component safety margins are obtained by using actual traffic and strain data from structura...

Significant damage of transportation infrastructure systems usually occurs during a major earthquake event. The impacts of bridge damage include not only short-term costs of structural repair, but also long-term economic consequences. In addition to initial replacement or repair costs of damage to the transportation structures, large earthquakes increase delays because of network components sev...

While software systems are increasingly developed by using model-based techniques, requirements engineering is most still performed text-based. Requirements are generally structured using text-patterns or linked outlines; as a consequence, only an indirect, weakly structured transition to design is possible. Model-based requirements engineering offers a solution to bridge this gap. Essential ch...

A goal of the Studio course in the Master of Software Engineering program at Carnegie Mellon University is to bridge the gap between experience and academics. One way to transfer experience to young software engineers is through case studies designed to focus students on speci c software engineering problems. This paper discusses my experience with developing a case study to improve a student's...

three unconventional details for plastic hinges of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span reinforced concrete bridge. shape memory alloys (sma), special engineered cementitious composites (ecc), elastomeric pads embedded into columns, and post-tensioning were used in three different piers. the bridge model was subjected to...

Biomimetics contributes to innovative engineering by imitating the models, systems, and elements of nature. For biomimetics research, it is important to develop biomimetics database including widely varied knowledge across different domains such as biology and engineering. Interoperability of knowledge among those domains is necessary to create such a database. For this purpose, the authors are...

In 1972, J.T.P. Yao introduced the modern control theory into vibration control of civil structures (Yao, 1972), which started the new era of research on structural active control in civil engineering field. During the development of nearly 40 years, Active Mass Driver/Damper (AMD) control, with the better control effect and cheaper control cost, has taken the lead in various active control occ...

A key phase in the bridge design process is the selection of the structural system. Due to budget and time constraints, engineers typically rely on engineering judgment and prior experience when selecting a structural system, often considering a limited range of design alternatives. The objective of this study was to explore the suitability of supervised machine learning as a preliminary design...
