Major Factors

Bridge health monitoring is increasingly relevant for the maintenance of existing structures or new structures with innovative concepts that require validation of design predictions. In the United States there are more than 600,000 highway bridges. Nearly half of them (46.4%) are rated as fair while about 1 out of 13 (7.6%) is rated in poor condition. As such, the United States is one of those countries in which bridge health monitoring systems are installed in order to complement conventional periodic nondestructive inspections. This paper reviews the challenges associated with bridge health monitoring related to the detection of specific bridge characteristics that may be indicators of anomalous behavior. The methods used to detect loss of stiffness, time-dependent and temperature-dependent deformations, fatigue, corrosion, and scour are discussed. Owing to the extent of the existing scientific literature, this review focuses on systems installed in U.S. bridges over the last 20 years. These are all major factors that contribute to long-term degradation of bridges. Issues related to wireless sensor drifts are discussed as well. The scope of the paper is to help newcomers, practitioners, and researchers at navigating the many methodologies that have been proposed and developed in order to identify damage using data collected from sensors installed in real structures.

Design And Construction

Although cycloidal propulsion is well known and has been widely accepted in European service for many years, its applications in the United States are relatively rare. The reasons for selecting this unique propulsion concept for the two new ferries now under construction for Manhattan-Staten Island service are described in this paper, as well as the design and construction problems encountered.

Near Future

<p>Compared to conventional structural grade steels, high-performance steel (HPS) pro­vides higher strength, improved weldability, greatly enhanced fracture toughness, and comparable ductility, as well as having "weathering" properties. The improved char­acteristics of HPS are achieved through lower levels of carbon and other elements, in conjunction with advanced steel-making practices using either quenching and tem­pering or thermo-mechanical controlled processing. All of these properties make HPS highly desirable for bridge applications. Indeed, although its development spans only the past decade, it is rapidly gaining popularity for use in highway bridges and is be­coming more widely available. Although many highway bridges have already been put into service in the United States, Canada has yet to implement this technology in bridges. Nevertheless, it is anticipated that the use ofHPS will become common in the Canadian market in the near future.</p>

This paper presents the state of the practice of the use of cable barrier systems in the United States. A literature review was conducted to identify the types of cable barriers systems being used. The scope of this review included benefits of using cable barriers, available guidelines, policies or procedures related to barrier placement, and issues related to the maintenance and in-service performance of the cable barriers. A comprehensive survey was conducted to identify experiences, practices, and design and construction standards for the use of cable barrier systems. To improve survey quality, survey participants were people identified as managing the cable barrier systems firsthand. The participants were therefore likely to be most knowledgeable about the design and construction, maintenance, and overall experience of cable barrier usage. Concluding remarks about the state of the practice of cable barriers, along with areas of further research, are presented.

Year 2000

The first seismically isolated building in the United States was completed in 1985. In the fourteen years since then, a total of not more that twenty-five new buildings and twenty-two retrofits of existing buildings hass been completed. In constrast, the number of base-isolated building in Japan completed over the same time period is of the order of a few hundred, and in China, where the first isloated building was completed in 1995, there are now over seventy base-isolated building.Currently there are several building codes that govern the desing of base-isolated buildings in the United States. New regulations have been prepared for the year 2000 and beyond, which are both complex and conservative, discouraging the use of seismic isolation. These codes require the engineer to desing isolators for very large displacements and mandate extensive prototype and production testing, thereby restricting isolation's application to special structures such as hospitals and emergency service centers where a requirement for operational functionality following large earthquake events justifies the cost premium and time delays associated with the use of seismic isolation.Conversely, seismic isolation is widely used throughout the United States for highway bridges and is governed by a single desing code that is simple tob use and not overly conservative. Isolation systems are being used for the retrofit of several very large bridges in California. The isolators to be used for this projects are very large, and a test machine at the University of California, San Diego (UCSD), has just been completed to test these Isolators at full-scale, real-time rates.This paper will describe the current regulatory evironment for seismic isolation and the testing requirements for isolators. A description of the new test facility at UCSD will be included.
