The Florida Pier Analysis Program (FLPIER) was developed by the University of Florida Department of Civil Engineering in conjunction with the Florida Department of Transportation (FDOT) Structures Division. The program was developed in order to give pier designers a comprehensive model development and analysis tool to optimize pier designs. The current version is a nonlinear, static, soil-structure interaction suite of programs that run on a personal computer and include group pile effects, layered soil, pier columns and cap, high mast lighting, sound, and retaining walls. The program was designed to allow input to be specified graphically using “designer variables” such as spacing, offsets, number of columns, and so forth. Its use has reduced the time for model development and analysis from days to under an hour. The numerical modeling techniques used have been compared with experimental data and give highly accurate results leading to an improved overall design and reduced costs.

The new 2002 AASHTO guide for the design of pavement structures is based on mechanistic principles and requires the dynamic modulus as input to compute stress, strain, and rutting and cracking damage in flexible pavements. The 2002 AASHTO guide has three different levels of analysis; the level used depends on the importance of the pavement structure in question. Dynamic modulus testing is required for Level 1 pavement analysis, whereas no laboratory test data are required for Level 2 and Level 3 pavement analysis. Instead, a predictive dynamic modulus equation is used to generate input values. It is of significant importance to state agencies to understand how well the dynamic modulus for locally available materials compares with the predicted dynamic modulus. This paper presents the results of a study by the Florida Department of Transportation and the University of Florida that focused on the evaluation of the dynamic modulus predictive equation used in the new AASHTO 2002 guide for mixtures typical to Florida. The resulting research program consisted of dynamic modulus testing of 28 mixtures common to Florida. Results showed that on average the predictive modulus equation used in the new AASHTO 2002 flexible pavement design guide appeared to work well for Florida mixtures when used with a multiplier to account for the uniqueness of local mixtures. Results of the study also identified optimal viscosity–temperature relationships that result in the closest correspondence between measured and predicted dynamic modulus values.

The Florida Legislature passed a law in 1971 requiring the establishment of coastal construction setback lines on a county basis along the sand beaches of the State of Florida fronting on the Atlantic Ocean and the Gulf of Mexico. Florida's beach areas (valued in $ billions) are being developed at an accelerated rate, however the coastline is in a general state of serious erosion. These factors combine to make implementation of the above law extremely urgent. The Coastal and Oceanographic Department of the University of Florida has a contract with the Florida Department of Natural Resources to furnish a comprehensive engineering study of the various coastal counties of Florida in order to provide the technical information and make recommendations for the establishment of such setback lines. A typical coastal county study is described. The study included historical data related to shoreline stability, field measurements, computations and evaluation of all pertinent factors. Some factors considered were dune elevations, foreshore-offshore slopes, erosion trends, storm surge, vegetation bluff line, wave setup, uprush, coastal structures and upland development. Analysis of the pertinent factors resulted in formulation of criteria that were applied in recommendation of the setback line. The criteria application is described along with adoption procedures as required by law.

Brief descriptions are provided of a new cost-effectiveness analysis program, known as the Roadside Safety Analysis Program (RSAP), which was developed under NCHRP Project 22-9. RSAP is an improvement over existing cost-effectiveness analysis procedures for evaluation of roadside safety improvements, such as the procedures in the 1977 AASHTO barrier guide and the ROADSIDE program. RSAP improves on many of the algorithms in the procedures and provides a user-friendly interface to facilitate use. The program has undergone extensive testing and validation, including evaluation by an independent reviewer. It is anticipated that RSAP will be available to the public through the McTrans Center at the University of Florida.

From the toll plaza on the Oakland shores through the approach structures in San Francisco, the San Francisco—Oakland Bay Bridge, built at a cost of $78,000,000 in 1937, is an engineering marvel that carries over a quarter-million vehicles per day. Because of the different segments of the bridge and their inherent vulnerabilities, retrofitting was assigned to several groups within the California Department of Transportation. Briefly described are the analysis and design of the seismic retrofit of the West Crossing, which spans San Francisco Bay between the city of San Francisco and Yerba Buena Island. From the outset of this project, the goal was to keep the bridge in service following a magnitude 8.0 earthquake from the nearby San Andreas fault. Included in this discussion is a summary of analytical and engineering procedures used to model the seismic behavior and the performance of this complex, important structure. In addition there is some insight into the various levels of analysis that were utilized so that the project-specific performance-based design criteria could be met. Furthermore, there is discussion of how energy dissipation through foundation rocking and the use of viscous dampening devices made the overall design objective obtainable. Finally, there is some discussion on the retrofit details used to ensure compliance with the design criteria.

A full-scale field demonstration project consisting of installation, instrumentation, testing, and extraction of augered cast-in-place (ACIP) piles located in central Florida was undertaken in conjunction with the Florida Department of Transportation and the University of South Florida. Seven instrumented ACIP piles, with a nominal diameter of 457 mm (18 in) or 610 mm (24 in), were installed in mainly sand and silty sand. Load testing was performed on six ACIP piles: two in compression, two in tension, and two laterally. In addition, one of the ACIP piles was extracted for visual inspection and comparison to predictions and measurements. The program demonstrated the fully monitored installation and load tested performance of instrumented ACIP piles, along with the use of manual and automated monitoring; use and accuracy of embedded instrumentation, including thermal integrity profiling (TIP) and embedded strain gages; load-displacement behavior of tested ACIP piles; and the integrity and as-constructed geometry of an exhumed ACIP pile. This paper presents the details, results from the different testing performed, and observations from the experimental field program.

The University of Florida Department of Mechanical and Aerospace Engineering recently created a new senior technical elective in the field of computational fluid dynamics. The main objectives of the class are learning the process of computational fluid dynamics, skepticism, a course project that uses a popular commercial solver, and a course project that involves programming a simplified computational fluid dynamics code. The course covers introductory material, history, grid generation, numerics, equations of motion, boundary conditions, solvers, turbulence models, visualization, and a number of special topics. Skepticism is enforced throughout the course and forces students to justify the validity of their approach and question numerically generated results. Students in the class undertake a course project to predict a fundamental flow-field and compare predictions with excellent measurements from the open literature. They must also create a simplified computational fluid dynamics code to predict turbulent boundary layer flow. Students have integrated these lessons within student groups across the University of Florida. The emphasis of the course is on skepticism and increasing integration with the curriculum and student group activities. We present the class philosophy for teaching undergraduate computational fluid dynamics and the outcomes of the newly developed course.
