The University of Florida, Department of Civil Engineering developed Florida Pier (FLPIER) in conjunction with the Florida Department of Transportation (FDOT), Structures Division. The first official release of the program was version 5.23 in January 1996. A new release (version NT 1.15) is now available which includes many enhancements including mixed prestressing and mild steel reinforcement, nonlinear pier columns and cap, tapered pier columns and cap, equivalent linear stiffness matrix generation and many other features. In addition, the new release is a Windows NT/95 based program including the graphics portions. The program is capable of analyzing an entire bridge substructure (piles, cap and pier) in conjunction with its soil support resulting in a nonlinear coupled foundation analysis. The new release is a step closer to a complete design program, allowing engineers to optimize their structures. The program was designed to allow input to be specified graphically using "designer" variables such as pile spacing, column offsets, number of columns, batter, missing piles and more. The program is distributed freely by the FDOT through their web site. Both the Federal Highway Administration and FDOT have funded efforts to add additional capabilities to enhance the programs. The next FDOT release is expected in November 1998 and will include pier design capabilities. The added features of the current release are summarized and the complete users manual is included in this document.
