Appendix B. Inventory of U.S. Cable-Stayed Bridges

An inventory of cable-stayed bridges in the United States was created to organize and share existing records with the research team. This database includes information on bridge geometry, cable properties, cable connections, aerodynamic detailing, site conditions, and observed responses to wind. The inventory is stored in Microsoft Access (Microsoft Office) database format, which allows for easy data entry and retrieval. Forms were designed to perform this task, complete with pull-down menus and control buttons, using the Visual Basic® programming language. These forms for data entry include a "switchboard" form and three categories of bridge data forms: General bridge data, cable data, and wind data.

Overall, 26 bridges have been added to the database, including several from outside the United States. Copies of contract drawings from which data was taken have been copied and filed for future reference. The following is the full list of bridges included in the inventory:

The inventory forms are described in detail in the following pages.

Switchboard

Overall control of data entry and referential integrity between categories is provided by a switchboard from which the user selects which type of data to enter or retrieve. An example of the switchboard is shown below. The user may select from the three categories to either add a new entry or edit an existing entry. The selection will open data entry forms for the category requested.

General Bridge Information

General bridge information is divided into two sections. General information includes bridge name, designers, suppliers, and bridge location. Structural data includes information on the superstructure, tower, cable, anchorages, and crossties.

Cable Data

Cable data is divided into four sections: Cable geometry, cable properties, cable connections, and aerodynamic details. Cable geometry gives the end coordinates and calculates the cable length. Cable properties include strand type, size, dead load tension, and the protection system. Cable connections describes upper and lower anchors and fatigue test information. Aerodynamic details include descriptions of dampers and sheathing surface treatment. Information for each cable of the bridge is given individually.

Wind Data

Wind data includes bridge dynamic modes, superstructure mass, design wind speeds, and vibration measurement information. Data has only been entered for the Cape Girardeau Bridge.
