The proposed database framework described herein integrates current existing bridge information sources with new information to provide a uniform database to use for modeling damaged bridges. The database includes the following information: bridge design information (design documents, construction, drawings, etc.); environmental (geographic and weather) conditions; hazards information and traffic conditions; bridge damage and loss information (damage positions and damage modes, etc.) and economic and environmental impacts. As expected, most of this information is not available, certainly in quantitative terms. Furthermore, in additional to the lack of quantitative descriptions of bridge damage (failures and partial failures), the condition of the bridge at the time of failure is almost non-existent in the documented information/database. This latter information is relevant in damage modeling of bridges. Therefore, the database software described in the report should be regarded as a framework for further refinements, especially in the areas of quantitative information regarding damage and estimated bridge condition at the time of failure. 收起
