Research in a procedure for evaluation of structural condition from passive monitoring of response to ambient loadings is proposed. The condition monitoring procedure is fully automated, can interface directly with computer-based structural maintenance and management systems, and can provide condition information of a quality and frequency adequate to support an aggressive, proactive maintenance program for structures. Aggressive maintenance can minimize repair costs and interruptions of service in important structures. A database of dynamic strain records obtained in a separate testing program conducted at the university of Colorado involving thirty highway bridges of various spans and construction is available as input to the condition monitoring procedure. With these records a quick and economical evaluation of the condition monitoring method is possible.

结构状态评估方法的研究 提出了被动监测对环境载荷的响应。 状态监测程序是完全自动化的，可以 直接与基于计算机结构维护接口， 管理系统，并可以提供条件信息的一个 质量和频率足以支持一个积极，主动 结构的维护计划。 积极的维护可以 最大限度地减少维修成本和服务中断的重要 结构. 一个动态应变记录的数据库， 在科罗拉多大学进行的一项单独的测试计划 涉及30座不同跨度和结构的公路桥梁 可用作状态监测程序的输入。 与 这些记录了对条件的快速和经济的评估 监测方法是可行的。
