摘要
介绍了桥梁承载能力静动态鉴定的理论、试验结果及软件研制。该软件主要用于新、老桥的极限承载能力分析以及桥梁现状的识别鉴定。包括探明桥梁的薄弱部分，跟踪裂缝的发展以及模拟结构的ｐ—δ全过程曲线等。该软件将动态系统识别和非线性承载力分析这两种技术融于一体，并已用于一座实桥的分析，效果良好。
Theory and experience results of bridge bearing capacity identified by dynamic and static method are presented. Software is studied and programed for analyzing the ultimate bearing capacity of the new and old bridge, and appraising the existing bridge. The software, blended dynamic system identification technique with bearing capacity analysis of nonlinearity, can ascertain where the defect part lies and how the crack develops, and simulate structure's full range load deflection curve, ect.
