一种结合有限元程序的桥梁荷载试验分析方法

A bridge load test analysis method combined with finite element program

荷载试验已经成为结构健康与安全的有效研究手段。桥梁荷载试验是基于设计文件,同时考虑桥梁服役年限,对设计参数进行适当折减后进行数值模拟,得到桥梁的理论指标。以实际背景桥梁为例,进行结合有限元程序的荷载试验方法的说明,并对结合有限元的荷载试验方法注意事项进行探讨。

Load test has become an effective research method for structural health and safety. The bridge load test is based on the design documents and considering the service life of the bridge. After the design parameters are properly reduced, the theoretical indexes of the bridge are obtained. Taking the actual background bridge as an example, the load test method combined with the finite element program is explained, and the precautions of the load test method combined with the finite element program are discussed.
