基于贝叶斯理论，针对五层框架结构，利用模型更新的原理对结构物理参数进行识别-Based on the Bayesian theory, the structural physical parameters are identified by the principle of model updating for the five-layer frame structure

基于MH算法的贝叶斯模型更新，结构为五层框架结构，更新得到结构的物理参数-The Bayesian model based on the MH algorithm is updated and the structure is a five-story frame structure. The physical parameters of the structure are updated
