桥梁结构基于高维模型拟合响应面的参数识别
Bridge Structural Parameters Identification Method Based on HDMR Response Surface
摘要
Abstract
A method for structural paramters identification based on high dimentional model representation (HDMR) response surface is proposed to improve the response surface method applied to bridge structure parameters identification.With the HDMR response surface method,the implicit function relationship between structural parameters and responses is obtained,which is then applied to identifing the structural parameters through a constrained least square optimization strategy.The construction process of HDMR response surface is researched and based on which the implementation program of structural parameters identification is presented.Numerical examples,which contain a continuous beam structure and a single pylon cablestayed bridge,are given to investigate the computational accuracy and efficiency of the proposed method in structural parameters identification.The analysis results show that the proposed method possesses a remarkable advantage in computational accuracy,which is reliable and applicable in the parameters identification of large bridge structures.关键词
