Identification of structural dynamic load from measured strain response

WEN Xiang rong, MIAO Long xiu (School of Mechanical and Electrical Engineering, Northern Jiaotong University, Beijing 100044, China)  
This paper studies the problem of structural dynamic load identification based on measured strain response, deduces the strain modal matrix of structure measured points, and constructs an efficient and precise equation of load identification by using the high precision integration scheme based on modal decoupling. Numerical examples show the high identification precision of the present method.
