Information Acquisition Method based on Space Similarity Structure

摘要

The structural health monitoring method based on space similarity structure is proposed in this paper,the aim of which is to utilize the limited members’ information measurement to obtain the whole structural state and make its safety estimation.The steel structure of Shenzhen Futian Traffic Center is made up with six curved steel trusses which are structural similarity and beam string pre-stressed,which is a project used in this paper.It combines data mining and multivariate statistic analysis,gives the main factor which can evaluate the member’s working state,proposes the method which can get complex steel structure members’ information from the limited ones.On the basis of information acquisition for single truss,the six trusses information is gotten finally.It explains the expansibility of this method on the basis of proving the method’s feasibility and validity.
