Data Missing Mechanism in Construction Monitoring and Its Treatment

Abstract:

This paper categorizes the missing data into three kinds by their generating mechanism and characteristics. Data processing and compensation methods are proposed on the basis of the regression analysis by least square method. A comparative study of the monitoring data about the steel structure of Datong Art Gallery in Shanxi Province and “the ring of life” in Shenyang City of Liaoning Province confirms that the proposed methods for missing data treatment are effective and practical.

Key words:construction monitoring of steel structure; data missing; data processing and compensation methods; initial value
