Obtaining the Necessary Precision Index on Deformation Observation Based on Reliability Theory

  • Under the strict of structural safety,this paper treats the measurement error of deformation observation as an equal value load and puts it into load combination,obtains the maximun deformation value Δ under the most disadvantage situation,and from the point of statistics mechanics defines the parameters such as permitting deformation values of deformation object,necessary measurement precision,etc.simple example proves this method reliable.
