依据结构强度安全度确定安全监测必要精度

DETERMINING THE NECESSARY ACCURACY OF SAFETY MONITORING IN ACCORDANCE WITH SAFETY DEGREE FOR STRUCTURAL STRENGTH

运用结构强度理论在准确定义允许变形值基础上提出依据结构强度安全度确定安全监测必要精度的基本理论模式。将变形观测误差视作结构强度安全度所应容纳的荷载误差之一，按荷载效应组合理论建立各项荷载误差对结构强度影响的传播关系式。

In this paper, by using the structural strength theory, the basic theory model of determining the necessary accuracy of safety monitoring in accordance with degree of safety of structural strength is put forward on the basis of defining accurately the allowable deformation, that is, taking the errors of deformation observation as ones of loaded errors which should be included in the degree of safety for structure strength. According to the combination theory of load effects, the relative formula of propagation of the effects of load errors on structural strength has been set up, the limitation of errors of deformation can be inversed in accordance with the degree of safety for structural strength.
