Title:
インフラ要素の構造健全性を決定する方法
Document Type and Number:
Japanese Patent JP6917393
Kind Code:
B2
Abstract:
The invention relates to a method for determining the structural integrity of an infrastructural element, comprising the steps of:measuring deformations, such as displacements or rotations, during a predetermined time period with deformation measurement means arranged at or near a main structural body of the infrastructural element, in particular supports of the main structural body, characterized bydetermining the load configuration of the main structural body over the course of the predetermined time period, such as the load configuration concerning the loading perpendicular to a longitudinal direction of the main structural body,calculating the bending stiffness (EI) of the main structural body over the course of the predetermined time period, from the load configuration and deformations measured by the deformation measurement means, andcomparing the bending stiffness (EI) at the end of the predetermined time period to the bending stiffness (EI) at the start of the predetermined time period to establish a difference in bending stiffness (EI) over the course of the predetermined time period.
