VALIDATION OF DYNAMIC STRAIN MEASUREMENT ACCURACY FOR EVALUATING STRESS TRANSFER MECHANISM IN AN ACTUAL STEEL GYMNASIUM

Abstract

Using a low-cost measurement system utilizing IoT technology, multi-point strain measurements have been conducted over a long period on an actual steel gymnasium. However, this measurement system has issues such as measurement accuracy and time synchronization. Therefore, this paper evaluated the accuracy of dynamic strain measurement for the purpose of assessing a stress transfer mechanism. The variation in stress calculated from the measurement results was quantitatively evaluated, revealing that the stress distribution and neutral axis can be assessed.
