Deflection calculation for beam-type structures from measured strain data

Abstract

Behavior of structures under various load types is determined by their deformation characteristics, global deformation characteristics-deflections and rotations, and local deformation characteristics – strains / stresses in structure base material. If we know global and local deformation characteristics of a structure, then it is possible to determine the structure behavior under acting loads, on the whole structure or at some part of that structure. The main objective of this research is to verify calculation algorithm for obtaining vertical displacements-the deflection of the structure, based on the known strain values in the structure base material, under acting load. The verification of the calculation algorithm is performed by comparing the numerical and experimental results.
