IDENTIFICATION OF AXIAL FORCES IN MEMBERS OF LAB TESTED MODELS OF BRIDGE TRUSS GIRDERS

摘要

Lab tests of two models of bridge truss girders are summarised. Normal stress distribution was non-linear at analysed cross-sections. Additional FEM investigation was carried out to find normal stress distributions due to bending moments and axial forces. The recorded axial forces were compared to results obtained from numerical analysis of the girders.
