Bridge Structures

Modern bridge structures need light decks with long durability and promising technical parameters. GFRP bridge deck creates possibilities in bridge designing. Parallel identification of GFRP deck panel: DTA analysis, spectroscopy analysis, scanning and optical microscope monitoring according to own investigation will be presented, in the paper. Modal, vibrations analysis is very important for bridge structures using light Glass Fiber Reinforced Polymer decks. The three 1stmodes and corresponding frequencies have been showed for chosen footbridges with GFRP ASSET system decks. The footbridges were excited by impact and human-induced vibrations. Good exploration of new material, like composite GFRP, generates potential to improve technology and make comparison analysis with traditional standard of materials. The dynamic behavior of damaged footbridge structures under moving loads has been studied. The paper is concerned with a micromechanical theory of macroscopic crack propagation due to stress-corrosion cracking in unidirectional glass-fiber-reinforced polymer composites, for bridge decks applications. The first form of damage in laminates is usually matrix micro cracks, which are intralaminar or ply cracks that traverse the thickness of the ply and run parallel to the fibers in that ply. The identification of early delamination process in footbridges GFRP deck is very important by them durability feature. Improving system for polymer resin using nanostructures is useful by aspect of reducing micro cracks and then macro cracks propagation.
