Prestressed Structures

By numerical simulation and contrasting with experimental conclusions, mechanical models in every loading stage of CFRP reinforced concrete bridge deck were established. The results showed that, numerical simulation results of non-prestressed bridge decks fitted corresponding test results well. The stiffness of prestressed structures had been greatly improved than non-prestressed structures, so the high strength performance of CFRP had been used more effectively.

Extensive Numerical Simulation

<p>This article concerns the behaviour of two blind bolt types, Ajax One side and Blind Oversize Mechanically (BOM), used to connect a multi-void aluminum bridge deck on its supporting steel girders. An extensive numerical simulation by FEM was performed to evaluate the connection behaviour against the Canadian Highway Bridge Design standard CSA S6-19. The main objective was to examine the assembly against fretting and quantify its impact at the contact zone over several load cycles. A special numerical model was developed for the prediction of fretting, and validated with analytical results and other observations reported in the literature. The model was used to analyze the fretting for each bolt at the surface of contact between the bolt head and the aluminum plate. Results of the study revealed that the blind bolts will lead to a few micrometers of wear, while for the standard bolt, a probable crack developments associated with minor wear may occur at the contact area.</p>
