Analysis of the Reasonable Construction Size of Concrete Bridge Deck

Abstract:

In order to study the reasonable thickness and width of bridge decks of concrete T beam bridge, 36 ANSYS finite element models of simply supported concrete T beam were established, stress performance of each models have been analyzed under the centre load. The analysis results indicated that when the bridge deck thickness reached 22cm, it was no much sense of influence of bridge decks stress and deflection change by increasing the thickness of the bridge deck, therefore, the recommended value of deck thickness was about 22cm. Since the width of the bridge deck has little effect of the mechanical properties and stiffness of it, so the recommended values of the bridge decks width should be determined combined with the diaphragm and the integral stiffness of T beam bridge.
