Analysis of Reasonable Reinforcement Structure of Concrete Bridge Deck
In order to study the impact of reforcement stress and concrete cracking of concrete bridge deck caused by the difference of reforcement diameter and spacing, the sub-model analysis was adopted, the bottom horizontal reforcement stress and concrete cracking affected by different diameter and spacing were analysised. The analysis results indicated that When the reforcement spacing was greater than 10cm, the concrete under the most unfavorable position of load would crack; in the vehicle the most unfavorable position, the concrete would crack; When the reinforcement specing was not more than 10cm, if the bar diameter was greater than a certain value, the concrete would not crack. Meanwhile, with the increase of reforcement diameter, steel stress decreased, the possibility of concrete cracking reduced. Combined with the analysis results, the reasonable diameter and spacing of underlying transverse reinforcement of concrete bridge deck were given, the diameter and spacing of other reinforcements of the bridge deck were recommended.
