![]() ![]() The author will analyze the setting states and the most suitable location of GFRP bras under the vehicle load on the bridge deck. The analysis mainly includes two sides: one is analyzing the tensile stress of the deck caused by vehicle from Horizontals and verticals the other is about finding the position of the most unfavorable load, and replacing corrosion-resistant GFRP with common steel ,then establishing GFRP reinforced asphalt bridge deck solid model. In this paper, the model of bridge deck structure can be analyzed using solid model of bridge deck established in the principle of the finite element software. It is necessary to analyze the distribution of stress on bridge deck pavement, then design the pavement reasonably. When the number of tower is more than or equal to four, multi-tower suspension bridges have little difference in the mechanical properties and that means multi-tower effect is not obvious.Ībstract: the mechanical analysis of bridge deck pavement is limited at home and abroad.As is known to all,when we referred to the load-carrying capability of a bridge, the deck pavement is surely the weakest part. The results show that the mechanical properties of multi-tower suspension bridge are quietly different from two-tower suspension bridge and with the increase in the number of bridge tower, the displacements of main girder and main tower have large difference. Suspension bridge models whose spans are 1080m with different towers (two, three, four, five, six,) are established to analyze the change in the mechanical properties under the action of vehicle load. For better grasp the difference of the mechanical properties, Midas civil 2011 is used to model to analyze. Due to the increase in the number of tower, the mechanical behavior would be inevitably different with the ordinary two-tower suspension bridge. In order to achieve longer span capacity, long-span multi-tower suspension bridge programs were repeatedly proposed. Abstract: As a bridge with a large span, suspension bridge has obvious advantage in the current cross-sea engineering.
