Often influence each other between the factors such as the deadweight of bridge, span, version and erection method and restrict, so
Need a person with the qualifications of a general material, version and erection technique as an interactional entirety in Bridge Design.In view of plane and space
The force-transmission mechanism of truss is more clear and definite, rod member Path of Force Transfer is relatively single, is a kind of higher version of load-carrying efficiency.And it is fine
Dimension reinforced resin base pultrusion composite materials fiber content is high, and stock utilization is high, has excellent unidirectional mechanical property.If by fibre
Dimension reinforced resin base drawing and extruding section bar carries out co-design with truss structure, then can give full play to the advantage of the two, thus reaching big
The purpose of width loss of weight.In addition, rational selection and modular design equally can improve the bearing capacity of bridge structure, if wherein will answer
Condensation material is combined designing in structure with traditional metal materials, can give full play to the utilization ratio of different materials, reach continuation
The purpose of loss of weight.
