Bridges engineering

Bridges is the structure element that carrying a road or a path , bridges consist from deck slab , abutment and piers .

Types of bridges :

1-slab bridge : the type of bridge that doesn't have beam , just slab on abutment and piers .

2-T-beam bridge : slab bridge subjected by T- beam consists from abutment , piers , deck slab and T-beam

3- prestressed bridge : type of bridges that have prestressed piers and slabs so the spans will be much longer and the slab is thinner .

4- Box girder bridge : is the bridge in which the main beams consist from hollow box , it may be done using prestressed concrete , steel structure or composite section from steel and reinforced concrete .

5- stayed-cable bridges : this type of bridges has towers to connect the cable with which carry the deck slab.

6-voided bridge : is a bridge that has voids inside the deck slab to reduce amount of concrete and reduce weight of structure , the voids usually circular made from galvanized steel .
