Aims

To learn designing of all type of concrete bridges for bridging over different barriers.
To gain knowledge about basic methods of the bridges construction including their effects on structural design.
To gain essential knowledge about design of special types of bridges in some special conditions.
A student gains these knowledge and skills:
• Virtue for designing special type of concrete bridges for bridging over different barriers.
• Knowledge of basic methods of the bridges construction including their effects on structural design.
• Essential knowledge about design of special types of bridges in some special conditions.
