Design of Reinforced Concrete Structures 1Laajuus (5 cr)

Objective

On completion of the course the student knows how concrete structures are used as the frame material of a building. The student can recognise concrete structures, reinforced concrete structures and prestressed concrete structures.

The student can determine the material properties of concrete and reinforcement steel as well as the needed concrete cover based on the durability requirements and functional demands.
The student is able to perform needed ULS and SLS checks for a beam including the determination of required time dependent material properties, and to design an appropriate reinforcement arrangement.
The student can calculate the anchorage length and the lap length for reinforcing bars.
The student can determine creeping, drying shrinkage and time-dependent concrete strength.
The student can calculate the deflection and crack width of a reinforced concrete beam under bending moment.
