Concrete Structures 1

Principles of strucural design and material properties. Limit-state conditions, stress-strain relations. Ultimate limit-state capacities with respect to uniaxial loading, bending and shear: columns, beams, plates. Deformations, creep, shrinkage and crack-width calculations in Service limit state. Slenderness, calculation of 2. order moments in columns.

The subject offers basic knowledge about design of simple concrete structures, and theoretical background for the regulations in Eurocode2. Concrete Structures 1 is the first design course within design of concrete structures. The course presents the theoretical background for the methods of analysis and design as implemented in the design codes for reinforced concrete structures, for the time being Eurocode 2.

Concrete Structures 1 has these learning objectives:

Knowledge:

• Mechanical behaviour of concrete and reinforcement steel under short- and long term loading
• Design and resistance in ultimate limit state for element subjected to axial and shear forces, bending and torsional moments and combination of these
• Design of slender columns with second order effects
• Calculation and control of displacements and crack widths in serviceability limit state
• Detailing of different concrete members.

Skills:

• Design beams subjected to shear force, bending and torsional moments
• Design slabs for bending moment and shear force
• Design columns i frame structures for 1.- and 2. order actions
• Control anchoring capacity of reinforcement
• Calculate displacements and crack widths in slabs and beams including creep and shrinkage in the concrete.

General competence:

• Design of simple concrete structures subjected to static loading according to Eurocode 2.

Digital competence: Qualified use of a static program to model and analyse frames and one-way slabs with focus om loading and load combinations. Competence to interpret and assess results from a static program.

Sustainability competence: The course contributes to design of safe, economical and sustainable concrete structures. Design of durable structures with long service life. Choice of material to minimize the environmental impact from concrete.

Lectures and compulsory calculation and computer exercises.
