Concrete and steel as structural materials. Design of members for tension, compression, shear, and flexure. Welded and bolted connections. Limit-state design concepts. Serviceability.

The objective of the course is to introduce the students to the use of concrete and steel as structural materials and to the principles of structural design.

It builds on the acquired knowledge of mechanics of materials, metallurgy, and structural design and analysis for statically determinate elements covered in previous courses.

Learning Outcomes

  • At the end of the course, students are expected to:

  • Understand the behaviour of structural steel, reinforced concrete and prestressed concrete elements, and from this, key design concepts for such elements.
  • Be able to apply the principles of mechanics to calculate the resistance of reinforced concrete and steel structural elements.
  • Understand the performance of steel and concrete members subject to tension, compression, shear, flexure actions and combinations of these.
  • Be able to follow design procedures for the above.
  • Understand the limit-state design approach, including serviceability and ultimate limit states as it applies to steel and concrete structures.
  • Be able to follow design methods and techniques for a variety of welded and bolted connections. Be able to design and/or analyse reinforced concrete beams and reinforced concrete column elements as part of a real building structure.

Timetable Note

Laboratory Components

Two laboratory sessions are held in this course; one for the Steel and one for Concrete. As these sessions are held in the structures laboratories, it is essential that you wear proper footwear to these sessions, or you will not be allowed to participate in the experiments for safety reasons.

Structural Steel laboratory (CW) 3 hrs/student
The Structural Steel laboratory exercise will take place in the Model Structural Laboratory and consist of two experiments:

Experiment 1 allows students to determine the strength and deformation of ductile members, considering effects of local buckling. In experiment 2, students will test a C-section member. Section properties are obtained as a distribution, based on a range of measurements. This results in a distribution of response that will be compared with experimental results. The member shear centre is also found experimentally.

Reinforced Concrete laboratory (TS) 3 hrs/student
The RC laboratory exercise will take place in the main Structural Laboratory and consist of demonstration tests on reinforced concrete columns. The class will be divided in two streams and actively participate to the testing until failure of two different reinforced concrete column specimens (the first in RC Lab 1 and the second in RC Lab 2) under quasi-static cyclic lateral loading.

A laboratory report, in which students describe the test set-up, compare experimental force-displacement and moment-curvature results with their predictions and discuss/explain the observed behaviour, will be required at the conclusion of both labs (see lecture schedule). In addition, each student will be required to predict, prior to the RC Lab 2 test (see lecture schedule), the force-displacement response of the column elements.

Credits can be given to repeating students for the laboratory component and/or for the concrete and steel parts independently, after consensus of the lecturer in charge.

The request should come in writing (email sufficient) to the lecturer in charge of that part of the course (and copied to the course coordinator), no later than the second Friday of the respective Term (i.e., T3 for steel ad T4 for concrete).
