### Course content

Design principles. Mechanical properties of steels. Elastic and plastic capacity of members. Elastic and inelastic buckling of struts. Beam-columns. Bolt and weld connectors. Introduction to design of basic structural joints.

### Learning outcome

Steel Structures 1 is the first design course for students in their specialization within Structural Engineering. Together with TKT4230 Steel Structures 2 the course offers a rather comprehensive introduction to the field of design of steel structures. The two courses present the theoretical background for the methods of analysis and design as implemented in the design codes for steel structures, for the time being Eurocode 3. The topics of Steel Structures 1 are cross section capacity, buckling and connections. Steel Structures 1 has these learning objectives: Knowledge: - Calculation of stresses in cross sections, applying theory of elasticity - The lower-bound theorem of plasticity and how it can be applied in the development of interaction formulas for determination of plastic cross section capacity - Saint Venant's torsional theory - Elastic and inelastic buckling - The main types of connections, i.e. bolts and welds - Typical design of joints in steel structures. Skills: - Determine the necessary size of a cross-section, for use as axial force member, beam or column, such that it can carry the applied loading. - Calculate the cross section capacity by the theory of elasticity or plasticity, and check the capacity to Eurocode 3 - Calculate shear stresses and twisting angle related to Saint Venant's torsion - Determine the buckling length of members with elastic supports - Check the capacity of columns and beam-columns to Eurocode 3 - Determine forces and stresses in bolted and welded connections - Check the capacity of bolted and welded connections to Eurocode 3. General competence: - The theoretical foundation for analysis and design of steel structures - The background for relevant clauses in Eurocode 3 - Calculate and design simple steel structures subjected to static loading.

### Learning methods and activities

Lectures, weekly assignments, computer exercises and a welding exercise in lab. 2/3 of the assignments and computer exercises must be approved prior to the examination.

### Compulsory assignments

• Written exercises and small project

### Further on evaluation

In case of delayed examination an oral examination may be given.

### Specific conditions

Compulsory activities from previous semester may be approved by the department.
