MIEM | 16 | Syllabus since 2006/2007 | 5 | - | 6 | 56 | 160 |
This syllabus presents methodologies for design of metallic structures.
The international specifications regarding the design of metallic structures are presented, namely the Eurocodes set of Norms. State of the art solutions for the implementation and execution of the structures are also presented.
The design of metallic structures requires a solid background in Structural Mechanics as well as a good knowledge of execution norms and structural safety standards.
The students will acquire competences for the design of metallic structures with respect to:
- Selection of the structural solution
- Design of structural components and connections
1- Stability requirements in metallic structures. Bracing requirements in industrial and office buildings; Definition of wind bracing.
2- Principles of structural design - Allowable stress design, Ultimate limit state design and serviceability limit states; Definition of structural loads: wind loads, snow loads, seismic loads, etc; Relevant load combination rules according to Eurocode 1.
3- Computer Aided Structure Analysis. Structure modelling: geometry, materials, resisting sections and loading. Analysis of beam stress and resistance of different components; Analysis and developmentof wind bracing systems.
4- Design of the resisting section according toREAPE (Portuguese Norm for steel structures of buildings) and EC3. Classification of sections. 4.1- Bars under axial compression. 4-2- Buckling length in portal frames.
5- Girder design; Girder stability in PRS profiles (welded reconstituted profiles); Lateral buckling on open section girders
6- Critical stress in plates subject to loading in the middle plane; core instability in PRS profiles (welded reconstituted profiles); interaction formulas related with simultaneous normal and tangential stress.
7- Design of bolted and welded connections; beam to column connection; beam to beam connection; truss design. Column base design.
Theoretical-practical classes will be based on the presentation of the themes of the course and complemented with examples. At the same time, students will be ask to develop a project consisting of the Design of a Metalic Structre which will cover al the items of the above program. This project will be supervised by the professor during the semester.

The students are required to attend at least 75% of the classes.
Final evaluation on the syllabus will be done with the presentation of the project by the student. The report of the project will consist of a document containing design specifics and general engineering drawings of the project.
The project report will be presented no later than the dates specified for the examination of the syllabus.
