Objectives

BACKGROUND
The design and fabrication of steel structures requires a good knowledge in the areas of analysis of structres, construction good practices and codes.

SPECIFIC AIMS: Give the students knowledge in the analysis and design of steel structureswith particular enphasis in single and multi-storey buildings.

PREVIOUS KNOWLEDGE:
The students are required to have a sound knowledge in the areas of Structural Mechanis: Statics, Structural Analysis using displacement method, and Strength of Materials.

PERCENTUAL DISTRIBUTION.
Scientific component: 50%
Tecnhological component: 50%

LEARNING OUTCOMES. With this course the student will learn to design steel structures with enphasis in single storey or multi-storey frame buildings which involves:
- Defining actions acording to relevant standards such as EC1.
- Structural analysis using software codes.
- Section Design and stabily check using Eurocode 3.
Design of connection details using EC3.

Program

1 - Type of structures and stability requirements. Analysis of truss systems, trussed frames and portal frames. Bracing requirements in industrial and office buildings.
2 - Structural Design Fundamentals. Allowable Stress Design and Limit State Design. Strength and Serviceability Limit States. Definition of structural loads, factored loads and their combinations according to design standards. Dead loads, imposed loads, wind loads, snow loads and seismic loads .
3 - Design of sections � Section classification. Design of tension members. Design of compression menbers. Buckling length in portal frames. Beam design stability. Design of built-up I sections (girders). Lateral torsional buckling verification. Interaction bending and compression.
4 � Computer Aidede Design of structures.. Modeling the structure and loads. Analysis of member forces and design. Analysis and design of bracing systems.
5 - Design of bolted and welded connections. Beam to colum connections, beam to beam conections. Truss noed design. Column base design.

Teaching methods and learning activities

The course has two components: the students will attend formal classes in the desing of streel structures, according to point 2b) Contents and, will elaborate a projecct of a steel structure, involving both analysis, design and of the overall structure and components acording to Building Codes.
