Introduction
In the event that the health authorities announce a new period of confinement due to the evolution of
the health crisis caused by COVID-19, the teaching staff will promptly communicate how this may effect
the teaching methodologies and activities as well as the assessment.
Structures 2 focuses mainly on the resolution of steel structures, from an initial approach to the choice of structural typology, simplification, resolution and results.
We have established an ordered working methodology which, through successive simplifications and a reasonable amount of time, will give an idea of the structural behaviour of the initial approach. In other words, an understanding of general behaviour will be more important in achieving a good structural approach than knowing the stress state of each individual section.
Pre-course requirements
-Fiscal area and burden-sharing
-Planning the force equilibrium of a beam
-Finding reactions, shearing and bending moments
-Understanding the basic bending moments of hyperstatic structures
Objectives
At the end of the course, students should be able to resolve simple isostatic steel structures, planning the force equilibrium for each mode and bar, extrapolating the stresses to which the structure is subjected, and representing this data in graphs.
Once the graphs have been completed, students should be capable of pre-dimensioning them with textbook metal profiles, using current regulations. Basically this requires knowledge of pre-dimensioning of beams (to bending and shear test) and pillars (with or without buckling).
As well as learning about steel structures, students should also acquire the minimum basic knowledge for planning wooden structures.
Competencies
12-T - Ability to conceive, calculate, design, integrate in buildings and urban complexes and execute building structures
17 - Ability to apply building and technical standards
24 - To acquire adequate knowledge of the mechanics of solids, continuous medium and soil as well as the plastic, elasticity and resistance properties of materials for structural works
Learning outcomes
At the end of this course, students should be able to:
-Draw accurate stress diagrams with the relevant signs
-Distinguish between tangential and normal stresses
-Identify the stresses generated by forces in different parts of a bar and for different types of sections (essentially laminated and circular profiles)
-Pre-dimension 3D metal structures using isostatic models and occasionally simplified hyperstatic ones
-Have sufficient knowledge to correctly plan wooden structures
Syllabus
- BLOCK 1 – THEORY AND PRACTICAL EXERCISES
- BLOCK 2 – PRACTICAL APPLICATION TO THE PROJECT
BLOCK 1
Explanations of the theoretical topics making up the Structures II course will be combined with practical exercises in class involving the direct application of what has been taught.
1 – Introduction + REGULATIONS – Axial Force
2 – Bending Force
3 – Shear Force and Torque
4 – Pure Bending
5 – Complex Unsymmetrical Bending
6 – Buckling I – Unstable supports
7 – Buckling II – Unstable supports
8 – Plastic Calculation (axial and bending)
9 – Joints and welds steel
10 - Introduction to the calculation of wooden structures
BLOCK 2
This section will put into practice the knowledge acquired in the theory classes by applying it to the project that students have been developing in the PROJECTS course. Thus part of the project that involves a metal (preferably) or wooden structure will be taken in order to find a solution (equilibrium – diagrams – dimensioning) until reaching executive project level for the selected section.
1 – Presentation of structural proposal on the student’s own project
2 – Axial force in the project: presentation of pre-dimensioned metal/wooden pillar
3 – Bending force in the project: presentation of pre-dimensioned beam
4 – Shear force and torque in the project: presentation of detail of the anchoring, pins, etc.
5 – Buckling: presentation of a pillar calculated for buckling
6 – Examination-type beam assignments
7 – Examination-type ‘tubing’ assignments
8 – Presentation of executive Structures project. Review of subject matter and any queries about the examination
