2.3. Structural Behavioural degradation factors. Splits, breaks and deformations caused by force.
2.4. How to Project wood in modern constructions. Protection treatments for surface and below.
2.5. Repair of constructions in rehabilitation. Treatment cures for elements which have been degraded either abiotically or biotically.
2.6. Research systems for structural problems. Support or substitution of structural elements.
2.7. Complete rehabilitation of wooden structures. Bending of forms and consolidation.
3. The construction methods. Typologies of wooden constructions.

3.1. Description of the elements. Beams and pillars, small windows and joints. Brackets and division methods. The light framework of the construction model.

3.2. The construction with wood as a sustainable technique.
3.3 The exploitation of re-forestation.
3.3. List of conditionals and quality control of wood.
3.4. Mixed structures used for pre-fabricated walls and wooden ceilings. Evolution of traditional systems and new mixed techniques.
3.5. Light framwork method (`Platform frame´). Development of a building, the Project, the
record, a list of the conditions of the specific elements of wood. Models and graphic representation.
3.6 Special panels and iron work. Preconstruction system of new wooden buildings. Light panels and integral systems.
3.6. Laminated wood. Porticos. Comparison of the structural aptness of wood, concrete and metallic structures.

4. Calculating the wooden structure.
4.1. Calculation rules. The classification of chipboard, laminated wood and plasterboards. The importance of the stamp of quality.
4.2. The structural behaviour of the light framework (`platform´). Difuse structure of minor elements. Stability of the building using horizontal and vertical frames. The role of structural plasterboard.
4.3. Calculation of the elements (beams, joints, supports). Difference between the permanent loads and the instantaneous ones.
4.4. Calculation of laminated wood porticos. The problems of big lights and big supports. The stability of the structure against horizontal forces.
4.5. Predimensioned criteria of light wooden frameworks. The importance of the model in the calculation.
4.6. Estimation of the strength of wood in rehabilitation work. Recognition of how the structure works identification of the type of wood and its strength. The calculation of the existing structural element.

Methodology
