Unit 3. Normative frame in the calculation and design of structures and industrial constructions Objectives and development:
The codes currentluy in force for the design of industrial constructions and the calculation of their structures will be presented. The criteria of structural security that govern the calculation of structures in Spain and in the European Union will be studied. This includes the determination of the loads on a structure. Besides, an apporach to different criteria that must be taken into account in the design and the construction of industrial buildings: evaluation and prevention of risks in the construction phase, security of utilisation and accessibility, energy saving and use of renewable energies, healthy indoor environment, noise protection, etc.

Unit 6. Analysis of reticular structures with articulated knots Objectives and development:
The main features of bar structures with articulated knots will be defined and their main types will be identified. Different analytical methods will be studied to determine stresses and deformations in both isostatic and hyperstatic structures. The results obtained with this type of analysis will be related to the fundamentals of metal structures design, seen in unit 4.

The behavior of bar structures with rigid knots will be analysed. The fundamentals of the method of Cross of distribution of moments will be presented as tool of analysis of this type of structures. This method will be applied to determine the internal forces in hyperstatic beams and frames. The results obtained with this type of analysis will be related to the fundamentals of design of metal and concrete structures, seen in unit 4 and 5, respectively.

Unit 9. Buildings in the Spanish Navy Objectives and development:
Some of the most relevant aspects of constructions in the Armed Forces, and in particular the Spanish Navy, will be estudied. Different cases of buildings present in military units and bases will be analyzed from the constructive and structural point of view. It is intended that this unit serves to review and apply some of the most relevant content of the course through its contextualization in a more familiar environment, and if possible more motivating, for the students.

Index:
9.1 Examples of buildings in military environments
9.2 Management of building projects in the Navy
Practice 1. Identification and idealization of structures Objectives and development:
With this practice, it is intended to complement the contents of the first two units of the subject, as well as to review basic knowledge of structural stability, acquired in previous courses. Different examples of real structures will be proposed for the student to idealize, determine their external loads and analyze their stability. In addition, this practice will be complemented with a visit to several buildings of the ENM in which students will be able to identify different types and structural elements studied during the course.
Practice 2. Determining design loads on industrial buildings Objectives and development:
This practice aims to introduce the student to the management of the current regulations applicable to the design of structures, in particular to determining loads according to CTE. For this, an exercise is proposed in which the students must determine the loads actuating on different structural elements of an industrial warehouse. This practice is related to the first three units of the subject.
Practice 3. Sizing structural steel elements Objectives and development:
With this practice, the students are expected to complement and expand their knowledge on calculation and combination of loads, applying them to the dimensioning of different elements of steel structures. For this, the student will solve one practical case raised by the lecturer. This practice is related to units 2, 3 and 4.
Practice 4. Introduction to reticular structures with articulated and rigid knots Objectives and development:
This practice intends to introduce the student to the study of structures based on bars with articulated knots or with rigid knots, which will be approached, respectively, in units 6 and 7 of the subject. Different demonstrative assemblies of models of articulated knot and rigid knot bar structures will be carried out, in such a way that students can visualize and understand the behavior of these structural typologies under different external loads.
Practice 5. Analysis of deformations in trusses Objectives and development:
In this practice, deformation measurements will be made in a truss model under different load conditions. Likewise, a theoretical approach to the experimentally measured results will be carried out. The main objective is to reinforce the knowledge acquired in unit 6 of the subject.
Practice 6. Introduction to the use of professional structural calculation software Objectives and development:
In this practical session, the student will be introduced to the management of professional structural calculation programs with a dual objective: i) to promote the consolidation of basic knowledge on design and calculation of structures acquired throughout the course; ii) show the possibilities offered by a professional structure calculation software. There will be a brief presentation of the software available at the center (Autodesk Robot Structural Analysis) and the sizing of different structural elements and simple structures will be carried out
Practice 7. Social, environmental, safety and health aspects in the design and construction of industrial buildings Objectives and development:
Students, working in groups of three to five people, must present and defend a work on different social, environmental, safety and health aspects that according to the Technical Building Code and other reference regulations must be taken into account in the design and the construction of industrial buildings. These works will be raised by the lecturers of the subject during the teaching of unic 3. The result of this practice will be evaluated within the Group Work item (TG), according to what is established in the Assesment item of this teaching guide.
