Practice 1. Identification and idealization of structures Objectives and development:
The student is expected to put into practice and consolidate the knowledge acquired in unit 1 while reviewing concepts of statics of structures previously acquired in subjects such as Physics and Elasticity and Strength of Materials. For this, different examples of real structures will be proposed to be idealised, determining their design loads and analysing their stability. n addition, this practice will be complemented by a visit to different buildings of the ENM in which students will be able to identify some of the types and structural elements studied.
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. 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 several practical cases raised by the lecturer. This practice is related to units 2, 3 and 4.
Practice 4. Analysis of reticular structures with articulated and rigid knots Objectives and development:
This practice aims to reinforce the knowledge related to units 1, 2, 6 and 7 of the subject. For this, different demonstrative assemblies of models of articulated knots and rigid knots bar structures will be made, on which the students must carry out different measurements of deformations. In addition, exercises will be solved that will reinforce the understanding of the behavior of this type of structures.
Practice 5. Matrix methods of structural analysis Objectives and development:
This practice is intended to introduce the student to the use of matrix methods for the analysis of structures. A series of exercises will be solved through the programing of the stiffness method in a Matlab-type software. This is a practice related to unit 8.
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.
