PRESENTATION:

This course is about reinforced concrete structures.

Reinforced concrete is the most used building material for building structures. Its virtue is its ability to be moulded, so that it takes up the shapes required for every structural form. It is also very durable and fire resistant. Concrete can be used for all standard buildings both single storey and multi-storey and for containment and retaining structures and bridges.

The course will take students from initial basic concepts, that will allow them to make quick and easy pre-dimension; to the full calculation of a reinforced concrete structure, considering ultimate limit states and serviceability limit states. At the end of the course the student will be able to produce full detailed reinforced concrete projects.

This course will follow the rules stablished in the Spanish Building Code (CTE) and the Structural Concrete Norms (EHE-08).

PRE-REQUISITES:

It is advisory that every student that enrols in this course has basic knowledge about mechanics of materials taught in “Estructuras I” and structural analysis taught in “Estructuras II”. It is also advisory that students have some upper intermediate level of English. 

It will be supposed that every student remembers some basic math skills, including basic algebra and trigonometry, as well as some basic calculus topics (such as differentiation, simple integration, and how to find maximum and minimum values of functions). The student should be proficiency in geometry and trigonometry. Being familiar with the cartesian coordinate system and its terminology as well as knowing the basic rules governing sines, cosines and tangents of angles is invaluable as you work mechanics of materials problems.

SUBJECT PROGRAMME:

Observations:


The course will begin with some basic concepts about reinforced concrete structures. The materials and their properties, quick tools to design RC structures, and basic knowledge to understand the global concepts of the course.

Afterwards, the course will teach about structural calculations, following the ultimate limit state method. The student will learn to design and verify reinforced concrete beams and pillars, as well as draw the detailed section considering the spacing requisites stablished in the codes. Some basic concepts about design following the serviceability limit states will also be taught.

The course will conclude with some theory and exercises about foundation calculations. Students will learn to design both, shallow and deep foundations.

TEACHING AND LEARNING METHODOLOGIES AND ACTIVITIES:

Teaching and learning methodologies and activities applied:

To achieve the course competencies established in this guide, the activities are planned as follows:

There will be several theory sessions where the teacher will transmit the new information through oral and written exposition, conveniently using ICT as auxiliary means. The theory sessions will mainly be taught online, via Microsoft TEAMS. The exposition will be oriented to the course development; the new concepts will be structured in a coherent and logical way. The basic ideas and philosophy of the subject will be explained, avoiding extensive demonstrations that conspire against the understanding of the fundamental ideas of physics - which does not mean that mathematical demonstrations are less important. If circumstances require it, other theory activities not contemplated in the initial programming may be adopted. During the expositions questions or problematic situations may be asked. There will be some small practical activities. The teacher will solve any possible doubt or incomplete information, guiding and motivating students to search for answers, generating debates and creating an active class environment.

There will be practical sessions related to the previous theory ones. The practical sessions will mainly be taught in the classroom, giving way to a more social interaction with the students to solve any practical doubt using the blackboard. Students must prepare the practical activities prior to the realization of the session and study every concept needed to solve exercises. There will be some small written tests to check the evaluating competences are being met.

After every theory session, to prepare for the following practical session, there will be some, mostly individual, coursework that each student must complete before the beginning of the next session. For this, the student must study each new concept and practice solving exercises on their own.

There will also be a course project that will be developed in an autonomous way. The project will evaluate every concept of the course and will be done individually. Each student will work on their project with the obligation to bring material to work in class, as well as doubts or questions that have arisen during the autonomous work to be able to solve them together in class. Students will be able to ask the professor their doubts in person during tutoring hours or via email.

To conclude with the course project, there will be a last task to be carried out in groups. And will evaluate the capacity of the students to explain a structural project to their classmates as well as building an actual reinforced concrete structural model.
