Learning Outcomes of the Curricular Unit:
It is intended that the student be able to solve spatial hyper-static structural systems subjected to static loads, composed of linear elements, the beam type and pillar structures as well get a perception of how such a model is capable of adapting to laminar elements such as slabs and walls, and when such limitations are legitimate. Also, to undertake the study of the characteristics and behavior of a vibrating reticulate, flat or spatial structure, integrating with the seismic acceleration recommended in Eurocode 8 in order to obtain the same forces of nature. It is also intended to determine, analyze and integrate the previous two analyzes, in order to obtain the forces and displacements that lead to the verification of safety (ULS and SLS) and design of structural elements.

1.2.3. Stiffness matrix of a bar in local referential.
1.2.4. The transformation matrix / rotation.
1.2.5. The stiffness matrix of a bar on a general framework.
1.2.6. Formation of the global stiffness matrix.

Demonstration of the Syllabus Coherence with the Curricular Unit's Objectives:
The contents were carefully chosen, the themes and its depth, and are taught in order to allow a continuous and gradual learning of knowledge, in the sense that the student achieves the proposed objectives and gain the required skills.
Selected topics fulfill the objectives of the proposed teaching and learning subjects.
Teaching Methodologies (Including Evaluation):
Continuous assessment of knowledge through homework assignments (5%) and two written tests (95%). Expositive presentation of themes, discussion promoted by interrogative and demonstrative techniques, resorting to practical applications. Active method applied in proposed individual works,promoting individual study and research.
Demonstration of the Coherence between the Teaching Methodologies and the Learning Outcomes:
The proposed methodology was carefully chosen based on several years of experience, and seeks to facilitate a gradual and continuous learning, in order to achieve the proposed objectives. The encouragement of a non-contact study of the student facilitates the achievement of the desired levels of knowledge and training. The Bibliography indicated further contributes to facilitated access to the student of the programmatic contents.
