Course Details

1. Describe the structural system of Metallic and Wood structures.
2. Explain that the main structural system of such structures is consisted by precast two types of structural elements, beams and trusses connected at the place of the structure.
3. Distinguish the typical sections of metallic and wood beams and the different between these typical forms.
4. Justify the structural behaviour of the beam and the truss and the support conditions of such structural elements.
5. Create the connection joints of two structural elements.
6. Use various techniques to increase their strength and especially their stiffness.
7. Design complicated Metallic and Wood structural systems using the benefits of the previous described structural elements.
8. Analyse simple cases of structural forms including estimation of external loadings and the selection of the dimensions of structural elements.

Typical sections of structural elements: Emphasis is given to understand the linearform of steel or wood structural elements (beams and trusses), the differences of the typical sections of such elements related to the production procedure,the physical and mechanical properties of steel and wood, and the procedure to estimate the strength and stiffness o such elements.

Connection joints of structural elements: Various technique show to create the connection joints of metallic or wood structural elements and their support conditions are examined. The students make in situ investigation to real structures including design of connection joints and analysis of the role of the various parts using for the connection joints.   

Design and calculations of simple isostatic structural systems: The students have to be familiar to complete all the stages for the design of simple isostatic structural systems, with beams or trusses, including the procedure of estimation of external loading, selection of the dimensions of structural elements, making calculations to find the stress of such elements and making all the checks to accept or not the selected sections. Through simple exercises they can understand the complicity and the necessity of this procedure, the main role of each structural element to the structural system, the possibilities of failure or collapse of a structural system due to the overloading or due to the low strength of structural elements and   the possibility and the necessity in many times for the check and redesign of a structural system.  

Design of complicated structural systems: Main emphasis is given for the application of the knowledges and experiences form the previous stages as well from the prerequisites lessons (BATECH15 &BATEC14) for the design of whole metallic and wood structural systems. The concept of the structural system taking in the account the parameters of the strength, the stiffness, the way transferring the external loading, the connection joints of structural elements and the foundation support conditions are examined and discussed in various cases.

• M. Demosthenous “Static of Metallic and Wood structures” – Lecture Notes

The taught part of the course is delivered to the students by means of lectures and a number of numerical exercises. Lecture notes are available through the class for students to use in combination with the relevant textbooks and other notes.

Lectures are supplemented with two project works (assignments) carried out on an individual basis. In the first project, students are requested to investigate possible cases for the connection of metallic and wood structural elements, to check the possible failures of an existing structure due the overloading and to design a simple wood bridge using sections of wood beams offered by the market.At the second project, at the first stage the students make a market investigation to find the steel sections of structural elements offered by the market. At the second stage the students design the structural system of a metallic structure, such supermarket, parking place e.t.c., giving all the drawings, including details for the connections and descriptions about the stiffness of structure and the loading transferring form the roof to the foundation.
