- This course is intended for students that want to expand their knowledge in the field of structural design, obtaining thus, the necessary background for the scientific concept, design, composition and use of rational design, conceptual use of various structural elements and their role in the building within the overall design of the building. The trade-offs between the physical part and economical requirements will be presented. The course comprises both synthetic and consistent treatment of the fundamentals of seismic design for structures located in seismic zones, in terms of: service, material, structure. General requirements for a performance based design is discussed, being formulated and analyzed both the general criteria on the overall composition of the building, and specific design criteria for earthquake resistant structures in conjunction with severe structural elements, equipment, etc. Some other topics discussed are related to buildings situated in natural and built difficult environments and the structures required in such cases. There are also the concerns of the interdependence between the structure and conditions of its development: technology, organization, economy.
The course has the following goals:
1. Understanding the history and philosophy of main standards and regulations.
2. Understanding the fundamentals of seismic engineering and structural dynamics.
3. Ability to analyze the fundamental parameters that govern the structural response.
4. Understanding the trade-offs needed for buildings situated in difficult terrain environments.
5. Ability to design and select the appropriate structure for land transfer loads to the foundation based on a given set of economical, environmental and physical factors.
6. Ability to appreciate different foundation procedures on difficult terrain environments through case studies that illustrate the analytical procedures and check their applicability.
7. Understanding the philosophy and the algorithms for different structural software, to view seismic movement for an efficient design process related to dynamic analysis, to optimize the design of various structures.
8. Understanding modern technologies used for design and analysis of buildings located in seismic areas.
