| Educational objectives |
he course combines theoretical knowledge of structural mechanics with practical skills related to the design of civil constructions, including the ability to draft calculation reports and detailed design drawings at the execution level. The main objective of the module is to provide students with both the theoretical knowledge and practical skills necessary for the structural analysis and design of pre-stressed reinforced concrete elements, as well as surface-developing structures such as slabs, tanks, and special structural elements. The main knowledge acquired (Dublin Descriptor 1) includes: - Theory of pre-stressed reinforced concrete - Linear analysis under small displacements of surface-developing structures - Common structural schemes used in buildings and bridges The main skills acquired (the ability to apply knowledge, Dublin Descriptor 2, and to independently adopt appropriate approaches, Dublin Descriptor 3) include: - Designing and graphically representing structural elements in reinforced concrete and pre-stressed reinforced concrete - Conceptualizing the structural layout of civil constructions such as buildings and bridges |
| Prerequisites |
The knowledge required to understand the course content and achieve the intended learning outcomes includes the following: Structural Mechanics: Fundamentals of Elasticity Theory and Energy Theorems; static analysis of statically determinate and indeterminate structures (force method). Structural Engineering: Theory of reinforced concrete and steel structures, both in the elastic and ultimate strength domains; design of basic structural elements in reinforced concrete and steel, with reference to serviceability and ultimate limit states as defined by current regulations. This knowledge is an essential prerequisite for students wishing to successfully follow the course. |
| Teaching methods |
The course is structured as follows: - Classroom lectures covering all course topics. - In-class presentation and solution of exercises in preparation for the written exam. - Optional office hours to support students in the development of assignments. |
| Learning verification modality |
The exam consists of a written test and an oral examination. The written test, lasting 2 hours, includes the solution of two exercises: one typically focused on influence line diagrams, and the other on a practical design or verification problem. The first part of the oral exam is a discussion of approximately 15 minutes aimed at assessing: i) the level of knowledge of the theoretical and methodological content of the course (Dublin Descriptor 1), ii) the ability to present technical solutions for the executive design of composite steel-concrete sections and pre-stressed reinforced concrete structures (Dublin Descriptor 2), iii) independent judgment (Dublin Descriptor 3) in selecting the most appropriate approach for each application context, with full awareness of the assumptions used in structural design and the physical meaning of the quantities involved. The oral exam will also assess the student’s communication skills, including proper use of technical language and the ability to independently structure their discussion on theoretical topics (Dublin Descriptor 4). The second part of the oral exam consists of a 15-minute presentation of group design work on a topic assigned by the instructor. During the discussion, students will describe the issues presented by the case study, justify their design choices (including alternatives), and explain the construction methods. The oral exam as a whole evaluates not only the student's knowledge and understanding, but also their ability to apply acquired skills, communicate effectively, and develop solutions with independent judgment. The final grade will be awarded on a scale of 30 points, with 15 points assigned to the written test and 15 points to the oral examination.

| Educational objectives |
The main objective of the course is to provide students with the theoretical knowledge and practical skills needed for the structural analysis and design of composite steel-concrete structural elements. The main areas of knowledge acquired (Dublin Descriptor 1) will include: - Methods for evaluating loads on structures - Theory of influence lines - Theory of composite steel-concrete structures - Basic concepts of the theory of concrete viscoelasticity . The main skills acquired (the ability to apply acquired knowledge—Dublin Descriptor 2—and to independently adopt appropriate approaches—Dublin Descriptor 3) will include: - Drawing influence lines for structural systems of varying complexity and using them to determine the most unfavorable load configurations; - Designing and graphically representing structural elements in reinforced concrete, prestressed reinforced concrete, and composite steel-concrete sections; - Conceptualizing the structural layout of civil constructions such as buildings and bridges. The module combines theoretical knowledge in structural mechanics with practical skills, including the ability to design civil structures and to produce detailed design reports and construction-level drawings |
| Prerequisites |
The following knowledge is required to understand the course content and achieve the intended learning objectives: • Structural Mechanics: Fundamentals of Elasticity Theory and Energy Theorems, static analysis of isostatic and hyperstatic structures (force method). • Structural Design: Theory of reinforced concrete and steel structures, both in the elastic and ultimate strength domains, and the design of basic structural elements in reinforced concrete and steel, with reference to serviceability and ultimate limit states as prescribed by current standards. This background knowledge is an essential prerequisite for students wishing to successfully follow the course. |

This part of the oral exam also evaluates the student’s communication skills, command of technical language, and ability to independently organize a coherent discussion of theoretical topics (Dublin Descriptor 4). The second part of the oral exam consists of a 15-minute presentation of technical-design work carried out in groups on a topic assigned by the instructor. During the discussion, students will explain the issues posed by the case study, justify the design choices made (including consideration of alternatives), and describe the proposed construction methods. Overall, the exam assesses the student's knowledge and understanding, ability to apply acquired skills, communication proficiency, learning capacity, and independent problem-solving ability. The final grade is expressed out of 30 points, with 15 points allocated to the written test and 15 points to the oral exam.
