Goal
- Formation of theoretical basis for students to understand the calculation methods for strength, rigidity and stability of elements of structures and constructions, ensuring its reliability and efficiency; development of engineering thinking and acquisition of knowledge necessary for the study of subsequent disciplines.
Objective
- Mastery of the concepts and definitions outlined in the course of the discipline; study of the methods necessary to investigate practical and theoretical issues of science and technology; acquisition of skills to calculate the elements of buildings and structures for strength, rigidity and stability; study of the mechanical properties of structural materials.
Learning outcome: knowledge and understanding
- The student must know and understand the methods of calculation of structural elements and issues of calculation of some simple structures; modern methods of calculation of bending, the method of calculation of statically determined and indeterminable problems on examples of calculation of flat rod models; determination of internal forces, stresses, strains and displacements in structural elements.
Learning outcome: applying knowledge and understanding
- Apply the acquired knowledge in practice; perform strength calculations for various types of body loading; choose different schemes when assessing the strength of real structures.
Learning outcome: formation of judgments
- Possess a formed judgment on the topic of their specialty.
Learning outcome: communicative abilities
- Lead a conversation-dialogue, use the rules of speech etiquette.
Learning outcome: learning skills or learning abilities
- Have the skills to apply the acquired knowledge to practical calculations.
Teaching methods
Interactive lecture (discussion or conversation; moderation; demonstration of slides or educational films); building scenarios of various situations based on given conditions; information and communication; search and research (independent research activity of students in the learning process); problem solving.
Assessment of the student's knowledge
Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.
| Period | Type of task | Total |
|---|---|---|
| 1 rating | Input control. Elements of vector algebra and projections of forces on coordinate axes. | 0-100 |
| Problems on "System of Converging Forces". Determination of the bracket bonding reactions. | ||

The evaluating policy of learning outcomes by work type
| Type of task | 90-100 | 70-89 | 50-69 | 0-49 |
|---|---|---|---|---|
| Excellent | Good | Satisfactory | Unsatisfactory |
Evaluation form
The student's final grade in the course is calculated on a 100 point grading scale, it includes:
- 40% of the examination result;
- 60% of current control result.
The final grade is calculated by the formula:
| FG = 0,6 | MT1+MT2 | +0,4E |
| 2 |
Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;
E is a digital equivalent of the exam grade.
Final alphabetical grade and its equivalent in points:
The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
| Alphabetical grade | Numerical value | Points (%) | Traditional grade |
|---|---|---|---|
| A | 4.0 | 95-100 | Excellent |
| A- | 3.67 | 90-94 | |
| B+ | 3.33 | 85-89 | Good |
| B | 3.0 | 80-84 | |
| B- | 2.67 | 75-79 | |
| C+ | 2.33 | 70-74 | |
| C | 2.0 | 65-69 | Satisfactory |
| C- | 1.67 | 60-64 | |
| D+ | 1.33 | 55-59 | |
| D | 1.0 | 50-54 | |
| FX | 0.5 | 25-49 | Unsatisfactory |
| F | 0 | 0-24 |
