Goal

The purpose of teaching the course "Resistance of materials and structural mechanics" is to teach students the geometric properties of their motion without taking into account the inertia of bodies and forces, to establish the laws of motion of material bodies taking into account inertia. forces and efforts, deformation of elastic bodies under the influence of external forces, theoretical knowledge on the calculation of strength, rigidity and stability of structural elements.

Objective

The task of teaching the discipline is to apply theoretical knowledge to solve practical problems that arise in the design of buildings and structural elements.

Learning outcome: knowledge and understanding

Knowledge of the basic methods and principles for calculating the strength and stiffness of building elements, as well as recommendations for the effective design of engineering structures.

Learning outcome: applying knowledge and understanding

- Knowing the laws of motion of a given body (or point), determine the movement of the body as a whole, as well as all the kinematic dimensions characterizing the movement of each of its points individually (trajectory, speed, acceleration, etc.). - Apply basic laws and theorems to solve applied problems. - Be able to perform calculations of strength, stiffness and stability of structural elements under simple types of deformation (tension-compression, torsion in statically specified systems), complex deformations (transverse bending, off-center compression), including using modern software tools.

Learning outcome: formation of judgments

Each student must have a well-formed judgment on the topic of his specialty.

Learning outcome: communicative abilities

Conduct a conversation- dialogue in any language, use the rules of speech etiquette.

Learning outcome: learning skills or learning abilities

To form in the conditions of real production the principles of choosing the directions of optimization of technologies and properties of materials products and structures.

Teaching methods

- Interactive lecture (application of the following active forms of learning: guided discussion or conversation; moderation; demonstration of slides or educational films;) - construction of scenarios for the development of various situations based on the specified conditions; - information and communication; - search and research (independent research activity of students in the learning process); - solving educational tasks.

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	No. 1 Computational and graphical work is a complex resistance. Oblique bend.	0-100
	No. 2 Computational and graphical work is a complex resistance. Off-center compression and stretching
	Milestone test 1
2 rating	No. 3 Calculation and graphic work - Calculation of flat statically definable frames.	0-100
	No. 4 Calculation and graphic work - Calculation of a multi-span beam
	Milestone test 2
Total control	Exam	0-100

The evaluating policy of learning outcomes by work type

Type of task	90-100	70-89	50-69	0-49
Type of task	Excellent	Good	Satisfactory	Unsatisfactory
Working in practical classes	Completed the practical work in full with the necessary sequence of actions; in response, correctly and accurately performs all records, tables, drawings, drawings, graphs, calculations; correctly performs error analysis.	I fulfilled the requirements for the "5" rating, but 2-3 shortcomings were made. The student's answer to the questions satisfies the basic requirements for answering 5, but is given without applying knowledge in a new situation, without using connections with previously studied material and material learned in the study of other disciplines.	I did not complete the work completely, but at least 50% of the volume of practical work, which allows me to get the right results and conclusions; mistakes were made during the work.	Completed the practical work in full with the necessary sequence of actions; in response, correctly and accurately performs all records, tables, drawings, drawings, graphs, calculations; correctly performs error analysis.

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	Excellent
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	Unsatisfactory
