Goal
- Mastering by students of the basic provisions on rational design and calculation of various types of structures made of wood and plastics, practical application of modern measures to protect wooden structures from rotting and fire, familiarity with the features of the technology of manufacturing and installation of structures, as well as the development of skills of independent work with scientific and technical literature on construction.
Objective
- Study of the basic physical and mechanical properties of wood and structural plastics; rules for the design and calculation of structures made of wood and plastics.
Learning outcome: knowledge and understanding
- Features of work and calculation of wooden structures of one-story industrial, public and residential buildings.
Learning outcome: applying knowledge and understanding
- In specialized software and computer systems (PCS SCAD, Tekla, Revit) to design and construct wooden structures of one-story industrial, public and residential buildings in accordance with current regulatory documents.
Learning outcome: formation of judgments
- Know the requirements for the structure and composition of project documentation at the stages of design, calculation and construction.
Learning outcome: communicative abilities
- Knowledge of the regulatory framework in the field of engineering surveys, principles of designing buildings, structures, planning and development of populated areas.
Learning outcome: learning skills or learning abilities
- Graphics skills editors to carry out the design documentation
Teaching methods
Traditional technologies are provided for teaching: classroom lessons and independent work of students. The lecture course is presented in a multimedia form. When presenting lecture material at the beginning and at the end of the lecture, motivational speech is used. Text, audio and video information, graphs, tables, etc. are used in the lecture-presentation and practical exercises.
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 | Calculation of wooden structures for tension and compression | 0-100 |
| Calculation of wooden structures for bending and oblique bending | ||
| Calculation of compressed-bent elements of wooden structures | ||
| 2 rating | Calculation of tensile-bent wooden elements structures | 0-100 |
| Calculation of connections of elements of wooden structures | ||
| Calculation of decking, calculation of runs | ||
| 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 |
|---|---|---|---|---|
| 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 |
