| Learning outcomes and their assessment | |
| 1.Student knows the basic principles of mechanics and physics applied for design of structures; student is familiar with mechanical properties of structures regarding the main determinating parameters, their dimensions and limit values, – tests Nr 1 and 2. 2.Student is able to choose the calculation model according to actual, real structure; to formulate the design task, as well as to verify the results by means of alternate model calculations – workshops and homeworks. 3.Student is able to reasonable substantiate the calculation model choice and results credibility on the basis of the knowledge gained,- tests Nr 1 and 2 and homeworks | |

| Requirements for awarding credit points | |
| Credit test will be enrolled, if student know basic definitions of static, and he/she is able to discuss on results of calculations, to justify methods chosen and to prove the static equilibrium of internal and external forces. It is required positive assessment of tests. | |
| Description of the organization and tasks of students’ independent work | |
| 1st homework, 1st test. Beam or frame elastic displacement calculation. 2nd homework, 2nd test. Internal forces in members of statically undeterminate system - Force method or Displacements method. | |
| Criteria for Evaluating Learning Outcomes | |
| Student will have positive assessment of test, if at least 50% of calculation records are correct. The home work will be assessed basing on two criteria: 1) fulfilment of equilibrium conditions between internal and external forces and correct force diagramms; 2) ability to participate in conversation on calculations and results. | |
