Course abstract
Conditions for structural composition, model analysis methods of statically undeterminate systems (beams, trusses, frames) are gained. Methods for determination of internal forces in elements of statically indeterminate systems and system displacements, produced by external loads and temperature changes are acquired.
Learning outcomes and their assessment
Understanding of essential features of statically determinate and statically indeterminate systems. Skills to put into calculations a Force method for analysis of statically indeterminate systems. Test Nr. 1, Homework Nr. 1.
Skills to put into calculations a Displacement method for analysis of statically indeterminate systems. Test Nr. 2, Homework Nr. 2.
Competence to assess adequacy of results obtained.

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 and to verify the results by alternative approach. It is required positive assessment of two classroam tests and two homeworks. The course ends with examination including two calculation tasks in writing and one selected topic from theory (answer orally).
Description of the organization and tasks of students’ independent work
The first homework, 1st test. Analysis of statically indeterminate beam or frame by mean of Force Method.
The second homework, 2nd test. Analysis of statically indeterminate beam or frame by mean of Deflection 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 discuss on results of calculations and to verify the results by alternative approach. For each of three examination tasks 0-3 scoring points will be enrolled. Additional point (in case of existing 9 points) if student answer on additional question, not included in current examination tasks.
