2. Objectives and learning outcomes
2.1 Objectives
The goal of the subject is to get students to know the modeling possibilities of rod structures appearing in the structural engineering practice, the theoretical background of the models. Based on the linear mechanical model of the generalized beam element students will be acquainted with the calculation of the stiffness matrix and load vector of frame structures and their generalizations e.g. trusses, grids, and infilled frames. Higher-order analysis of kinematically indeterminate structures with high importance in engineering practice will be learnt.
2.2 Learning outcomes
Upon successful completion of this subject, the student:
A. Knowledge
  1. knows the matrix-algebraic description of the static and geomatric state of a cantilever beam of linear elastic material with arbitrary axis and cross-section,
  2. knows the meaning and the calculation method of the stiffnes matrix and equivalent load vector both of the element and of the structure,
  3. is familiar with the consideration of eccentric and partial connections,
  4. is familiar with the consideration of rigid and elastic supports,
  5. knows the simplified models of special structure types,
  6. understands the use of variational principles for the calculation of simple models,
  7. is familiar with the modeling possibilities of infilled frames,
  8. understands algorithms for the calculation of the shape of cable-stayed bridges and cable nets,
B. Skills
  1. calculates the internal forces and displacements of a linear, prismatic, cantilever beam with the application of transmission matrices,
  2. calculates the entries of a stiffness matrix of a beam member with special connection,
  3. calculates the stiffness matrix and the equivalent load vector of frame structures, and considers the support conditions,
  4. uses a simplified model reflecting the specialities of the mechanical problem,
  5. calculates the displacements of beams on elastic foundation,
  6. calculates the equilibrium shape of kinematically indeterminate bar-and-joint assemblies for a given load,
C. Attitudes
  1. endeavors to discover and routinely use the tools necessary to the problem solving in structural mechanical,
  2. endeavors to the precise and error-free problem solving,
  3. aspires to prepare a well-organized documentation in writings, and pursues the precise self-expression in oral communication,
D. Autonomy and Responsibility
  1. independently carries out the conceptual and numerical analysis of structural engineering problems, based on the literature,
  2. is open to accept well-founded critical comments.

II. Subject requirements

Assessment and evaluation of the learning outcomes
3.1 General rules
  • Evaluation of learning outcomes described in Section 2.2. is based on two mid-term written checks.
  • The duration of each mid-term test is 90 minutes.
  • The dates of checks and the deadlines of homeworks can be found in the "Detailed semester schedule" on the website of the subject.
3.2 Assessment methods
Evaluation formAbbreviationAssessed learning outcomes

3.3 Evaluation system
3.4 Requirements and validity of signature
There is no signature from the subject.
3.5 Grading system
  • A minimum presence of 70% is required to gain a signature
  • In the case of complying with the requirements on attendance the results are determined as follows.
  • Mid-term test result below 50% considered as unsuccessful.
  • Both mid-term test must have a successful result to gain a semester mark.
  • The semester result is computed by the weighted average A of the mid-term tests, as in section 3.3.:
GradePoints (P)
excellent (5)80%≤A
good (4)70%≤A<80%
satisfactory (3)60%≤A<70%
passed (2)50%≤A<60%
failed (1)A<50%
3.6 Retake and repeat
  • In this subject each mid-term test can be retaken once. From the results of the original test and the retake the best counts.
  • There is no second retake in this subject.
