2. Objectives and learning outcomes
2.1 Objectives
The primary aim of the course is to provide the students with basic knowledge on the process of civil engineering design and the structural behaviour. During the semester the following topics are discussed: engineering design, structural design process and methodology, hierarchic and spatial structures; modelling of structures (structural model); probabilistic background of structural design, partial (safety) factor method; actions on structures, selection of critical load case, design load; internal stress and strain, material laws, elastic and plastic resistance; analysis methods, geometrically linear and nonlinear analysis, linear and nonlinear material behaviour, superposition; limit states (ULS&SLS), structural failure modes; design of structural members (beams and columns), design of structures for horizontal actions; bracing systems; selection of structural form and material, thrust line; spatial structures; classification of structures according to their form and static behaviour.

The above programme is tentative and subject to changes due to calendar variations and other reasons specific to the actual semester. Consult the effective detailed course schedule of the course on the subject website.
2.5 Study materials
a) Online materials:
  • Downloadable abstracts based on Kollár, L.P.: Basis of structural design, 2015
2.6 Other information
  1. Homework contain short tasks with the aim to give help preparing for the tests rather than providing new knowledge. Solutions will be available immediately after the relevant submission deadline before the relevant test. In order to model test conditions, the solution shall be hand-written without using any software (e.g. Mathcad).
  2. Numerical results of homework shall be submitted in electronic form (upload of results through the website of the subject), furthermore, the hand-written solution (in scanned or photo form) shall be submitted until the relevant deadline. Any homework is considered to be completed if BOTH submissions have been successful.
  3. Hand-written submission shall contain the solution of all tasks including formulae, substitutions as well as numerical results equal to those uploaded electronically (see details in homework) and dimensions.
  4. Submission of tests is conditional on showing an identity document including photo and signature at the beginning of the test.
2.7 Consultation
  1. Joint consultations before each test to help preparing for the tests are organized outside the official schedule. Attendance on these consultations are optional.
  2. The instructors are available for consultation during their office hours, as advertised on the department website. Special appointments can be requested via e-mail: kovacs.tamas@epito.bme.hu

3.3 Evaluation system
Abbreviation Score
T1-T3 82%
HW1 6%
HW2 6%
HW3 6%
Sum 100%
Extra points (for those, who have already fulfilled 50% out of T1&T2 and complete T3 above 50%) equal to 10% of the lowest test result (out of Test#1, #2 and #3) and limited to a maximum of 8. 8%
3.4 Requirements and validity of signature
Attendance on at least 70% of lectures.
3.5 Grading system
Conditions to receive grade:
  • Average of the best two total results out of those obtained from Tests#1, #2 and #3 (three results) shall be at least 50%.
  • Average of the best two results of theoretical test parts out of those obtained from Tests#1, #2 and #3 (three results) shall be at least 40%.
  • Obtaining at least a total of 45 points according to clause 3.3 above.
The final grade is determined as follows:
Grade Points (P)
excellent (5) 90<=P
good (4) 75<=P<90%
satisfactory (3) 60<=P<75%
passed (2) 45<=P<60%
failed (1) P<45%
3.6 Retake and repeat
There is no minimum requirement for individual midterm tests, therefore no possibility for individual retake of tests is available
3.7 Estimated workload
Total: 3 credits × 30 hours/credits = 90 hours/semester.
