2. Célkitűzések és tanulási eredmények
2.1 Célkitűzések
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.

A félév közbeni munkaszüneti napok miatt a program csak tájékoztató jellegű, a pontos időpontokat a tárgy honlapján elérhető "Részletes féléves ütemterv" tartalmazza.
2.5 Tanulástámogató anyagok
a) Online materials:
  • Downloadable abstracts based on Kollár, L.P.: Basis of structural design, 2015
2.6 Egyéb tudnivalók
  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 Konzultációs lehetőségek
  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
