3.) Benchmark variant studies of different problems of frame structures

Previous knowledge expected

The course builds on the scientific foundations imparted by the Bachelor’s program, and in particular on basic knowledge of:
(a) Mechanics
(b) Structural design and strength of materials
(c) Construction of framework structures

Objective (expected results of study and acquired competences)

Students will learn to break down the Finite Element Method into its constituents and to assess and evaluate the possible findings gained via this method.
