Course goals and learning objectives
The purpose of the course is to provide knowledge about calculations of building structures by finite elements method for static and dynamic types of load, creation of discrete calculation models of structures and analysis of their behavior, as well as methods of automated calculation and construction of elements of structures on the example of the software complex LIRA-SAPR.
Course objective:
- to acquaint students with the basics of the finite element method for the analysis of the stress-strain state of structures;
- develop skills of application of modern software for automation of calculation, research and design of building structures;
- master the basic methods and techniques of the formation of discrete calculation schemes of building structures, their calculation on different types of static loads, temperature, deformation and dynamic actions.
