Course abstract

The course is aimed to acquiring some skills for computer-aided design of timber frame houses and blockhouses as well using SEMA Software. Students have been acquainted with the main program modules enable for planning the house according to the initial data and architectural conception, and requirements of customer as well, module of structural analysis, fasteners and joining of elements correspondingly to actions predicted, construction materials and technological tools available. After completition of the study course student will have some skills for computer-aided design of timber houses and he/she enable for assessment of advantages and limitations as well

Learning outcomes and their assessment

After completing the course student will have:
• knowledge and understanding the scope of SEMA Software meaning method of structural analysis and Eurocode conditions covered;
• skills: for design of timber frame house or blockhouse by SEMA Software tools;
• competencies: for evaluation of quality of design project regarding to function of building, actions, materials and technologies available as well
