Course content

The course looks at differences between structural design and structural analyses with a focus on the system level of design, exanimating structures as larger entities. Here we will examine selected topics within computational design of structures and structural systems. That is, the focus is on the digital design of structure with the use of fundamental mechanical knowledge (static and dynamic). Comparison between traditional design approach and the new methodologies, like parametric modeling, artificial intelligence, etc. is presented. Parametric modelling is explained in detail, also by the exercise done during the lectures. The following topics are also included: Analysis of construction systems and load carrying systems. Such as thin shells, lattice structures, bridges and in general long span structures are presented, designed and explained, 3D FE modelling of joints and influence of joint type on the global behavior of the structure, dynamic and serviceability issues in bridge design, buckling analysis. Every topic in the course will be based on the use of digital tools such as: AutoCAD, Dynamo, Robot or Abaqus. Note, changes may occur.

Learning outcome

TKT4198 is one of the last courses in student education at NTNU KT. Students during the whole are extensively using different types of software. The course covers Finite Element Analysis for objects such as: beams, shells, solids(only briefly).The course is explaining such method of design as: linear elastic analysis of big 3d structure, modal analysis, large displacement analysis, buckling analysis. The course focuses also on creating numerical models by new technologies. Parametric modelling, programming, algorithm aided design are used to generate computational models.

TKT4198 has these learning objectives:

Knowledge: The candidate should be able to explain FEA for structures with many elements. Student should be able by himself to decide which type of analysis have to use for specific task an boundary condition. Student should be able to use FEA in parametric modelling environment. Student should understand basic types of optimization methods.

Skills: The candidate should be able to perform different types of FEA in common FE software. Candidate should be using algorithm aided design in common CAD software. Candidate should be fluent in python scripting for optimization and modelling geometry of the structure.

General competence: The candidate should be able to explain and critically discuss the use of the finite element method in the analysis of structures. The student should be able to use visual programming and scripting to model and perform analysis.

Digital competence: Skilled use of finite element program (Autodesk Robot) for frame, truss, shell structures: Modeling, 1st and 2nd order analysis, buckling, modal, time-transient analysis and interpretation of results. Programming in AAD software (Autodesk Dynamo) with visual and classic scripting. Using python to perform optimization.

Sustainability competence: The course serves to give the students appropriate skills to design safe and cost-effective structures. The course is showing how they can optimize the structure towards weight, utilization, displacement and by this rationalize the LCA factors.

Learning methods and activities

The subject will be given by lectures, exercises and project. The project and 3/4 of the exercises must be approved in order to get admission to the exam. The lectures and exercises are in English when students who do not speak Norwegian take the course. If the teaching is given in English, the examination will be given in English only. Students are free to choose Norwegian or English for written assessments.
