Advanced Structural Dynamics, Modelling and Measurements

Course credits: 7.5 ECTS

Description

The course gives a deeper insight into the theory and methods for the analysis of dynamically loaded structures and demonstrates the possibilities of using modelling and field measurements to access the behaviour of existing structures.

Content and Objectives

The aims of the course are to give
  • Additional knowledge on the behaviour of structural elements acted on by dynamic loads
  • Knowledge on dynamic vehicle-structure interaction
  • Knowledge on dynamic soil-structure interaction
  • Knowledge on how to use field measurements to access structures
  • Knowledge on signal analysis
  • How to model structural elements so that they could be accessed by field measurements.

Prerequisites

  • Academic degree in civil engineering.
  • Passed courses in basic finite element theory.
  • Passed basic courses in structural dynamics.
  • Experience in MATLAB programming.

Attendance

Graduate students, teachers and researchers in structural engineering
Practising structural engineers, wanting to learn about assessment of structures, vehicle-structure-soil interaction and analysis of measured signals.

The courses are primarily designed for PhD students at technical universities and to some extent civil engineering students in late stages of education. Many of the courses can also be of great interest for professionals in the building and civil engineering sector as a part of specialist training.

Course plan

The course will be given in two concentrated blocks in June and August 2015 with lectures and one field test. Lectures and presentations will be given in English. Apart from the scheduled teaching, the participants are expected to do independent home work in the form of analytical problem solving, computer based exercises and a written project report/paper. The course venue is The Royal institute of Technology (KTH), Department for civil and architectural engineering. The field test will be performed on a pedestrian bridge in Stockholm, KTH.

Course organisation

Responsible teaching staff and lecturers are:
  • Raid Karoumi and Costin Pacoste (experts on FE-modelling and measurements from KTH)
  • Anders Brandt and Rune Brincker (experts on dynamic measurement and signal analysis from SDU, Denmark)
  • Participating students.

Examination

The course corresponds to 7,5 ECTS credits. To pass the course the student must perform the homeworks and a project task. All must be documented and accepted. At least 80 % participation on the course is needed. The student will get the grade pass or not pass.
