Subject Overview: This subject introduces students to the fundamental concepts of structural dynamics and finite element modelling and teaches students the basic skills of undertaking structural analysis in a practical engineering context. Topics covered include: introduction to finite element formulations for in-plane (membrane) stress analysis, three-dimensional stress and plate bending stress; use of finite element modelling packages; the response analyses of single-degree-of-freedom systems, discrete multi-degree-of-freedom systems and distributed mass (continuous) systems in conditions of natural vibrations and forced excitations; numerical time-step integration techniques; excitation simulation techniques, simultaneous equation solution and reduction techniques; optimal modelling techniques, frequency domain analyses and processing of time-series data. Skills acquired from the various topics outlined above will be integrated and applied to a number of case studies.
Objectives: At the end of this subject students should be able to
  • Implement the modelling of the response of single-degree-of-freedom (SDOF) systems to pulse and harmonic excitations
  • Describe and apply the concepts of viscous damping, hysteretic damping, coulomb damping (by friction) and equivalent damping
  • Implement time domain simulations of time histories of elastic responses
  • Implement the modelling of the response of discrete lumped mass multi-degree-of-freedom (SDOF) systems involving the use of the participation factor, effective modal mass and modal coefficients based on the principles of modal superposition
  • Implement the Rayleigh method in the dynamic analysis of structural systems with distributed mass
  • Obtain classical solutions for the dynamic response behaviour of single-degree-of-freedom (SDOF) systems based on harmonic excitations and common idealised forms of transient excitations
  • Implement on spreadsheets time-step integration procedures for analysing the response of SDOF systems to a range of transient excitations including earthquake excitations, and collation of the response output to produce elastic response spectra of different formats
  • Implement the synthesis of excitation time series including artificial accelerograms using existing software and seismological models, taking into account filtering effects of the soil medium and secondary linear systems
  • Implement on spreadsheets the response analyses of simple discrete MDOF systems using principles of modal superposition
  • Use finite element modelling packages to perform dynamic response analysis to a variety of dynamic loading options
  • Use finite element modelling packages to perform dynamic mode identification of principal modes of vibration of a variety of modelled structural systems
  • Transform data from time-domain to frequency domain in the form of Fourier Amplitude/Phase spectra and Power spectra, and apply linear transformation
  • Describe experimental modal analysis and its application in engineering practices
