Description including Unit Aims

By the end of this unit, successful students will be able to: understand the fundamentals of dynamic and seismic analysis of single and multi degree of freedom systems; derive the stiffness, load and mass matrices for simple structural finite elements; understand the operation of the important components of a finite element program; understand the characterisation of seismic loads; carry out a static and seismic analysis of a structure using a commercial computer programme.

Aims:

1. To introduce the concepts of single degree of freedom and multi-degree of freedom structural dynamics in the context of the analysis of structures subjected to seismic (i.e. earthquake) loading.
2. To extend the students knowledge of the Finite Element method by developing a general expression for the stiffness matrix and applying it to in-plane static and dynamic problems.

Intended Learning Outcomes

1. understand the fundamentals of the dynamic analysis of single degree of freedom (SDOF) systems; (PLO A1, A2, A4)
2. be able to calculate the response of SDOF systems to periodic and non-periodic forcing; (PLO A1, A2, A4)
3. understand the concept of generalized coordinates; (PLO A1, A2, A4)
4. be able to calculate frequencies of vibration and mode shapes for simple multi-degree of freedom systems and understand how to obtain the response of such systems to seismic and other types of forcing;
5. understand the concept of earthquake response spectra and their use in seismic analysis; (PLO A1, A2, A4, B2, B5)
6. be able to derive stiffness and mass matrices and load vectors for simple elastic truss and beam elements and to apply the finite element method to simple static and dynamic problems; (PLO A1, A2, A4, B2, B5)
7. be able to conduct a seismic response spectrum analysis of a multi degree of freedom system.
