Prerequisite Modules:
Rationale and Purpose of the Module:
To develop an understanding of the role of dynamics in structural design and provide an introduction to the analysis and design of structures subjected to seismically induced loading.
Syllabus:
Dynamic response of single degree of freedom (SDOF) systems - free response, damping, resonance, forced vibration; Energy methods, springs in series and in parallel, lumped mass and stiffness models with multiple degrees of freedom (MDOF), mass and stiffness matrices for shear buildings, mode shapes, natural frequencies of vibration, harmonic base excitation; Earthquake response and design spectra; Linear and nonlinear response to earthquake loading for SDOF systems; Earthquake response of lumped mass/stiffness MDOF systems; generalised co-ordinates method, mode superposition method; Relevant provisions of Eurocode 8 (Design of Structures for Earthquake Resistance).
Learning Outcomes:
Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)
Determine the natural frequency and free-vibration response of a SDOF building /system, Determine the forced-vibration response of a SDOF building /system to harmonic or base excitation e.g. earthquake ground motion; Describe the origin of seismic loads and their effect on building structures; Draw design spectra for linear and nonlinear structures; Develop a lumped mass and stiffness MDOF model to represent a simple building and hence determine its natural frequencies and mode shapes when undergoing synchronous motion; Determine the peak force and displacement responses of such a building under earthquake loading given details of the relevant response spectrum; Apply the provisions of Eurocode 8 to structural design.
Affective (Attitudes and Values)
None
Psychomotor (Physical Skills)
None
How the Module will be Taught and what will be the Learning Experiences of the Students:
Module will be taught using formal lectures. Concepts presented will be reinforced with assigned tutorial work. Students will learn to apply the provisions of Eurocode 8 through a design project carried out in teams in parallel with lectures.
