Further information on descriptions Description: Aims:
To cover the effects of vibrations, dynamics, wind and earthquake affecting the behaviour and stability of structures.

Learning Outcomes:
On successful completion of the unit, the student will be able to analyse complex structures in terms of dynamics and stability. The student will also be able to demonstrate:
* a systematic understanding of this knowledge, and a critical awareness of current problems and/or new insights, much of which is at, or informed by, the forefront of this area of professional practice;
* conceptual understanding that enables the student to evaluate critically current practice and new developments, and propose new solutions;
* an ability to deal with complex issues both systematically and creatively, make sound judgements in the absence of complete data, and communicate their conclusions clearly.

Intellectual skills
* To understand taught material - taught
Professional/Practical skills
* To understand vibrations, dynamics, wind and earthquake affecting the behaviour and stability of structures - assessed.
Transferable/key skills
* To communicate ideas verbally and in writing - facilitated and assessed.

Modal analysis for vibrations and buckling of structures; eigenvalues, eigenvectors and othogonality conditions. Damping and geometric stiffness. Lateral vibrations of beams under constant axial load. Discussion of post buckled stability via single degree of freedom models. Lateral torsional buckling of beams. The nature of wind, flow around angular, curved and streamlined bodies. Vorticity and turbulence. The effect of terrain. Introduction to the statistics of extremes, return periods, gusts, etc.. Introduction to codes and standards. Wind tunnel testing. Comfort criteria limiting sway of tall buildings. Introduction to aero-elasticity, flutter, galloping and divergence. Aero elastic wind tunnel tests. The causes of earthquakes, prediction of ground movements. Effects of earthquakes on buildings and other structures. Introduction to codes and standards.
