Understanding Basic Dynamics – Modal to Time-step Analysis
£395.00
Featuring three live online sessions of 90 – 120 minutes each, this course is for engineers with a good understanding of linear analysis but who need to progress to dynamic analysis for design and assessment.
Many problems facing designers and engineers are dynamic in nature, whether it be vibration of a footbridge or impact of an object hitting a structure. While the assumption of linearity is routinely used for many designs with the application of dynamic load factors, sometimes a more refined – dynamic – approach is justified.
With LUSAS you can straightforwardly model the various forms of dynamic behaviour that can be encountered, and become proficient in using tools and facilities that are often seen to be the preserve of the experts.
Description
Obtain answers and practical engineering guidance to the following:
- Understand why you need to move from linear to dynamic analysis.
- Appreciate the fundamentals of dynamic analysis whether it is a modal vibration problem or a true time step analysis.
- Appreciate why modal analysis can be used to predict vibration modes of your structure (as long as the structure itself behaves in a linear way).
- Consider why nonlinear transient dynamic analysis can deal with boundary conditions, and why structural responses are nonlinear.
- Get an overview of the major application uses of dynamic analysis, from simple natural frequency calculations to time based seismic analysis and how to set them up in LUSAS
- Learn from practical dynamic examples including assessment of a footbridge due to footfall induced vibration considering codes of practice.
