This course is run exclusively by the American Society of Civil Engineers (ASCE), the internationally recognised leader in training for engineers and technical professionals.
When wind, water, vehicles or earthquakes affect a structure such as a building or tower, the vibrations have the potential to make that structure unsafe. Excessive vibrations can lead to metal fatigue, poor operation of equipment within or on the structure, and even failure of the structure entirely.
This three-day course demonstrates a variety of methods for reducing excessive vibrations and places an emphasis on rotating equipment and foundations, earthquake analysis, blast loads, vibration isolation, structure-fluid systems and flow-induced vibrations.
On successful completion of the course you’ll have a better understanding of assumptions and limitations of various analysis techniques and guidelines on when to use which method; natural frequencies of simple and complex structures; structural response to dynamic loads and base excitations. You’ll also be able to design vibration absorbers, vibration isolators and foundations for rotating equipment, as well as troubleshoot and modify existing structures to reduce unacceptable levels of vibration.
You’ll receive a comprehensive set of notes and a textbook as reference materials.
You will benefit from this course if you’re an engineer or an engineering supervisor responsible for designing or qualifying structures and structural components subjected to dynamic forces.
It will also be highly useful if you’re involved in auditing, reviewing or approving vibration analysis tasks, no matter your level of experience.
C. Raj Sundararajan, Ph.D., M.ASCE has more than 37 years of experience in the analysis and design of structures subjected to dynamic forces. He is President of EDA Consultants (formerly known as Engineering Dynamic Associates). Previously he held senior technical positions at Lummus Company, Foster Wheeler Corporation and Impell Corporation.
Mr Sundararajan has taught short courses for practising engineers for more than 20 years.
He has a B.E. in Civil Engineering from the University of Madras, India, an M.E. in Civil Engineering from the Indian Institute of Science and a Ph.D. in Civil Engineering from the University of Waterloo, Canada.
Day one - structural vibration fundamentals
Day two - practical aspects of finite element modeling and analysis of vibration problems
This is not a course on finite element analysis, instead this course concentrates on the special aspects of modeling and analysing complex structures for vibration analysis. Advantages and disadvantages of different methods of analysis such as coupled and decoupled analysis, and time domain analysis and frequency domain analysis are discussed with guidelines on which methods are best suited for what types of problems. Guidelines for mesh size, cut-off frequency and time-steps are also presented.
Synthesis of analysis and test results
Structural response to earthquakes
Representation of base excitation

Day three - vibration absorbers
Designing for dynamic forces
Design aspects are discussed throughout the course. The different strategies of reducing vibration are summarised and relative merits discussed with practical examples.
