Overview

After participating in this course, you will be able to:

  • Calculate dynamic loads from various types of machinery
  • Follow the decision process to select the type of foundation: shallow or pile
  • Build on your understanding of the dynamic response of tabletop structures for equipment support
  • Analyze dynamic response of various types of shallow and pile foundations
  • Apply the knowledge of analysis and design procedure for equipment foundation design and evaluate vibration damage and take suitable remedial measures

Description
The course considers loads induced by different machinery, modes of structural response of the foundation and/or supporting frame, as well as the response and damping provided by the soils. It covers fundamentals of machine dynamics for derivation of the applied loads, behaviour of types of rigid block and pile-supported foundations, analysis and design of tabletop structures for equipment support, machine foundations on frozen soils, vibration damage assessment and prevention. It will start with the concepts and practical “rules of thumb” used in preliminary layout and sizing of the foundations and focus on explanation and demystifying of the basic concepts, relating them to the first principles of engineering.

You will be able to design equipment foundations using hand techniques, common finite element packages as well as specialized software (DYNA 6).

Course Outline:

  • Intro to design of equipment foundations
  • Method of dynamic impedance
  • Dynamic soil properties
  • Design of shallow and pile foundations
  • Determination of loads from types of machinery
  • Dynamic response of impact and vibratory machinery foundations
  • Vibration damage and suitable remedial measures
  • Tabletop structures
  • Dynamically loaded foundations on frozen soils
  • Methods of analysis and design examples

Who Should Attend:
Consulting Engineers (Civil and Structural) who must analyze and design equipment foundations and wish to acquire advanced knowledge and practical design skills

Special Features:
This is an advanced course targeting skilled designers who want to learn how to solve complex design problems with full understanding of the structural behaviour. The access to a laptop computer during the seminar is not essential. Participants will work on several examples under instructor guidance.
