The short course and workshop should be of interest to geotechnical engineers and civil engineers who wish to have a better understanding of the current state-of-the-art with respect to the analysis and design of flexible, rigid and pile foundations subjected to all types of dynamic loads.  All key concepts and terminology will be explained and emphasis will be placed on the practical application of the information provided.   Objectives
To develop understanding of the concepts, theories and procedures of design of foundations subjected to dynamic loads.  The participants will learn to calculate the stiffness and damping constants of different types of foundations.  They will also learn to calculate the response of these foundations under the effect of different types of dynamic loading.   Description
Soil dynamics is the branch of soil mechanics that deals with the behaviour of soil under dynamic loads.  Different types of foundations are used to support structures subjected to dynamic loads or vibration producing machines.  This course will focus on the analysis and design of these foundations.  Topics to be discussed include:  
  • Introduction
    Design objectives, design procedure, basic notions, mathematical models, DOFs, types of dynamic loads, foundation types, excitation forces of machines, dynamic soil properties.
  • Shallow Foundations
    Definition of stiffness, damping and inertia, circular shallow foundation, non-circular foundation, embedded footings, impedance functions of a layer on half-space.
  • Pile Foundations
    Pile applications, mathematical models for pile analysis, stiffness and damping of piles, pile groups, interaction factors, impedance functions of pile groups, pile batter.
  • Dynamic Response of Machine Foundations
    Response of rigid foundations in 1 DOF, effects of vibration, response of rigid foundations in 2 DOF and 6 DOF, response of structures on flexible foundations.
  • Dynamic Response of Hammer Foundations
    Types of hammers and hammer foundations, design criteria, mathematical models, impact forces, response of one and two mass foundations, impact eccentricity.
  • Vibration Damage and Remedial Measures
    Damage and disturbance, problem assessment and evaluation, remedial principles, examples from different industries, sources of error.
  • Computer Workshop –DYNA5
    Types of foundations, types of soil models, types of load, types of analysis and types of output, practical considerations, computer work on DYNA5.

Who Should Attend
Structural engineers, civil engineers, public works and construction department employees of federal, provincial and municipal governments and engineers responsible for large industrial, commercial or institutional facilities who must deal with different types of foundations.

The course will be of interest to a wide range of practising civil engineers at different stages in their careers. Some familiarisation with soil mechanics is desirable but the knowledge is not required at a specialist level.

Expected Outcome
After Participating In The Course, You Will Be Able To:

  • Judge what foundation system should be considered in the design.
  • Recognize the important aspects of foundation dynamic behaviour; and the limitations of different models used for dynamic analysis of foundations.
  • Determine the stiffness and damping constants of shallow and deep foundations.
  • Calculate the response of shallow and deep foundations to dynamic loads.
  • Find the natural frequencies of foundation systems.
  • Specify suitable field and laboratory investigation programs for foundations subjected to dynamic loads.
  • Use DYNA5 for shallow and deep foundation systems.
  • Develop modelling skills for design of foundations subjected to dynamic loads.
  • Achieve confidence in the design of foundations subjected to dynamic loads.
