In the past 20 years, there has been a major advancement in the seismic design of reinforced concrete mat foundations. The mathematical modeling of these continuous structural elements has led to seemingly more precise designs as analytical capabilities have progressed, mainly through the use of finite element analysis. However, basic concerns about these thick foundation systems' seismic performance still exist.

For a structural engineer to move forward with a seismic design in an informed manner, this course aims to address the known and unknown aspects of this subject. Designs that take this unpredictability into account are encouraged, as many of the characteristics related to a mat foundation design can be highly changeable.

Learning Objectives

Upon completion of this course, participants will be able to:

• Identify the parameters needed from a geotechnical engineer for mat-foundation design.
• Define the soil parameters used in mat-foundation design.
• Explain general soil-structure interaction principles.
• Describe the backstay effect.
• Perform proportioning for bearing pressure, punching shear, and sliding.
• Analyze a mat foundation using typical modeling practices, analysis options, iteration with the geotechnical engineer, and sensitivity analysis.
• Explain the behavior and design considerations of mats supported on deep foundation elements.
• Detail a mat foundation in accordance with the course requirements.

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 14 questions. CPD credits are not awarded until the course is completed and quiz is passed.
