Slab on Ground Design Workshop (1.2 CEUs)

Daily Schedule:
8:30am - Session begins
11:30am - Adjournment
 
This course is divided into four sessions. Each session will be 3 hours in duration. The sessions will be held on September 23, 24, 30 & October 1.
 
If you are unable to attend any of the sessions a recording will be made available.
 
Description
This course is a practical structural design course that contains step-by-step procedures that include instructions that help understand and design for slab on ground. This course presents information on the design of slabs-on-ground, primarily industrial floors. The course addresses the planning, design, and detailing of slabs. Background information on design theories is followed by discussion of the types of slabs, soil-support systems, loadings, and jointing. Design methods are given for unreinforced concrete, reinforced concrete, shrinkage-compensating concrete, post-tensioned concrete and fiberreinforced concrete slabs-on-ground, followed by information on shrinkage and curling problems. Advantages and disadvantages of each of these slab designs are provided, including the ability of some slab designs to minimize cracking and curling more than others. Several design methodology will be introduced including the ACI design methodology.  Examples using several design methods are also provided.
 
Objectives:
This course will provide the participants with an understanding of the subgrade drag theory and how it relates to the reinforcing of slab-on-grades as required to help control shrinkage cracking. Two other alternate design methods are also discussed relative to the sizing of "distribution" slab-on-grade reinforcement. Different types of reinforcing materials are also discussed including welded wire fabric, conventional deformed reinforcing bars and post-tensioning tendons.

Target Audience
  • Structural site Engineers and even design Engineers needing to refresh their design skills according to the new building code and design standards
  • Structural contractors wanting to know how the structures they erect are designed
  • Structural draftsmen wanting to know how the structures they draw are designed
  • Architects and non-structural engineers such as Mechanical, Electrical and Plant Engineers interested in upgrading their knowledge and skills in the area of structural design

Learning Outcomes
This course will introduce you to the current codes and standards that govern structural design of slab on ground, including the structural provisions of the ACI . You will also learn:

  • Basic understanding of codes and design methods.
  • This course will enable the user to become familiar with the following methods of designing slab-on-ground:
    • PCA method

Dr. Abdelaziz has served as a senior geotechnical engineer at DST Consulting engineers, Sarafinchin Consulting engineers, Trow Consulting and EBA engineering. Currently he is the managing director of SAGA Engineering, Edmonton, AB, Canada. 

Dr. Abdelaziz has over 32 years of experience in geotechnical and structural engineering, foundation design, teaching, research and consulting in Canada and overseas.

Dr. Gamal has designed and delivered over one hundred geotechnical engineering workshops which are very well received by practitioners engineers in Canada and globally.

Currently he is a senior geotechnical engineer with SAGA Engineering, Edmonton, Alberta. His duties include revision of geotechnical design, including slope stability, foundation and machine foundation design, soil investigation, design of cuts and earthfills, evaluation of stability of existing slopes, slope reinforcement using geotextiles, geogrids, soil nails, base reinforcement to support earthfills on soft subgrade soils, Erosion protection using geocells matting, rip rap, stabilization of unstable slopes, evaluation of soil bearing capacity to support footing foundations, Settlement studies, deep foundations including driven piles, auger injected (CFA) piles, additional support to existing foundations by underpinning utilizing concrete panels, grouting, micropiles, evaluation of earth pressures on retaining walls, security of excavation base, tieback support, etc.

Dr. Abdelaziz is a former adjunct professor at University of Western Ontario, London, Ontario, Canada, visiting professor at Ryerson University, Toronto, Canada and part time professor at Seneca College, Toronto, Canada.

Dr. Abdelaziz is specialized in numerical modeling for solving sophisticated geotechnical engineering problems with respect to pile foundation and the linear and nonlinear analysis of soil-structure interaction. He designed charts to predict pressures acting on tunnels, and developed an analytical model for pile bearing capacity prediction.

Dr. Abdelaziz authored a number of technical papers and delivered numerous internal and external workshops on various geotechnical and Municipal engineering topics. Dr. Abdelaziz has been involved in a number of projects in Canada and overseas, such as tunneling, silos, buildings, retaining structures, siphons, irrigation networks and many other civil engineering projects in terms of design and construction.

Concrete slabs-on-ground are highly susceptible to cracking due to shrinkage. Construction and control joints are typically used to control crack location. Since it is not always desirable or practical to use a large number of closely spaced joints, reinforcing of the slab-on-grade allows for greater flexibility with joint spacing. Welded wire mesh or deformed bar reinforcement normally used in slabs-on-ground helps to control the width or growth of any cracks that may occur. This type of steel is sometimes called distribution reinforcement to differentiate it from structural reinforcement that is added to increase the load-carrying capacity of the slab.

Education @ Your Desk. A Live Webinar Class means that you will attend the class via the web using your computer. There are scheduled breaks for coffee and lunch. You use a microphone, headset, or your phone and are able to interact with the instructor and other students while following notes while watching the presentation slides online just as you would in a live classroom. Notes are posted online. For an extra cost a hard copy can be requested.

The virtual classroom is becoming more and more popular, and we have a lot of experience teaching in this format. The only real difference between a live in-class and live via webinar is where you sit and what you look at. You can learn from the comfort of your own home or office. You pay less for the live webinar format than you would for the in-class format, and you do not have to travel to another city to attend the class. Please contact us at gic@gic-edu.com for Special Group & Corporate Rates for one or more participants.

We could offer any of our courses at a location of your choice and customized contents according to your needs, please contact us at : inhouse@gic-edu.com or click here  to submit an online request.
