Concrete floor slabs on grade are often subjected to heavy loads in buildings such as wall loads, stationary live loads and moving loads. A common example of a moving load would be a forklift used in a warehouse. Stationary live loads are imposed by movable items such as stored materials. Concrete floor slabs on grade supporting such loads have to be designed so that cracking, settlement and stresses are minimized.

During the design process for heavy duty concrete slabs, several variables need to be considered such as floor slab loads, subgrade conditions, steel reinforcement requirements, joint types, and environmental conditions. This course will provide the student with the criteria needed to design concrete floor slabs on grade subjected to heavy loads. Design examples are shown to aid in understanding the course material.

Learning Objectives

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

• Define light and heavy slab loading and identify the subgrade, reinforcement, and joint variables that govern slab-on-grade performance.
• Determine the modulus of subgrade reaction, dowel length, slab thickness, and joint spacing for representative heavy-duty floor-slab conditions.
• Analyze the effects of reinforcing steel, dowels, tie bars, keyed joints, and thickened slabs on cracking and load transfer.
• Design a conceptual jointing and reinforcement strategy to control cracking, faulting, and shear stresses in a heavy-duty slab.

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 20 questions. CPD credits are not awarded until the course is completed and quiz is passed.
