10/13/20 | ACI 360 – Design of Slabs on Ground | Scott Tarr, PE, FACI (North S.Tarr Concrete Consulting) | 2 Hours |
There are five commonly used procedures for designing industrial floor s… There are five commonly used procedures for designing industrial floor slabs. All of them are effective when their recommendations and details are followed. So, how does a designer choose the best method for a particular floor? The most common approach is to determine the type of floor construction needed for expected loading conditions. Then, from the design procedures, select the most appropriate method for determining floor thickness, reinforcement, joint spacing, and other details. This presentation will discuss the ACI 360 “Guide to Design of Slabs on Ground”. It will briefly address 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. Some worked design examples for various types of concrete slabs-on-ground will also be covered. |

2/23/21 | Avoiding Damage, Distress, and Disappointment in Concrete Structures | Michael W. Lee (Principal at Wiss, Janney, Elstner Associates) | 1 Hour |
This presentation reviews failures, damages, and other incidences of poo… This presentation reviews failures, damages, and other incidences of poor performance in concrete structures that have served to shape today's building codes and the standard of care for the profession. Examples range from well-documented, high-profile collapses to lesser known but similarly influential structural and serviceability problems. Case histories will include discussion of excessive cracking, the cause of such distress, and mitigation measures. The case histories will illustrate how small details can often mean the difference between success and disappointment; and how codes have evolved to reduce the risk of future failures. |

The work shows that during pumping the air volume will decrease and if measured immediately after pumping will be lower than what is found in the final concrete. These findings are supported by hardened air void analysis, freeze thaw tests, and measurement of the air void volume and spacing over time in the fresh concrete with the Super Air Meter. The presentation makes recommendations for modifications to the current testing specifications based on the findings. |
