This live web event has ended. Thank you for attending.


The design of slender concrete walls out-of-plane, also known as tilt-up construction, is based on a combination of theoretical and experimental evidence; however, the concepts behind the provisions in ACI 318 are often misunderstood and sometimes improperly applied. This presentation will explain the basis of many of the provisions with some seismic design examples. Additionally, the importance of out-of-plane wall anchorage will be highlighted with a summary of the anchorage design and load flow modeling.
