Abstract:
In most engineering firms tilt-up wall design is done by one of three methods: hand calculations, spreadsheets, or similar in-house calculations, or using commercially available software. Once established in an office, the underlying assumptions of these methods are often used for some time without being revisited or updated. At times, engineers may believe they’ve improved upon the code provisions with alternate equations from research or simply using a much more involved computational process with complex iterations or finite element modeling. While it might be tempting to deviate from the design provisions within ACI 318 it is important that it is done with a clear understanding of the ramifications, which in reality can often be invalid and unconservative. This presentation is based on the recently released Tech Note: PRC-551.3-21 Pitfalls of Deviating from ACI 318 Slender Wall Provisions.
