Tilt-up construction is one of the most ubiquitous forms of commercial construction in many parts of the country. Thanks to its efficient wall and roof systems, more than 700 million ft2 (65 million m2) of tilt-up buildings were constructed in the U.S. in 2006.1
Tilt-up's current popularity is even more remarkable considering that it wasn't until the 1980s that building codes began to recognize the unique design of slender tilt-up wall panels. In fact, it wasn't until ACI 318-992 was published that the design of slender wall panels was codified on a national level. Of course, the building code is a living document that evolves to reflect current understanding. This article provides background information on proposed revisions to ACI 318 slender wall provisions that govern the design of tilt-up wall panels.
