Where Tilt-Up Is Used
Where tilt-up is used as an industrial product, this is less of a problem. Industrial floor slabs are usually designed for heavy loads. Retail and commercial construction, however, place less loading demands on the floor slab and more emphasis on the external appearance. Accordingly, commercial and retail construction typically have floor slabs that are not designed for industrial or construction type loading.
For retail and commercial tilt-up, the floor slab can rarely “theoretically” support the load of the service crane.
Although a heavily overloaded slab can usually tolerate one or two passes of the crane, structural failure often
occurs after only a few passes.
