Can tees be warped to improve drainage on a parking structure?
Yes, we typically warp tees by 3/16″ per foot of width for a 60′ long tee. Tees that are warped by more than this can crack; transverse tensioning is being used in some garages where this criteria needs to be exceeded. 4. What is the maximum length you would recommend for a garage without an expansion joint? Care should be taken in keeping the stiff elements away from the extremities of a garage, but when this is done, it is possible to build a garage up to 325 feet in length without the need for an expansion joint. Attention must also be given to diaphragm loads, and the spacing of shear walls. 5. What floor to floor height is recommended in a parking structure? When the overall height of the structure is not a problem, we recommend floor to floor heights of 10′ – 4″ as a minimum. This will provide a clear height of 7′ – 6″ for each level within the structure, and will help in making the garage feel more open as well as improving the lighting and the visibility of signage.
