Most large athletic stadiums are constructed using precast concrete tread and riser assemblies bearing on steel beams. Cast-in-place columns typically support the beams. Smaller stadiums can also be constructed in this manner, or can be constructed with concrete bearing on the ground. Most stadium concrete and structural repairs occur at typical locations. Following are examples of these typical locations. The examples give direction on which areas to inspect, as well as provide repair and protection measures that, if taken, will help prevent reoccurrence.
