Abstract
The state of stress and buckling stability of a bridge structure during construction must be fully understood during the erection process. The live and dead loads that act upon a structure during erection may result in instability of the partially completed structure. For this reason temporary and/or permanent bracing may be required. It is of utmost importance that engineers and contractors understand these principles. Study of the collapse of the Tennessee Highway 69 bridge gives insight into the principles of structural stability during erection. The following gives the reader an understanding of design and analysis techniques that can be used to determine the structural stability of a structure during erection. More importantly, the paper illustrates the effect of lack of stability during erection of a bridge.
