Literature and telephone surveys were conducted to determine the current status of fracture control as practiced by U.S. designers, builders, and operators. From this, recommendations are made for strengthening industry practices promising areas for research are identified and prioritized, as are areas where cost-effective improvements could be made within existing technology. A fracture control checklist is also provided as an example of an unstructured, yet responsive, fracture control plan. It appears that there are two basic types of fracture problems. One type occurs because of poor workmanship or direct human error. Examples of this are significant crack initiations due to poor welding technique, construction overloads, and falling objects. Fracture control is achieved in these cases by preventing the errors from occurring.
