Significant cracking was discovered in a multistory parking garage shortly after construction. Was it safe to open? Based on visual inspection, a bridge was down-rated, with potential adverse effects on traffic and the local economy. Was this action necessary? A one-of-a-kind amusement ride was subjected to stresses in operation that were not predicted in the initial structural design. What impact would this have on the structure's failure potential? Failure of a truck-mounted hydraulic trash loader resulted in a fatality. What was the cause ahd how could it be corrected? These questions were addressed in four recent projects through the use of computerized data-acquisition systems. The use of portable computers, advanced modular high speed data acquisition devices, and software data reduction allow the collection and analysis of thousands of data points. Examples of these applications are used to show the benefit of this method over previous manual data collection and reduction
