CTL and AE Methods of In-Situ Load Testing: Comparison and Development of Evaluation Criteria IN-Situ Evaluation of Post-Tensioned Parking Garage, Kansas City, Missouri

摘要

The objective of the proposed research project is to compare the results of two recently introduced nondestructive load test methods to the existing 24-hour load test method described in Chapter 20 of ACI 318-05. The two new methods of nondestructive evaluation are the Cyclic Load Test (CLT) and Acoustic Emission (AE) methods. Each method offers advantages over the 24-hour load test method and each is particularly well suited to different aspects of structural evaluation. The focus of the research effort is an existing reinforced concrete (RC) building in Kansas City, Missouri. This building provides an ideal real world test bed for comparison between the three different methods of in-situ evaluation (24-hour, CLT, and AE methods).
