Electric resistance strain gage test of 1,000,000 pound test frame

Several years prior to the initiation of the present work, a test frame was developed to provide a static tensile force of 500,000 pounds in the testing of undersea pipe couplings. Within recent years, work was done to increase the test capacity of this frame to 1,000,000 pounds. This thesis presents structural details of the modified frame, a computer analysis of the frame, details and results of a 420,000 pound fracture test and a static test to 980,000 pounds. Electric resistance strain gages were used extensively to obtain strain data during the test work, and a comparison between the computer and experimental results is presented.
