Project Title:ÌýTension Testing of Flexible Expansion Joints Ìý

Industry Partners: EBAA Iron, Inc.Ìý

CIEST Personnel:ÌýHailey Parnell, Lindsay Guerrero, Bruce Lucero

Primary Investigator:ÌýProf. Brad WhamÌý

Year:Ìý2020Ìý

Project Summary:ÌýÌýThe intent of the test program is toÌýinvestigateÌýthe axial performance of a Flex-Tend Flexible Expansion Joint (FEJ) and a Force-Balanced FlexTend Flexible Expansion Joint (FBFEJ), each nominally 6-in. diameter. Externally applied axial tension load test results are compared to data obtained from internal pressure burst tests and demonstrate that, while similar levels of axial force are required to initiate component failure, the failure mechanisms differ and and influenced by the circumferential stress supplied during burst testing. The work was undertaken in the Center for Infrastructure, Energy, and Space Testing (CIEST) which is affiliated with the Civil, Environmental, and Architectural Engineering Department at the Â鶹ÊÓƵ.
