Evaluation of Hazard-Resistant Pipelines
Full Project Title:聽Seismic Evaluation of Hazard-Resistant Pipelines: Axial Testing of PVC, PVCO, and iPVC Pipe with Coupling
Year:听2019
Industry Partners:聽East Bay Municipal Utility Department (EBMUD)
CIEST Personnel: Cory Ihnotic, David Kyle Anderson, Jessica Ramos, David聽Balcells, Brice Lucero, John Hindman, and co.
Primary Investigator:聽Prof. Brad Wham
Summary:聽The first in a series of testing programs at CU 海角社区 CIEST聽investigating performance of critical lifeline systems under extreme loading conditions. This study focuses on the聽response of various thermoplastic pipe materials and a coupling connection under externally applied axial and lateral loading.聽 Internally pressurized, 6 in. (150 mm) diameter specimens were tested to failure under various loading scenarios including axial tension, compression, and cyclic loading as well as transverse 4-pt bending. This project initiated聽the development of self-reacting test frame capable of applying dynamic tension and/or compressive loading in excess of聽100,000 lbs (445 kN) to linear structures up to 12 ft (3.66 m) long. CIEST鈥檚 1,000,000 lb (4450 kN) four-post load frame was employed to apply lateral loading. 聽
Appreciation is extended to collaborators David Katzev and Timothy Harris of EBMUD for their intellectual and practical contributions to the project.聽
