Title: Large-Scale Testing of Fault Rupture Effects for SFPUC - BDPL3 & 4 Fault Crossing Phase 2 (NEES-2009-0728)

Year Of Curation: 2012

Description: This project includes tests performed for the San Francisco Public Utilities Commission (SFPUC) for the seismic upgrade of Bay Division Pipelines (BDPLs) at specific fault crossings. The tests were performed with the Large-Scale Lifelines Testing Facility at Cornell University, which is part of the George E. Brown, Jr, Network for Earthquake Engineering Research (NEES) supported by the National Science Foundation (NSF). The seismic upgrade of BDPLs 3 and 4 involves the replacement of the existing BDPL 3 at its fault crossing. The design entails enclosing the new BDPL, in a segmental, reinforced concrete vault with special joints that can accommodate lateral offset and compressive deformation during fault rupture, thereby allowing for rotation and compression of the pipeline inside the vault at ball and slip joints, respectively. The length of the protective vault is approximately 300 ft, and the width, height, and lengths of the reinforced concrete segments are approximately 20 ft.
