Abstract: This article provides recommendations on how to evaluate existing passive anchorage systems for Tainter gates. A review of various types of passive anchorage systems is provided, along with a detailed example problem. The ...

Abstract: Supercavitating baffle blocks, with their unique geometry, have been shown to be highly effective in reducing cavitation damage to stilling basins’ floors and to the baffle blocks themselves. However, this unique geometry, ...

Abstract: This paper presents a methodology to compare various Tainter gate strut-arm retrofit techniques based on the longevity corrosion maintenance (LCM) factor. The rating system is designed to encourage agencies to select ...

Abstract: This paper reviews the design of accessible anchor galleries that allow the inspection, testing, and replacement of post-tensioned trunnion girder anchorage systems. Various means of egress were reviewed along with features ...

Abstract: This article compares the current estimated debris line-load value of 6.78 kN/m (5 kips/ft) on Tainter gates within engineering manuals and technical letters to recent research findings on impact loads. The intent of this ...

Abstract: This paper reviews the suitability and use of post-tensioned grouted anchors to replace and/or retrofit existing Tainter gate anchorage systems. A thorough historical and theoretical review on both unbonded and bonded ...

Abstract: An experimental test program was performed on grouted post-tensioned anchor rods to determine if anchors with high rod-to-duct area ratios could reanchor themselves upon fracture. Liftoff testing of the grouted anchors was ...

Abstract: This study proposes a conceptual methodology to determine the axial load within a grouted post-tension anchor system via finite element analysis and calibration. The concept was built on the premise that a plate under axial ...
