Field Testing and Structural Analysis of Burr Arch Covered Bridges in Pennsylvania
Field Testing and Structural Analysis of Burr Arch Covered Bridges in Pennsylvania Douglas Rammer1, James Wacker2, Travis Hosteng3, Justin Dahlberg4 and Yaohua Deng5 ABSTRACT: The Federal Highway Administration sponsored a comprehensive research program on Historic Covered Timber Bridges in the USA. This national program's main purpose is to develop improved methods to preserve, rehabilitate, and restore timber bridge trusses that were developed during the early 1800s and, in many cases, are still in service today. One of the many ongoing research studies is aimed at establishing a procedure for safely and reliably load- rating historic covered bridges though physical testing and improved structural modelling. This paper focuses on recent field work and analysis of four Burr Arch through-truss-type covered bridges located in Lancaster County, Pennsylvania. An overview of field evaluation methods, loading testing, and structural modelling procedures are included along with a comparison of field measurements and structural model prediction of bridge behaviour. KEYWORDS: loading rating, structural analysis, covered bridges, historical landmark, burr arch 1 INTRODUCTION 123 established for historic covered bridges.

Shipping in Pacific Northwest Halted Due to Cracked Barge Lock at Bonneville Dam
Shipping in Pacific Northwest Halted Due to Cracked Barge Lock at Bonneville Dam Reports of a broken barge lock at the Bonneville Dam on the Columbia River surfaced on September 9th. The crack was discovered last week and crews began working Monday morning on repairs. The cause of the damage is unknown. To begin the repairs, the crews must first demolish the cracked concrete section. It remains unclear, however, when the repairs will be complete. Navigation locks allow barges to pass through the concrete dams that were built across the Columbia and Snake Rivers to generate hydroelectricity for the West. A boat will enter the lock which is then sealed. The water is then lowered or raised inside the lock to match the level of the river on the other side of the dam. When the levels match, the lock is then opened and the boat exits. The concrete that needs to be repaired acts as the seal for the lock. The damage to the concrete at the Bonneville Dam resulted in significant leaking—enough that water levels were falling when the lock was in operation. Thus, immediate repair was necessary. The Columbia River is a major shipping highway and the shutdown means barges cannot transport millions of tons of wheat, wood, and other goods from the inland Pacific Northwest to other markets. Eight million tons of cargo travel inland on the Columbia and Snake rivers each year. Kristin Meira, the executive director of the Pacific Northwest Waterways Association said that 53% of U.S. wheat exports were transported on the Columbia River in 2017. -

Glossary of Terms 61 The McKenzie River Subbasin Assessment was funded by grants from the Bonneville Power Administration and the U.S. Forest Service. High Priority Action Items for Conservation, Restoration, and Monitoring Our analysis indicates that aquatic and wildlife habitat in the McKenzie River subbasin is relatively good yet habitat quality falls short of historical conditions. High quality habitat currently exists at many locations along the McKenzie River. This assessment concluded, however, that the river’s current condition, combined with existing management and regulations, does not ensure conservation or restoration of high quality habitat in the long term. Significant short-term improvements in aquatic and wildlife habitat are not likely to happen through regulatory action. Current regulations rarely address remedies for past actions. Furthermore, regulations and the necessary enforcement can fall short of attaining conservation goals. Regulations are most effective in ensuring that habitat quality trends improve over the long period. -

Sponsoring Agency Code 15. Supplementary Notes 16. ABSTRACT Recent experience in the Coast Range Province of Oregon demonstrates that weak sedimentary bedrock in stream channels can be vulnerable to scour. The presence of erodible rock adjacent to bridge foundations and abutments necessitates monitoring of the channel to preclude costly repairs, or in an extreme case undermining of the foundations and bridge collapse. -

Covered Bridges Tour 10/4/2009
ORPCA COVERED BRIDGES TOUR 10/4/2009 Tour created by Bob and Kathleen Ellis Abiqua Creek (Gallon House) Covered Bridge Background: The Gallon House Bridge, the last of Marion County's original covered bridges, is located over Abiqua Creek a little more than a mile northwest of Silverton. The name Gallon House was due to the bridge's use as a "pigeon drop" for liquor at the north entrance. Operators at a liquor dispensary nearby sold "white lightening" whiskey by the gallon to Silverton residents. At the time, Silverton was "dry," not allowing liquor to be sold in town, while Mt. Angel was "wet." County: Marion The Gallon House along Abiqua Creek was in Mt. Angel territory. Stream: Abiqua Creek During the 1964 Christmas Flood, the bridge suffered considerable Bridge Length (ft): 84 damage. The County Board of Commissioners, however, decided the Year Built: 1917 bridge should be repaired and maintained as an historical landmark, as it was the only covered bridge in the county at the time. In 1985, the old wooden structure was closed to all traffic when a damaged chord rendered it useless. County road crews repaired the bridge to accept traffic up to a 10-ton limit by reinforcing a lower chord, as well as making repairs to the beams and flooring. Also included in the renovation was a change in the size and shape of the portals. The revamped portals were hinged to allow them to be opened for taller loads when necessary. In 1990, because of poor structural condition, the bridge was rehabilitated to mint condition and the hinged portals were removed.
