RISEvaluation of In-Service Performance of Tom’s Creek Bridge Fiber-Reinforced Polymer Superstructure
Publisher: American Society of Civil Engineers
Abstract: The Tom’s Creek Bridge is a small-scale demonstration project involving the use of fiber-reinforced polymer (FRP) composite girders as the main load-carrying members. The project is intended to serve two purposes. First, ...
Investigation of Bridge Floor-Truss Behavior in Tied-Arch Span
Publisher: American Society of Civil Engineers
Abstract: Floor trusses are often used as primary load-carrying members in a bridge superstructure. Load is typically transferred to the floor truss from the concrete deck through the stringers. The floor truss can be supported by ...
Shear Strength of a Lightweight Self-Consolidating Concrete Bridge Girder
Publisher: American Society of Civil Engineers
Abstract: Lightweight self-consolidating concrete (LWSCC) is advantageous in the bridge industry because members made with this material have a significantly lower self-weight, and in its fresh state, LWSCC has a low viscosity which ...
Live Load Testing of NEXT-D Bridges to Determine Distribution Factors for Moment
Publisher: ASCE
Abstract: Live load tests were conducted on an in-service bridge containing decked Northeast Extreme Tee (NEXT-D) girders. The purpose of the tests was to evaluate transverse load distribution and to determine which (if any) of the ...
Live-Load Testing of Flat Precast Slab Bridge to Determine Joint Efficiency and Distribution Factors for Moment
Publisher: ASCE
Abstract: A live-load test was conducted on an in-service bridge containing flat precast concrete slabs. The purpose of the test was to evaluate transverse load distribution and efficiency of the longitudinal slab-to-slab joints. ...
Evaluation of Two Strengthening Methods for Rural Short-Span Precast Concrete Bridges in South Carolina
Publisher: American Society of Civil Engineers
Abstract: South Carolina has thousands of decades-old precast concrete slab bridges that were designed carry loads smaller than those designated in current standards. This paper presents an experimental program that investigated two ...
Inspecting the Lightweight Precast Concrete Panels in the Woodrow Wilson Bridge Deck of 1982
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of a detailed inspection of the deck panels of the Woodrow Wilson Bridge installed in 1982. The original cast-in-place concrete deck, constructed in 1962, was replaced with full-depth ...
Demonstration of Use of High-Performance Lightweight Concrete in Bridge Superstructure in Virginia
Publisher: American Society of Civil Engineers
Abstract: The general objective of this research was the construction and evaluation of a bridge using high-performance lightweight concrete (HPLWC). The resulting bridge over the Chickahominy River near Richmond, Va., consists of ...
Pedestrian Bridge Collapse and Failure Analysis in Giles County, Virginia
Publisher: American Society of Civil Engineers
Abstract: A pedestrian suspension bridge over Walker Creek near Route 749 in Giles County, Virginia, partially collapsed in October of 2008, causing 10 people to fall into the creek below. The failure occurred when one of the anchors ...
Laboratory and Field Performance of Cellular Fiber-Reinforced Polymer Composite Bridge Deck Systems
Publisher: American Society of Civil Engineers
Abstract: This paper addresses the laboratory and field performance of multicellular fiber-reinforced polymer (FRP) composite bridge deck systems produced from adhesively bonded pultrusions. Two methods of deck contact loading were ...
