Filter by Keyword68 report(s) found with tests in the keywords field The overall project is to demonstrate the effectiveness of shear spiking (technique already developed through a previous project). Many timber railroad bridges are deficient but it is too costly to replace them; hence, inexpensive repair techniques are needed. The proposed project will provide the necessary... Field samples were obtained from cores taken from multiple roads around the Salt Lake Valley in Utah and prepared for BBR testing. The response of field cores showed that even though the same binder grade used in the region was the same, the resulting mixtures have significant differences in creep moduli... Depending on the location, highway bridges can often support considerable amounts of traffic. Due to the limitations on current earthquake forecasting techniques, a normal amount of traffic will also typically remain on a bridge when an earthquake occurs. In addition to traffic, scour effects are also... Over the years, Fiber Reinforced Polymer (FRP) composites have gained popularity in transportation infrastructure as a material able to restore and increase the capacity of existing concrete elements. Properties such as a high strength to weight ratio, non-corrosive nature, durability, and high malleability... This report describes research performed in coordination with work at the University of Stuttgart, attempting to establish the S-N curve for fatigue loading of notched wood-concrete connections based on low/high-cycle, repeated loading tests. Experimental results are obtained on fourteen 1524 mm span... Alternatives to existing transportation truck escape ramps and crash barriers are examined using arrays of wood, bamboo, and fiberglass structural elements that act as energy absorbers as they deform. The behaviors of each material type are analyzed to determine if they have the necessary potential for... This report details the outcomes of shear spiking two open-deck, timber trestle railroad bridges and examining the effectiveness under applied loading. The bridges were made available to the researchers by the Union Pacific Railroad and were located in their Southern Region. The first site was located... This research was undertaken to: 1) design and construct a wall and basic subassembly of an emergency storm shelter comprised entirely of wood that could resist a "missile" impact at 100 mph or multiple impacts at 80 mph; 2) study the difference in impact response for various specimen configurations... A structural concept as an alternative to conventional bridge guardrail system for application in timber bridges was conceived in prior related research on an innovative timber bridge system. This paper presents the results of the subsequent study, which was conducted after making the improvements. The... This study presents the results of the most recent phase of laboratory research. The effects of support movements observed in the field test were examined by physical laboratory testing and computer-based structural modeling using AxisVM software [Inter-CAD. Kft, 2004]. The goal of this research was... |
