Rational load rating of deck-girder bridges with girder end shear cracks in reverse orientation
Reverse diagonal shear cracking at the supports of many reinforced concrete girders is a phenomenon affecting a number of KDOT’s low-volume bridges built in the early-to-mid 1900’s. This phenomenon is not addressed in the AASHTO Bridge Design Manual (2002) or ACI specifications. This study …

Continuity development between precast beams using prestressed slabs, and its effect on flexure and shear
… The effect that such a slab has on flexural and shear behaviour of the bridge deck has been studied both analytically and experimentally by considering composite beams based on M-8 standard precast beam section. Comparison of the design of bridge decks with a prestressed slab and a reinforced …

High velocity impact fracture
… distinct failure modes including fragmentation, shear plugging, tensile tearing in rigid mass-to-beam impact, confined fracture, petalling, and shear cracking in the Taylor test, are successfully recreated for the first time in the open literature. All of the present predictions are in …

CFRP as Shear and End-Zone Reinforcement for Concrete Bridge Girders
… a single point load near the support to induce shear failure. Beams were fitted with instrumentation to capture shear cracking data. Shear capacity calculations following four methods were compared to test results. Lastly, a parametric study with strut-and-tie modeling was performed on Precast …

C-Grid as Shear Reinforcement in Concrete Bridge Girders
… This thesis concludes that C-Grid is a viable shear design option and presents the initial recommendations for design methods. These methods provide a basis for the design of C-Grid shear reinforcing that could be used as a starting point for future testing of full scale specimens. This testing …

Strengthening of Shear-Critical Reinforced Concrete Beams Using Iron-Based Shape Memory Alloys
… This research study focused on strengthening of shear deficient RC beams and confinement of RC columns due to the brittle failure mechanisms of these members. Investigating such a novel technique relies on experimental testing to better understand the behavior and failure mechanisms. The …

Ridge segmentation, tectonic evolution and rheology of slow-spreading oceanic crust
… deformation, and strain is accommodated by shear cracking. Serpentinites may weaken the lithosphere, enhance strain localization along faults, and control the style of faulting.

Inelastic web crushing performance limits of high-strength-concrete structural walls
… (HSC).The possibility of web crushing failure in shear dominated reinforced concrete element rises when the dimensions of the boundary elements become larger and the webs becomes thinner. Web crushing, or diagonal compression failure, manifests itself as compression failure of concrete struts …

Shear Strength of a PCBT-53 Girder Fabricated with Lightweight, Self-Consolidating Concrete
… The first was to experimentally determine the shear strength of the bridge girder. The initial tests focused on the web-shear strength of the girder, and the second tests focused on the flexure-shear strength. The theoretical predictions for the web shear strength were all conservative when …
