Deterioration of the end regions of prestressed concrete bridge girders is commonly observed in the field when girders are exposed to chloride-laden water that has leaked through failed expansion joints. Because the deterioration is often localized t

Leaking longitudinal joints are commonly observed in adjacent box-beam bridges and are often associated with an assumed loss of load distribution at the leaking joint. To address the lack of test data and general uncertainty in analyzing deteriorated

To support the adoption of high-strength reinforcement (fy > 60 ksi) into widespread use, it is fundamental that appropriate development and splice lengths be calculated. The objective of this research is to evaluate the development of high-strength

A three-dimensional elastoplastic soil constitutive model capable of capturing the response of granular soils under low-frequency cyclic loading is introduced and verified. The model is piecewise linear with a hyperbolic stress-strain relationship. T
