Applications of finite element method in studying mechanical behavior of concrete materials on different scales
… for estimating the opening at concrete expansion joints. After further considering the actual boundary condition, the modeling effort demonstrates acceptable accuracy of the simulation result. The good agreement between the FEM simulation and the field measurement confirms a realistic …

Monitoring and Fatigue Analysis of Suspension Bridge Rocker Arms
… 2015 causing the deck to descend 150 mm at the expansion joint. The entire rocker arm assembly was replaced, and by 2021 concerns about the other seven rocker arms led to the installation of a monitoring system consisting of 32 vibrating wire strain gauges. This thesis describes the collection …

The tensile performance of closed cell foam expansion joints: a study on the deleterious effects of compression set
… material for a specific type of bridge deck expansion joint, usually in applications where the total movement to be accommodated is four inches or less. Adhered into the gap of an expansion joint, this material is responsible for maintaining a water tight smooth transition between deck slabs, …

Measuring and predicting sealant adhesion
… to predict the long term performance of sealant joints independent of the joint geometry. The material properties of a silicone sealant were characterized as a function of temperature, relative humidity and test rate. The fracture energy of the silicone sealant bonded to glass, aluminum or …

Development, Testing, and Evaluation of Bridge Bearing Movement Sensor System
Bridge bearings and expansion joints are critical features of bridges as they prevent the buildup of thermal stresses caused by changing temperatures. Current assessment techniques include visual inspections which are subject to inaccuracies based on the inspectors' judgement. Therefore, innovation …

Tensile Testing of Cold-Applied Joint Sealants
… in concrete pavement systems are the concrete joints. They are man-made cracks that allow for temperature-related expansion and contraction of concrete slabs. Sealants are commonly used in pavement joints to keep debris, deicing chemicals, and moisture out of the joint. When a joint sealant …

On the Performance of Super-Long Integral Abutment Bridges: Parametric Analyses and Design Optimization
… as a single structural unit; the elimination of expansion joint and bearings on the abutments, greatly reduce the construction and maintenance costs. To maximize the benefits from integral abutment bridges, the direct way is to achieve the super-long integral abutment bridge. However, as the …

Seismic behavior and design of integral abutment bridges in southern Illinois
… in modern bridge design due to their lack of expansion joints between the superstructure and abutment, which can lead to decreased damage at the abutment seat when compared to stub abutment bridges because water, soil, and deicing chemicals are unable to penetrate through a compromised …
