Development of a Composite Concrete Bridge System for Short-to-Medium-Span Bridges
… bridge construction alternative for short-to-medium-span bridges. The system consists of adjacent precast inverted T-beams finished with a cast-in-place concrete topping. The system offers enhanced performance against reflective cracking, and reduces the likelihood of cracking due to time …

Development of a Minimal Information Data - modelling approach for the monitoring of short and medium span bridges
… monitor the structural behaviour of short and medium span bridges. A significant number of bridges in many countries are approaching or have exceeded their design life. For this reason, structural health monitoring (SHM) has been widely studied in the last two decades. However, the industrial …

Fiber-Reinforced Polymer Bridge Girders for Extremely Aggressive Environments
… maintenance, and replacement of the nation’s bridges. While the average lifespan of steel and reinforced concrete bridges is 50 years, certain bridges subjected to extremely aggressive marine environments may not reach this desired target. This research paper investigates using …

Shear Reliability Analysis of Reinforced Concrete Bridges Designed to TMH7
… the code for the design of reinforced concrete bridges in South Africa. Its normal traffic load model (NA loading), based on the outdated BS5400 design code and 1972 traffic loads, has not been updated to account for the changes in traffic demands. Thereby, the validity of TMH7 in simulating the …

Rectification of 2-D to 3-D Finite Element Analysis in Buried Concrete Arches Under Discrete Loading
<p>Construction of tunnels and small- to medium-span bridges is a $12 billion per year industry in the United States, with a significant portion going into buried arch structures. Notwithstanding such expenditure, modern arch design and construction, in many cases, is highly conservative. This is …

New Approach to Connections Between Members of Adjacent Box Beam Bridges
The adjacent box beam bridges (ABBB) are considered as an ideal solution for short to medium span bridges and for routes with low to medium traffic volumes. The ABBB system has been utilized and is popular in several states in the United States. However, this bridge system has long term durability …

Vibration based performance assessment of concrete-concrete composite bridges
… have been used for the construction of short to medium span bridges for the past four decades in South Africa and worldwide. The pre-cast beams and cast in-situ slab are commonly connected using shear connectors. Failure of these connectors would compromise the composite action of the structure, …
