Pre-stressing concrete where high-strength steel tendons (cables or bars) are tensioned after the concrete has been poured and has achieved sufficient strength. This process introduces an internal compressive force into the concrete element, which actively counteracts the tensile forces that will be created by the structure’s own weight (dead load) and traffic/use (live load). The […]

“Choosing the right expansion joint involves balancing movement demands, traffic intensity, environmental exposure, and maintenance capabilities. This matrix helps engineers match joint types to project needs, ensuring durability and performance.”

“Elastomeric rubber is the unsung hero of many expansion joint systems. Its flexibility and sealing properties make it ideal for absorbing movement and preventing water ingress. Whether in compression seals, strip seals, or modular joints, elastomers ensure performance and longevity.” A flexible, durable material (e.g., neoprene, EPDM)

“Bridges are dynamic structures constantly exposed to environmental and mechanical forces. Temperature changes, seismic events, traffic loads, and even wind can cause movement. Understanding these forces helps engineers design joints that absorb stress and protect the structure.”

Key Functions of an Expansion Joint: Bridges are not rigid, stationary structures; they are constantly moving in response to several environmental and load factors. The expansion joint manages these movements: Modular Expansion Joints “Modular expansion joints are engineered for bridges that experience significant movement. Their multi-beam design allows them to absorb forces in all directions—longitudinal,

Bearing pads, a type of bridge bearing, are essential components used in bridge construction to safely connect the superstructure (the bridge deck and beams) to the substructure (the piers and abutments). Their primary purpose is to transmit loads while allowing controlled movement between the two parts of the bridge. Key Functions of Bearing Pads Bearing
