Tecnologies
Composite Materials – FRP In Civil Engineering
• Do not add additional loads to the structure
• Possibility to design "ad hoc" based on the directions of stress
• Speed of operation
• Reversibility
• No change to the original geometry
• Increased flexibility of the structure
Advantages of composite materials
1. Realization of composite structures (structural profiles);
2. Reinforcement of existing structure of various types and materials.
3. Reinforcement of traditional materials such as concrete, masonry and wood;
Applications
Kolding Bridge - DenmarkLaurel Lick Bridge - West Virginia
Realization of Composite Structure
• Reinforcement of concrete and masonry
• Structural reinforcement in the case of armor worn, change of destination or other;
• Reinforced cutting and bending of reinforced concrete beams;
• Reinforcement in bending and axial force of columns in reinforced concrete and masonry for increased loads or inadequate armor;
• Reinforcement of steel structure;
• Reinforcement of wood structure;
• Reinforcement of bridges;
