The use of FRP (Fiber Reinforced Polymer) members has revolutionized the construction industry, especially in the field of bridge construction. These members are made of composite materials that are stronger and more durable than traditional materials like steel and concrete. The introduction of FRP members in bridge construction has resulted in several significant advancements.
Firstly, FRP members are used in the construction of new bridges, which allows for the creation of longer and wider bridges that can carry heavier loads. This is because FRP members have a higher load-carrying capacity than traditional materials. Additionally, they can be manufactured in various shapes and sizes to fit the specific needs of each bridge project.
Secondly, FRP members are also used in the repair and strengthening of existing bridge structures. This is particularly important for older bridges that may have deteriorated over time due to exposure to harsh weather conditions and heavy traffic. By using FRP members, these structures can be reinforced and repaired, resulting in increased safety and longevity.
Finally, the use of FRP members in bridge construction can lead to reduced maintenance costs. These materials are highly resistant to corrosion and do not require regular maintenance like traditional materials. As a result, bridges constructed using FRP members have a longer service life and require less frequent repairs.
In conclusion, the introduction of FRP members in bridge construction has brought about significant advancements in the industry. These materials offer increased load-carrying capacity, improved safety, reduced maintenance costs, and longer service life. As such, they will continue to play a crucial role in the construction and maintenance of bridges for years to come.
Properties of Non-metallic FRP Rod Strength Member
A. High strength
FRP is stronger than structural steel on a pound-for pound basis.
B. Light weight
FRP is 20-25% the weight of steel and 70% the weight of aluminum. FRP are easily transported, handled and lifted into place.
C. Anti-corrosion
FRP will not rot and are impervious to a broad range of corrosive elements. This feature makes FRP a natural selection for indoor or outdoor structures in corrosive environments.
D. Electro-magnetic transparency
FRP are transparent to radio waves, microwaves and other electromagnetic.
E. Non-conductive
FRP has low thermal/ electrical conductivity.
F. Dimensional stability
The coefficient of thermal expansion of FRP is slightly less than steel and significantly less than aluminum.
