FRP STRUCTURE DESIGN METHOD BASED ON EQUALITY OF STIFFNESS: CASE STUDY AND PRACTICE
Keywords:fiber reinforced polymer, civil engineering, structure design, durability, construction material
AbstractNowadays, Fiber reinforced polymer materials are getting widely used in civil engineering. They have some advanced engineering characters like high stiffness-to-weight ratio, high strength-to-weight ratio, anti-electromagnetic interference, electrical isolation and its long time durability. Metal and concrete, those main kinds of construction material, are prone to be failed before the structure service life because of the environmental attacks. Those harsh attacks are oxidization, acidification, high temperature and alkali corrosion. After the maintenance methods like isolating the attacks or protecting plastic skins, the interfaces between the protections are easily to be cracked and it caused the same worry on durability problems. Fiber reinforced polymer stands for a new era of civil engineering and surely the traditional material can be substituted by fiber reinforced polymer. This paper wants to unfold a case study on how fiber reinforced polymer worked in civil structures.
