Non-uniform model of relationship between surface strain and rust expansion force of reinforced concrete

Abstract When operating within the environments rich with sodium chloride, steel bars of reinforced concrete structures are often subject to corrosion caused by surrounding erosive materials, and associated rust expansion force due takes a critical role in determining durability relevant structures. By investigating course reinforcement theory elasticity, numerical model is established for moment surface rupture based on non-uniform sin function. Cuboid specimen squared cross sections tested analyze when cracks corrosive forces. The utility validated simulation Abaqus through comparison between outcomes. impacts bar diameter cover thickness magnitude discussed.
