Flexural behavior and finite element analysis of waste tires steel fiber reinforced concrete beams with basalt reinforcement

Abstract

Waste Tire Steel Fiber(WTSF) was used in different proportions (0%, 0.5%).1% and 1.5%) were mixed with ordinary concrete to produce WTSF reinforced concrete. Based on basalt fiber reinforced polymer and WTSF concrete, a new structural system, WTSF concrete beam with basalt reinforcement, is proposed. On the basis of the theory test, using the ABAQUS finite element software to simulate basalt rebar waste of the bending properties of steel fiber concrete beam, to obtain the stress nephogram, cracking load, ultimate bearing capacity, load deflection curves and crack location map, comparative tests and fitting results show that WTSF volume content 0% less muscle damage, 0.5% for balance, 1% and 1.5% are superreinforced failure. With the increase of WTSF content, both cracking load and ultimate bearing capacity are improved. Meanwhile, theoretical calculation formulas of relevant components are given to guide engineering practice.
