Abstract: Owing to the excellent crack resistance of steel fiber reinforced self-stressing concrete (SFRSSC for short), the flexural performance and crack resistance of a two-span continuous composite beam with SFRSSC laminated layers were investigated. The experimental results show that the cracking load and the ultimate mid-span deflection of the test beams are increased greatly. Meanwhile, the cracks develop slowly around the support and the flexural behavior of continuous composite beam is improved obviously. Furthermore, a procedure to determine the crack load of SFRSSC continuous composite beams was established and a FEM simulation was given. The theoretical results are in good agreement with the test results and the numerical results, which indicates that the method can evaluate the crack resistance of continuous composite beams.

Key words: self-stressing concrete, composite beam, bend, cracking load, deflection
