摘要：

Quantifying the residual stresses sigma (fr) in tension is one of the most critical issues in the theory of steel-fiber-reinforced concrete (SFRC). The objective of this investigation is to determine the stress-crack opening relation of SFRC. An inverse technique is proposed for the determination of sigma (fr) by employing experimental data from three-point bending tests on notched members. The nonlinear finite-element analysis program ATENA is utilized to verify the stress-crack opening relation obtained. A comparison of simulated load-crack tip opening displacement curves with experimental data attests to the adequacy of the inverse technique.
