“…For the shear characteristics after cracking, the Habasaki model (Habasaki et al 2000) was used. The mechanical properties of cylindrical specimens of both ASR concrete (at 12 months exposure) and ASR free concrete are shown in Table 5.…”

Lateral loading tests using reduced reinforced concrete (RC) walls affected by alkali-silica reactions (ASR) and their simulation analyses were performed in order to evaluate the influence of ASR on the structural performance of shear walls that act as seismic resistant members in nuclear power facilities. The state of RC walls was also measured by several techniques to assess applicable monitoring methods during ASR expansion. The transition of the elastic wave velocity of the walls by the ultrasonic method has a good co-relationship with the transition of the static elastic modulus of the cylindrical specimens, indicating that non-destructive testing could capture the degradation trend of concrete due to ASR expansion. The initial stiffness of the ASR specimens became slightly smaller than that without ASR, but the maximum strength remained at the same level with or without ASR. Based on the results of experiments and analyses, a practically appropriate structural performance evaluation method and a monitoring method of ASR affected RC members were proposed.

“…Ct is a coefficient showing the tension stiffening properties. The Collins model (Vecchio and Collins 1982) was used for reduction of compressive strength caused by cracks, and the Habasaki model (Habasaki et al 2000) for shear transfer characteristics of the cracked surfaces. For the stress-strain relation of reinforcement, the Zulfiqar-Filippou model (Zulfiqar 1990) was used.…”

In this study, we made examinations by means of experimental and analytical methods for the purpose of grasping the shear characteristics of RC walls with corroded reinforcement and verified the validity of analytical models and constitutive laws by making comparisons between the analysis results and the test results. First of all, we conducted two kinds of element tests on the bond strength of reinforcement greatly affected by corroded reinforcement and tension stiffening of concrete around the reinforcement. Regardless of the diameter of the reinforcement, we found that the bond strength could be assessed using past equations and, for tension stiffening, proposed an equation in consideration of the effect of corrosion weight loss by obtaining data of constitutive laws for FEM analyses. Then, we conducted in-plane shearing tests on the RC walls with corroded reinforcement and found that the effect of the corrosion weight loss of reinforcement on the shear strength of the walls was low. Finally, we found that the analyses almost follow the test results through FEM analyses of the RC shear walls with corroded reinforcement using the constitutive laws obtained through element tests and past constitutive laws.
