This paper presents the results of twelve reinforced concrete shell elements subjected to shear and biaxial stresses. Elements were constructed by one-third scale of real NPP wall elements and were monotonically loaded until failure. The results were compared with predictions from the Modified Compression Field Theory (MCFT). The concrete compressive strength, steel yield strength and reinforcement ratio of APR1400 that is current model of NPP in Korea were used for reference elements. And the high strength concrete, high yield strength steel and decreasing reinforcement ratio were used for other elements. The ultimate load was accurately predicted with a mean test to predicted ratio of 0.95 and a coefficient of variation of 6.6 %. The shear strains at peak stress were also accurately predicted with a mean test to predicted ratio of 1.01 and a coefficient of variation of 13.4 %. These results show the applicability of MCFT to shear design of NPP wall. |
