Abstract
The purpose of this study was to estimate the edge distance of metal rod reinforced flexural members in the Stone Pagoda of the Mireuk Temple Site. Flexural tests for forty reinforced granite members were performed to evaluate the flexural strength depending on the area of metal rod and edge distance. In addition, uniaxial compression and tension tests were conducted to obtain the material properties of the granites and the metal rods. The flexural strength and design flexural moment strength for the reinforced granite members were proposed. The predicted flexural strength was agreed well with the test results. The minimum reinforcement ratio was also proposed by using the brittleness number (<TEX>$N_p$</TEX>). In order to inhibit brittle failure, the brittleness number for reinforced granite stones should be 0.1 ~ 0.3. The edge distance of the reinforced flexural members with metal rods was proposed by depending on the area of the metal rods based on the test results.
