Abstract
At this, in this study, some tests were conducted to come up with a method to minimize intervention, to reduce the secondary damage to original materials, and to produce remarkable reinforcing effects. The followings show objective standards. The proportion of original material to steel reinforcement bar (the ratio of steel reinforcement bar) needs to be calculated in light of weathering intensity. Second, in the case of partial damage, prosthetic treatment is applied to add new stone materials to original materials. In that case, the ratio of steel reinforcement bar should be calculated based on material that is highly resistant to weathering. With the results of this study, it is possible to suggest conditions that can structurally stabilize stone cultural heritage, according to the weathering area. As a result, the ratio of steel reinforcement bars can be 0.13 to 0.23 in the case of $800kgf/cm^2$ or less, 0.24 to 0.28 in $800kgf/cm^2$ or higher, and 0.29 to 0.5 in $1200kgf/cm^2$ or higher. In particular, there is the need to take the coefficient of rupture of stone material and the properties of the steel reinforcement bar into account in cases of calculating the ratio of steel reinforcement bars according to weathering intensity.
