Since our country could get good quality of stones easier than China and Japan, beautiful and various stone constructions, such as stone pagoda, rock cliff Budda and etc, had been made from the age of the three States. These stone constructions with culture and historic values are preserved and managed by the country specifying as national treasures, treasures and etc. However, even though stone is a strong durable material, being exposed by rain or wind for years makes it weather or show structural damage by conduct of the ground. According to these situation, Cultural Properties Information Plaza investigated efflorescence, creature, structural deterioration on National treasure properties from 2001 to 2005. This study aims to analyze the relations between each deterioration factors based on the result of this research and grasp the structural deterioration of the stone cultural properties.

A DSB (Disc Spring Brace) was developed to avoid brittle failure at beam-column connections and to induce plastic hinges at the beam sections. Its structural performance was verified experimentally. Test results show that the DSBs prevent buckling response and residual deformations and their structural capacity can be adjusted according to the distribution of disc springs.
