Measuring Displacement before and after Repair on Korean Wooden Built Heritage: Records for Authenticity and Sustainability

Abstract

Korean wooden built heritage is periodically repaired due to inherent material characteristics that necessitate inevitable changes. This study delves into a detailed point-by-point displacement analysis of Korean wooden built heritage, both pre- and post-repair. Specifically, this study examines the displacement of key points before repair, immediately after repair, and after a four-year interval, focusing on the Sungryeoljeon Shrine in Namhansanseong, a designated World Heritage Site. While substantial changes were observed before and immediately after repairs were made, this study revealed minimal alterations during the subsequent four-year period. However, significant displacement is anticipated when future repairs become necessary. This study posits that accumulating records, which meticulously document these displacements in Korean wooden built heritage, is critical to ensuring the authenticity and sustainability of these historic architectural treasures.
