Evaluation index for residual value of historic wooden-brick buildings

This article proposes a quantitative method for assessing the residual value of historic wooden-brick buildings after structural damage. Conventional assessments rely heavily on expert evaluations, which are both time consuming and subjective. To address this limitation, this study introduces a method using observed structural conditions (including inclination, excessive deflection, and cracking) to estimate the residual value based on structural damage levels. The type of heritage value (historic and artistic) is defined, and the loss rate of each type is determined by evaluating the structural damage. The method was validated primarily using 23 cases of historic wooden-brick buildings located in the ancient village of Suzhou, with the findings suggesting the potential practicality of the proposed evaluation framework for real applications. The study highlights that effective structural health monitoring can facilitate efficient and accurate heritage management, potentially aiding long-term conservation management.
