Abstract

The special feature of restoration and strengthening of timber beam elements in ancient Chinese buildings is that it is not only necessary to prolong their life, but also to protect their value to the greatest extent possible. The traditional restoration and strengthening techniques commonly used are difficult to quantify the results, and there is a risk of over-intervention in the determination of damage and restoration work, which can easily lead to changes in the original appearance of ancient buildings and loss of value information. By exploring concealed restoration and strengthening techniques at the component and node levels, we aim to further enrich preventive conservation methods and better protect and pass on valuable cultural heritage.
