Abstract:Expert experience indicates that there are certain errors and generally low credibility in the assessments of the seismic safety of building structures in relic parks. To address this issue, we propose a new seismic safety assessment method for building structures in relic parks. We constructed a material constitutive model to determine the structural damage that would occur in a relic park, and obtained a local damage index of the structure using the local damage index evaluation model. Then, we calculated an overall structural damage index for buildings in relic parks based on the local damage index. Taking as an example the architectural structure of the ancient Roman ruins park, we performed a seismic safety analysis. The results showed that when the amplitude of the seismic wave reached 800 gal, the seismic safety of this park was poorest, and the degree of damage was high. The analysis results of the proposed method were highly accurate and reliable.
