遗址建筑结构在不同地震作用下安全性能分析
Safety Performance of Building Structures in Relic Parks under Different Earthquakes

以往通过专家经验判断遗址公园建筑结构地震安全性时存在一定误差，可信性低，因此提出新的遗址公园建筑结构的地震安全性鉴定方法。构建材料本构模型，判断遗址公园建筑结构损伤情况；使用局部损伤指数评价模型，计算遗址公园建筑结构局部损伤指数；通过局部损伤指数获取遗址公园建筑整体结构损伤指数，以此为依据判断遗址公园建筑结构地震安全性。以古罗马遗址公园建筑结构为例，进行地震安全性分析。结果显示，当地震波幅值达到800 gal时，该遗址公园建筑结构地震安全性最差，损坏程度为高度损坏，且此方法的分析结果精度极高，可信性强。
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
