提出了一种考虑结构改造效果的历史建筑经济性能评价方案，为选择合理的改造方法保护历史建筑提供参考。根据先前的研究，地面运动场景（在本文中称为“生命周期地震场景”）被模拟为代表从决策年到建筑物寿命结束年的年度最大地震强度数据。此外，还分析了砌体填充墙作为结构组成部分的历史建筑在“全寿命地震情景”下的结构特性。通过参数分析，考虑生命周期地震情景下结构特征的变化和修复成本，计算历史建筑的经济性能。在此基础上，得到了满足经济性能的需求谱。此需求谱可提供最佳的结构翻新方法，以方便建筑物业主作出有关保存的决定。
An economic performance evaluation scheme of historic buildings that consider the effect of structural renovation is proposed to provide information facilitating to the selection of reasonable renovation methods for preserving historic buildings. Ground motion scenarios, herein referred to as “lifecycle earthquake scenarios” in accordance with the previous research, were simulated to represent the annual maximum earthquake intensity data from the year of decision‐making until the end year of the building's lifetime. Additionally, the structural characteristics of historic buildings with masonry infill walls as part of the structure were analyzed under the “lifecycle earthquake scenarios.” Through a parametric analysis accounting for the change in structural characteristics and the repair costs in the lifecycle earthquake scenarios, the economic performance of historic buildings was calculated. Based on the results, the demand spectrum that satisfied the economic performance was obtained. This demand spectrum can provide the optimal structural renovation method to facilitate the building owner in making decisions regarding preservation.
