This article presents the current state-of-practice with respect to quantifying the total cost to retrofit an existing building. In particular, we combine quantitative, qualitative, and heuristic data to provide a taxonomy for understanding the direct and indirect costs associated with seismic risk mitigation. Much of the literature to date has focused on estimating structural retrofit costs, the costs of retrofitting the structural elements of a building. In contrast, there is very little research or data on the remaining cost components of the total cost. We propose using structural cost as the foundation for approximating the remaining cost components and the total cost itself. To validate our findings, we compare the proposed approximations with actual cost estimates developed by engineering professionals.

本文介绍了关于量化改造现有建筑物的总成本的当前实践状态。特别是，我们结合定量、定性和启发式数据来提供分类法，以了解与地震风险缓解相关的直接和间接成本。迄今为止，许多文献都侧重于估算结构改造成本，即改造建筑物结构元素的成本。相比之下，关于总成本中剩余成本组成部分的研究或数据非常少。我们建议使用结构成本作为估算剩余成本组成部分和总成本本身的基础。为了验证我们的发现，我们将建议的近似值与工程专业人员开发的实际成本估算进行了比较。
