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 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.
本文介绍了量化现有建筑改造总成本的当前实践状况。具体而言，我们结合定量、定性和启发式数据，提供一种分类法，以理解与减轻地震风险相关的直接和间接成本。迄今为止，许多文献都集中在估算改造成本，即建筑物结构构件的改造成本。相比之下，关于总成本中其余成本组成部分的研究和数据非常少。我们建议以结构成本为基础来估算其余成本组成部分以及总成本本身。为了验证我们的发现，我们将所提出的估算值与工程专业人员制定的实际成本估算进行比较。
