United States building codes have been very successful in protecting life safety during earthquakes, but they do not aim to protect against damage and high repair costs. Despite societal concerns over economic disruption after a future earthquake, a building's susceptibility to damage is almost never analyzed during the structural design process. This leaves us with a building stock that is vulnerable to damage, monetary loss, and possible closure after an earthquake. This I-Corps team's research activities and long-term vision focus on enabling engineers to consider damage/loss reduction in the building design process. The team's plan is to create a commercial software tool that enables engineers to predict seismic damage and loss as part of the design process. This design approach will be new to many engineers, so the tool will be created to also provide Probable Maximum Loss (PML) analyses results (which engineers are accustomed to doing for the mortgage industry). If successful, this new design approach and the enabling software tool could revolutionize the way that buildings are designed in seismic areas. Specifically, this software tool (and the theory implemented in the tool) will give engineers a clearer understanding of the extent to which buildings will be damaged in earthquakes and provide an estimate of the cost to repair the buildings; this will enable engineers to design buildings in such a way as to reduce the seismic damage and repair costs, instead of using the current approach of only designing buildings to protect the life safety of building occupants.

美国建筑法规在保护地震期间保护生命安全方面非常成功，但它们并不旨在保护损害和高维修费用。尽管社会对未来地震后经济破坏的关注，但在结构设计过程中，建筑物对破坏的敏感性几乎永远不会分析。这给我们留下了一个容易遭受损害，货币损失以及地震后可能关闭的建筑库存。 这个I-Corps团队的研究活动和长期愿景着重于使工程师能够考虑减少建筑物设计过程的损害/损失。该团队的计划是创建一种商业软件工具，使工程师能够预测地震损伤和损失，这是设计过程的一部分。这种设计方法对许多工程师来说是新的，因此将创建该工具以提供可能的最大损失（PML）分析结果（工程师习惯于为抵押行业做到这一点）。如果成功，这种新的设计方法和启用软件工具可能会彻底改变建筑物在地震区域设计的方式。具体而言，该软件工具（以及工具中实施的理论）将使工程师更清楚地了解建筑物在地震中损坏的程度，并估算修复建筑物的成本；这将使工程师能够以降低地震损坏和维修成本的方式设计建筑物，而不是仅使用设计建筑物的当前方法来保护建筑物居民的生活安全。
