Building capacity for disaster risk reduction requires integrating local and scientific knowledge. We focus on local and scientific knowledge of the safety of housing in typhoons' wind, focusing on roof and wall systems. To identify alignments and misalignments between household and engineering understanding of safe housing, we conducted semi-structured interviews with 170 households that received new houses from organizations following Typhoon Yolanda in the Philippines. We qualitatively coded and analyzed these interviews to identify what housing components households expect to fail first, their preferred failure, and how they plan to modify their house to be safer in typhoons. We compared these responses to three results from engineering assessments: the governing failure mode, the failure mode that best meets safety performance objectives, and the quantified impact of design modifications. Household perceptions and engineering assessments were well-aligned when focusing on the damage expected to a single component and how to improve the performance of a single component. However, perceptions and assessments were misaligned at the housing level as households did not consider how housing components worked together as a system to influence performance. Households often did not recognize that modifying one component, such as the roof, would have an adverse impact on the performance of other components, such as the wall. This study is one of the first to systematically compare perceptions and assessments of housing safety and advances understanding of alignment, or misalignment, of local and scientific knowledge of safe building practices. We recommend that future post-disaster training programs incorporate discussions of a house's load path to focus on how components work together, enabling design and modification decisions that support improved housing performance.

建设减少灾害风险的能力需要整合当地知识和科学知识。我们专注于本地和科学知识，以防台风影响房屋，并着重于屋顶和墙壁系统。为了确定住户与工程学对安全住房的理解之间的异同，我们对170户家庭进行了半结构化访谈，这些家庭是在菲律宾台风Yolanda飓风过后从组织那里获得新房屋的。我们对采访进行了定性编码和分析，以找出住户希望首先破坏的房屋部件，他们的首选失误以及他们计划如何改造房屋以使其在台风中更安全。我们将这些回应与工程评估的三项结果进行了比较：治理故障模式，最能满足安全性能目标的故障模式，以及设计修改的量化影响。在关注预期对单个组件造成的损害以及如何提高单个组件的性能时，家庭的看法和工程评估是非常一致的。但是，由于家庭没有考虑住房组成部分如何共同作为影响绩效的系统，因此人们对住房的看法和评估没有统一。家庭通常不认识到修改一个组件（例如屋顶）会对其他组件（例如墙壁）的性能产生不利影响。这项研究是第一个系统地比较对房屋安全的看法和评估，并加深对本地和科学的安全建筑实践知识的一致性或不一致性的理解的研究之一。
