TL;DR: In this article, the Rankine vortex model was applied to model the pressure deficit resulting from a tornado, and then combined with pressures resulting from wind velocity to develop fragility surfaces for buildings representative of the typical residential building stock in a community.
Abstract: Based on the observation of damage from past tornadoes, tornado intensity is frequently the highest at the center and gradually decreases outward, which is consistent with a Rankine vortex model. In this study, the Rankine vortex model was applied to model the pressure deficit resulting from a tornado, and then combined with pressures resulting from wind velocity to develop fragility surfaces for buildings representative of the typical residential building stock in a community. In the absence of data, an additional coefficient is used herein to consider different amount of pressure deficit participating in wind loads on buildings to enable community resilience studies. However, it is duly noted that at the individual building level the internal pressure coefficient used in ASCE-7 should be adjusted based on data to be consistent with current wind engineering methods in the United States. Moreover, a scenario tornado path was modeled based on historical statistics of U.S. tornadoes over almost four...

TL;DR: The NEES-Soft project was a five-university multi-industry effort that culminated in a series of full-scale soft-story wood-frame building tests to validate retrofit philosophies proposed by (1) the Federal Emergency Management Agency (FEMA) P-807 guidelines and (2) a performance-based seismic retrofit (PBSR) approach developed within the project as discussed by the authors.
Abstract: Soft-story wood-frame buildings have been recognized as a disaster preparedness problem for decades. There are tens of thousands of these multi-family three- and four-story structures throughout California and other cities in the United States. The majority were constructed between 1920 and 1970, with many being prevalent in the San Francisco Bay Area in California. The NEES-Soft project was a five-university multi-industry effort that culminated in a series of full-scale soft-story wood-frame building tests to validate retrofit philosophies proposed by (1) the Federal Emergency Management Agency (FEMA) P-807 guidelines and (2) a performance-based seismic retrofit (PBSR) approach developed within the project. Four different retrofit designs were developed and validated at full-scale, each with specified performance objectives, which were typically not the same. This paper focuses on the retrofit design using cross laminated timber (CLT) rocking panels and presents the experimental results of the full-scale shake table test of a four-story 370 m2 (4000 ft2) soft-story test building with that FEMA P-807 focused retrofit in place. The building was subjected to the 1989 Loma Prieta and 1992 Cape Mendocino ground motions scaled to 5% damped spectral accelerations ranging from 0.2 to 0.9 g.
TL;DR: In this paper, the authors proposed a method to reduce the risk of tornado damage by understanding the wind loads and developing methodologies to reduce wind loads in the presence of severe weather events.
