Cyclones, typhoons and hurricanes are the same natural threat, but are called by different names and rotate in different directions in different locations around the world. The two-year long CTBUH research project, “Cyclone-Glazing and Façade Resilience for the Asia-Pacific Region,” initially focused on 12 Asian jurisdictions, which are hit practically every year. By 2016, there were 4,569 tall buildings in cyclone-prone areas throughout these 12 jurisdictions. The research activities highlighted the local or international code and standard requirements for the design and the construction of cyclone-resistant façades in these areas. Then, a comparison between the Asia-Pacific construction requests for the glazed building envelope and the US product-approval process was conducted. In the US, several post-disaster assessments proved the effectiveness of domestic cyclone-resistant glazing solutions, but this has not translated internationally. Most of the Asia-Pacific cyclone-prone jurisdictions analyzed do not have any specific requirement for their curtain walls.

The second stage of the research deeply investigated best practices when it comes to the design, the construction and the post-event inspection of strong-wind- and cyclone-resistant façades in Australia, Hong Kong, Japan, and in the Philippines. A case-study collection is presented, which gives an overview on the different approaches to the problem in the four jurisdictions. This will be summarized in a technical research report as well.
