Blown away: Citicorp Center Tower repairs revisited.
Using Database-Assisted Design and the Tokyo Polytechnic University Aerodynamic Database, we show that face winds put more structural demand than corner winds do on the Citicorp Tower in Manhattan. This 59-story building, supported by four midside columns, famously had to undergo secret emergency strengthening shortly after its completion in the 1970s to withstand corner winds.
