Seismic Design of the Tallest Building in Mexico

Abstract eng:
Growing urban sprawl in Mexico’s largest metropolitan areas is beginning to have a negative impact on the way people work and live. The desire to be closer to work and public amenities is resulting in the need to build taller in city centers. Many cities in Mexico are seeing an increase in the number of tall buildings, including Monterrey, the second largest city in Mexico. Torre Koi, a mixed use high rise in Monterrey, at 279 meters tall and the tallest building in Mexico, is a recent example. Until a minor earthquake was experienced in 2013, Monterrey was considered to be a non-seismic zone. The local building code in Monterrey does not cover seismic design of structures, not to mention the seismic design of tall buildings. The design team referred to the Federal Electricity Commission’s Manual de Diseño de Obras Civiles (CFE Manual) for seismic design procedures as a prudent way to address potential seismicity. This paper will discuss the seismic analysis and design procedures employed on the high-strength concrete core and virtual outrigger structural system utilized on the tallest building in Mexico.
