摘      要：The Mexico City Building Code (MCBC-2004) - Reglamento de Construcciones del Distrito Federal, Gaceta Oficial del Distrito Federal, 29 de enero de 2004 in Spanish - is a state-of-the-art code;the most comprehensive and advanced set of requirements in the country;and it serves as a model for codes in Mexico s regions. However, many recently built mid-rise dwellings seem too weak to withstand earthquakes, with evident structural deficiencies. Insufficient official mechanisms exist for supervising the design and construction of such new structures. This study evaluates current practice and compares it with the guidelines of the MCBC-2004 using a sample of structures of 150 buildings constructed after 2004. Structural analysis and design revisions were made for a subset of 20 buildings. This study confirms that a large number of new buildings in Mexico City do not have a reliable record of technical information. Therefore, it is difficult to reanalyse buildings to assess their earthquake performance. Many buildings have limited information making it impossible to verify their structural seismic behaviour. The analyses performed for those buildings with available information show that many would have inadequate performance during an intense earthquake, as they do not meet the minimum requirements in the MCBC-2004. To improve governance and actual outcomes, an institute is needed to improve construction practices and code enforcement particularly for residential buildings.
