This seven-story (44,000 ft2, 125 ft height) reinforced concrete framed building was designed in the early seventies. Although it suffered only minor damages during the great Michoac‡n Earthquakes of 1985, new code requirements for the city called for a structural evaluation of its safety. Previous owners contracted a new study that was delivered in 1989. As the work for this strengthening scheme progressed through the foundation, new private owners asked associates of LCR&A to evaluate the original building, its recently strengthened foundation system, the planned superstructure solution, and possibilities for any other alternative strengthening designs for the superstructure. Several investigations and analysis were performed and an alternative solution based on a combination of stiffening members and prescription for energy dissipation schemes was presented. A full set of specific detailed drawings, a book of construction specifications, and a summary report were prepared. Considerable savings of construction costs were incurred by the new owner.
