The “Central Tuxtla I” building houses telecommunications equipment and antennas in charge of all calls that are made from the city of Tuxtla Gutiérrez (capital of the State of Chiapas) to México City and to interior cities of the Republic of México. This seven-story (28,000 ft2, 125 ft height) reinforced concrete framed building was designed in the late sixties. Its location in a severe seismic zone as well as its geometric configuration generated a concern to the owners. The building was studied in its existing condition and in several possible strengthened configurations. The close presence of neighboring structures further limited the possibility of alternative strengthening schemes. A solution involving the addition of deep foundation members, and a strengthened superstructure was prepared by associates of the LCR&A team. Basic studies of soil-structure interaction were necessary. A complete set of construction drawings, specifications and a final report were delivered to the client.
