This building will be housing two different Marriot hotels, the Courtyard and the Fairfield. The whole building will be constructed on top of a large new mall called Via Vallejo, located in the centre of Mexico City.
The 10-floor building will has been designed to not only withstand the effects of the severe earthquakes in Mexico City, but also to ensure the serviceability of the hotel during and after the seismic event. To do this, the engineers have chosen to use seismic isolation as a protective strategy.
To improve the seismic response of the building, the engineers in charge of the structural design performed complex dynamic analysis, which confirmed that the best strategy was to seismically isolate the hotel from the large mall. Therefore, it was decided that 18 mageba LASTO-LRB (Lead Rubber Bearings) will be supporting the entire hotel. These devices will isolate the structure, which is rather flexible, from the much stiffer mall’s structure.
This strategy has been confirmed after extensive three-dimensional dynamic analysis of the structure seismic response.
