Summary

This paper highlights the analytical and design procedures used in the retrofitting of the Azadi Hotel building, which is located in Tehran. The building was constructed of concrete and the main lateral load carrying elements are the concrete cores. As with many other hotels built in the 1970s, the major deficiency was the existence of a soft storey in the lobby, including poor quality concrete columns of up to 11 meters high. The main challenge in retrofitting this building was the inability of the engineers to intervene largely in the lobby. In order to prevent overturning of the structure, and reduce moments and shears at the base, sixteen hydraulic dampers were utilized in the lobby and first floor. More than 20,000 meters of fiber reinforced polymer was also used to reinforce the columns and the cores in the lobby and the two basement floors. The dampers also, were installed with help of inverted V-bracings. Soil-structure interaction was considered in the retrofitting analysis of the building. The nonlinear transient finite element method and cone model have been applied to the three dimensional model of building for seismic response analysis.
