To reduce the horizontal deformations, it would be necessary to increase the lateral stiffness. However, this would in turn result in an increase in seismic forces. The solution presented here therefore represents a good compromise between the two strategies. 4. Execution Figure 7 shows the 3 reinforcement measures to ensure the earthquake resistance and the overall structural integrity of the HOF building. In addition to the two frames A and B, additional struts were installed in the roof structure to ensure the diaphragm behavior.

Figure 8 show the installation process of the steel frame A within the courtyard and the additional braces installed within the top story to ensure a sufficient diaphragm action in the steel structure.
