A unique building project that includes office space, shopping malls, a luxury hotel, restaurants, sports grounds and panoramic observation decks. This building is the second tallest building in the Russian Federation. The design is complicated since the building is located in earthquake-prone zone with a probable intensity up to 9 points. The design of the AKHMAT TOWER required a thorough analysis of structural stability, wind load resistance, seismic resistance and other technical aspects. The team has developed innovative solutions to ensure the safety and sustainability of the building. The high-rise building resembles the appearance of the Chechen medieval watchtowers.

The tower's lateral load bearing system is concentrated on the building perimeter and consists of load-bearing columns made of high-tensile steel with a grid of 4.5 meters, connected by special 1 meter high steel crossbars  along the building perimeter on each floor. Together, the columns and crossbars form a highly ductile (elastic) frame structure. Super high-tensile steel was used to optimize the column structures dimensions and reduce weight. Highly elastic steel is used for the crossbars. In structures up to the 40th floor, composite cross-section technology is used – filling columns with high-tensile concrete connected with metal columns in a single section.

Building height: 435 m

Design work performed by our team:

• performing joint calculations of the load-bearing building framework and the ground mass in a non-linear positioning including special effects: seismic impact of the "design earthquake" and "maximum calculated earthquake" levels;
• development of the reinforced concrete structures section during the WD and PD stages for the following structures:
• pile foundation of the high-rise part;
• monolithic reinforced concrete foundation of the high-rise part;
• all loadbearing structures of the underground part;
• conducting author supervision
