Con una altura máxima de 190 m, las Torres Bakú Flame se encuentran entre las estructuras más altas de Azerbaiyán. Se trata de un proyecto realizado por HOK Arquitectos. La construcción debió detenerse varias veces, obligando a los ingenieros a luchar contra los frecuentes vientos huracanados de Bakú, sin dejar de tener en cuenta la actividad sísmica de la zona. Debido a estos fuertes vientos, algunas partes de la construcción fueron realizadas sin el uso de grúas.
Las torres crean una formación triangular unida entre sí por una base formada por un podio ondulante. Las formas curvas de las torres terminan en punta y se curvan alrededor de los jardines del techo, proporcionando una medida de protección.
El complejo está formado por tres torres que comparten un podium común que actúa como ancla de todo el proyecto, proporcionando instalaciones comerciales y de ocio para residentes y visitantes. Cada una de las torres tiene un uso diferente: la Torre 1 es totalmente residencial, la Torre 2 es un hotel y la Torre 3 es un edificio de oficinas.
Los principales sistemas estructurales de las tres torres están levantados con hormigón armado. En cambio, los pisos de la parte superior de las torres se construyeron con marcos filigrana en acero.
El marco primario de las agujas consiste en un marco especial con tres articulaciones construido con tubos redondos de 610 mm de diámetro. Siguiendo la geometría del diseño, para la construcción se utilizaron secciones curvadas biaxialmente de los tubos, soldando los puntos de conexión. Para reducir las deformaciones de la construcción, de 30 metros de altura, las columnas de acero verticales, en los laterales, se unen al bastidor mediante conexiones con resistencia a flexión. Una sección transversal triangular especial, hecha con típicas chapas y barras redondas de acero fue utilizada para estas columnas de modo que permitieran una vista hacia el exterior lo más amplia posible.
Para soportar las cargas de viento, se necesitaron diagonales adicionales en la parte lateral posterior curvada de las construcciones de acero, a fin de reducir la deformación total en la aguja de las torres a la requerida de 90 mm.
Los materiales principales utilizados para la estructura fueron hormigón armado y tubos de acero de 6,10 cm de diámetro.
Las fachadas están totalmente acristaladas y utilizan una mezcla de cristales tintados de color naranja y azul. Además, las fachadas están completamente cubiertas con pantallas LED, con más de 10.000 luminarias, que muestran el suave movimiento de las llamas, visibles desde los puntos más alejados de la ciudad. Esta iluminación crea el efecto de las antorchas gigantes que enfatizan la idea principal de las Torres incorporada en su nombre (Torres Llama de Bakú). Por la noche, sus exteriores LED se encienden para representar las llamas, una bandera ondeando de Azerbaiyán y otras imágenes en movimiento.

With a maximum height of 190 m, the Baku Flame Towers are one of the higher structures of Azerbaijan. It's a project by HOK architects. Construction was stopped several times, forcing engineers to combat the frequent winds of Baku, while taking into account the seismic activity in the area. Because of these strong winds, some parts of the construction were carried out without the use of cranes.
The towers create a triangular formation joined each other by a base formed by an undulating podium. The curved shapes of the towers end up on tip and curve around the gardens of the roof, providing a measure of protection.
The complex consists of three towers that share a common podium that acts as an anchor of the whole project, providing entertainment and a shopping centre for residents and visitors. Each of the tower has a different use: Tower 1 is completely residential, Tower 2 is a hotel and Tower 3 is an office building.
Major structural systems of the three towers are raised with reinforced concrete. On the other hand, floors from the top of towers were built with filigree steel frames.
The primary framework of the spires is a special frame with three joints constructed with round tubes of 610 mm in diameter. According to the geometry of the design, in the construction were used sections biaxially curved of the tubes, welding connection points. To minimize deformations of the building, 30 meters high, vertical steel columns, on the sides, were joined to the frame by means of connections with flexural strenght. A special triangularcross section, made with typical metal sheets and rods of steel, was used for these columns so that to allow a view out the widest possible.
To withstand wind loads, additional diagonals were needed in the curved back side of steel constructions, in order to reduce the total deformation in the spire of the towers to the required 90 mm.
The main materials used for the structure were reinforced concrete and 6.10 cm diameter steel tube.
The façades are fully glazed and used a mixture of orange and blue tinted glass. Moreover, the façades are completely covered with LED screens, with more than 10,000 lights, showing the gentle movement of the flames, visible from points further away from the city. This lighting creates the effect of giant torches that emphasize the idea of towers, incorporated in their name (Baku Flame Towers). At night, its external LED are lit to represent the flames, a waving flag of Azerbaijan and other moving images.
