Colombia is facing a continued surge of tourism into the country and Colombia’s airports are preparing major expansion plans to deal with it. One of the modernised airports is the Cartagena Rafael Núñez International Airport located in Crespo, part of the Caribbean coastal city of Cartagena De Indias. With over three million passengers annually, Rafael Núñez is Colombia’s third largest airport. Due to its appealing location, the city attracts a growing number of tourists and businesses, requiring an expansion of the airport to absorb up to 8.5 million passengers per year.
For this purpose, the international terminal building has been designed that will connect to a new boarding pier, spanning over more than 400 m. The total designed area of this new expansion is 27,000 m2.
The project challenges
The engineers faced several challenges:
- the complex geometry of the steel roof with 3D and 2D truss girders,
- combination of parts made of different materials,
- need for several advanced types of analysis.
“SCIA Engineer proved to be very flexible with data input, obtaining more productivity than with any other structural software used in the company.”

Advanced analyses and hybrid structure with SCIA Engineer
The principal structure of the terminal was modelled directly in SCIA Engineer. It is a single building of more than 5,600 m2. It has a steel roof composed of several spatial and planar trusses made of tubular Hollow Structural Section, forming different inclinations on the roof. Also, the façade was modelled in SCIA Engineer. In terms of analysis and verification, the broad functionality in SCIA Engineer proved to be very useful:
- advanced analysis with local non-linear considerations,
- second order analysis,
- tension-only elements,
- physical non-linearity of the concrete material,
- advanced dynamic and seismic analysis.
In addition, the steel and concrete code-checks according to AISC and ACI were performed in SCIA Engineer.
“This complex project was modelled directly in SCIA Engineer as a hybrid structure with a span of over 400 meters, including façades and roof. The jury was impressed by the advanced analyses with second order, tension- only elements, physical and geometrical non-linearities, as well as advanced dynamic and seismic calculations, resulting in a fabulous building.”
