This paper presents the challenges encountered during the structural design of a high-rise building located in a seismic area. The construction is an office building, it has 20 stories including the basement levels and a narrow base. Some of the challenges are: providing an accurate structural system to resist the wind and earthquake actions and to design a proper foundation to avoid the overturning of the entire structure. Another important aspect is to limit the stories drift but at the same time provide an open space for the office area. Hybrid structures do not behave like reinforced concrete structures in the sense of Eurocode 2 nor like composite structures in the sense of Eurocode 4. For this reason and due to the lack of knowledge related to the problem of force transmission between steel and concrete the design of structures with hybrid steel-concrete elements can become very difficult. Several models are analysed comparing structural systems made of reinforced concrete, ones made of hybrid steel-concrete elements and several other types of systems.
