Innovation in steel frameworks

Constant Compex is working side-by-side with engineers specialized in design and installation of structural frames made of steel frames. Steel is a highly durable material that allows the construction of supporting columns and beams capable of bearing the weight of large tall buildings.

Steel frame structures minimize the thickness and width of the structural elements on the building’s perimeter, thus allowing large openings that can be plated with solid material of lesser weight than load-bearing masonry. Structural systems for tall buildings can be divided into three categories: indoor and outdoor structures or mixed, based on components distribution of primary system resistant to lateral force on the building. Each system has a wide range of applications in height depending on criteria such as shape, loading, stability, appearance and architectural proportions.

Reinforced concrete frame-type structures provide flexibility in floor partitioning and are easy to build. They consist mainly of slabs, beams and pads. They are used in the construction of buildings with a large number of stories in regions with high seismicity, and closures and walls are typically done in AAC (autoclaved aerated concrete) or brick. Structural systems for multi-storey buildings located in seismic zones must have corresponding strength, stiffness and ductility in order to have an adequate response in case of strong seismic movements.

Among the advantages: great capacity to takeover of gravitational and horizontal loads, flexible organization of space, interior walls of lightweight material (drywall, AAC, etc.), option to externally seal with any type of material, ample space configurations etc.

A very important feature of metallic structures is their versatility, adaptability, their ability to be changed and reconstructed. Steel parts are prefabricated to industry standards, they are easy to transport and quick to install, low cost and with fairly low reliance to environmental factors as compared to concrete structures.

Under proper maintenance, metal constructions are highly durable and pass the test of time. Protective and maintenance measures against corrosive elements include the possibility to zinc-coat by heat-processing those structures directly exposed to atmospheric conditions, the effects of fire are counteracted by applying heat-resistant paints (intumescent paints), insulating mortars, concrete cladding or embedding.

• Height - determines the type of structure
• Use of the building - determines vertical and horizontal subdivision to ensure operating conditions and comfort
• Building site - influences the type of foundation and building height
• Building materials
• Execution technology
