Reinforced-concrete beams in building construction and civil engineering

Ultra-light beams as concrete-steel hybrid

Reinforced-concrete beams are widely used in building construction and civil engineering. They often have full rectangular cross-sections which is advantageous for both the simple production on site and as precast element; however, it involves high dead weight and material input simultaneously.

Concrete structures are not a priori linked to geometries and can be designed in almost any shape. Shapes following the flow of forces lead to slender and aesthetic structures, which rapidly decrease the material consumption [1]. The same applies to the reinforcement, which favorably is to be installed...
