If theattention is focused on the structure, optimality is mainly sought through improvement of the form 1999 by CRC Press LLCcand of the materials. Moreover, creative innovation of the form combined with advances of materialproperties and technologies enables pursuit of the human challenge to the “natural” limitations tothe height (buildings) and span (roofs and bridges) of the structural systems. Advances may be seen to occur as a step-by-step process of development. While the enhancementof the properties of already used materials contributes to the “in-step” continuous advancement, newmaterials as well as the synergic combination of known materials permit structural systems to makea step forward in the way to optimality. Use of composite or hybrid material solutions is of particular interest, due to the significant potentialin overall performance improvement obtained through rather modest changes in manufacturingand constructional technologies. Successful combinations of materials may even generate a newmaterial, as in the case of reinforced concrete or, more recently, fiber-reinforced plastics. However,most often the synergy between structural components made of different materials has shown to bea fairly efficient choice. The most important example in this field is represented by the steel-concretecomposite construction, the enormous potential of which is not yet fully exp ...
