Abstract
Ein Blick in die Baugeschichte zeigt, dass sich in Abhängigkeit der vorhandenen Baumaterialien jeweils typische, sinnvolle Konstruktionsformen herausgebildet haben. Bereits vor mehr als 10.000 Jahren errichtete man Gebäude aus Ziegelmauerwerk [1]. Im antiken Rom erlebte der opus caementitium seine Glanzzeit [2]. Beide Materialien sind sehr druck-, aber wenig zugfest. Folglich findet man hauptsächlich druckbeanspruchte Strukturen wie Wände oder Kuppeln, für Decken wurde beispielsweise Holz genutzt. Für Naturbrücken aus zugfesten Pflanzenmaterialien hingegen sind Hängekonstruktionen prädestiniert. Mit Stahl und bewehrtem Beton können auch biegebeanspruchte Konstruktionen realisiert werden. Allerdings nimmt man hierbei in der Regel in vielen Tragwerksbereichen eine mangelhafte Materialausnutzung in Kauf.
A look at the construction history shows that typical, sensible forms of construction have developed depending on the building materials available. More than 10,000 years ago, buildings were already made of brickwork [1]. In ancient Rome, the opus caementitium experienced its heyday [2]. Both materials were very resistant to pressure, but had little tensile strength. Consequently, one mainly finds structures subject to compressive stress such as walls or cupolas; for ceilings, for example, wood was used. For natural bridges made of tension-resistant plant materials, on the other hand, suspended structures are predestined. With steel and reinforced concrete, structural elements subject to bending stress can also be realised. However, in many areas of such structures, insufficient utilisation of the material is accepted.
