Composite structures are gaining in importance in Europe. The combination of materials within its specific properties results in very slender and economic constructions. Composite girders permit large spans in slender frame bridges without loss of economy. Due to the high grade of prefabrication in building construction smaller survey heights and shorter construction times are possible.
The enduring bearing capacity of composite girders depends on the performance of material and the design of shear connection. A new form of shear transmission - the concrete dowel - permits composite girders without an upper steel flange and an enduring shear connection also of high strength steel with high strength concrete.
The PrECo-Beam construction and its application are comparable to existing prefabricated composite systems. With a high surface durability and less sensitivity for fatigue the system comprehends long-lasting advantages. The modular composition moves principal works for the structures and multi-storey building from the site into the workshop, reduces the construction time and improves the quality to reduce maintenance costs.
