Composite beams
A composite beam consists of a combination of a steal beam andconcrete or reinforced concrete connected in a shear-resistant manner so that they act together as a single structural member.
Composite beams have much higher resistance values than pure steel or pure reinforced concrete beams and hence allow for thinner cross sections or larger spans with lower beam thicknesses.
Regulatory framework
DIBt grants general construction technique permits (aBG) for the design and execution of composite steel and concrete beams where the design resistance values are not calculated in accordance with Eurocode 4 (DIN EN 1994), but design assisted by testing is used.
For non-regulated construction products used in these construction techniques, DIBt grants national technical approvals (abZ) also in combination with the general construction technique ('combined decision'). European Technical Assessments (ETAs) can also be issued for the related construction products.
Please also refer to the applicable design and execution rules, cf., in particular, MVV TB, Parts A 1 and A 2.
National procedure
A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.
No formal requirements apply. The following information is needed: name and address of the applicant, description of the product and/or construction technique and its field of use or application, type of decision required (new decision, amendment or supplement to, or renewal of, an existing decision).
