Punching shear reinforcement

Punching shear reinforcements are special reinforcements used in place of stirrups or bent reinforcements to increase the punching shear resistance of beam supports for reinforced concrete floor slabs. Examples of punching shear reinforcements are double-headed studs and lattice girders.

Regulatory framework

DIBt grants national technical approvals (abZ) for punching shear reinforcements which

  • significantly deviate from the Technical Building Rules (cf. MVV TB, Part C2) or
  • for which neither Technical Building Rules nor generally recognised technical rules exist.

European Technical Assessments (ETAs) can also be issued for punching shear reinforcements.

Furthermore, DIBt grants general construction technique permits (aBG) for construction techniques comprising shear reinforcements for which there are no conclusive technical rules.

Examples include wall and floor construction techniques.

Please also refer the applicable product, design and execution rules, cf., in particular, MVV TB, Part A 1 and Part C 2, as well as the following information and technical rules.

Application forms

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).

European Technical Assessment (ETA)

To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
