Since coming into force of the European standards for the assessment of masonry structures as for the assessment subjected to earthquakes (EN 1996, EN 1998) all buildings, also existing buildings, are subject to these regulatory rules and regulations. Buildings of the 19th and the early 20th century were mainly produced of brickwork. These buildings normally do not comply with the regulations included in the standards, whereby attempts for the introduction of special methods of calculations for the rebuilding of existing housing stock (e.g. various regulations of the MA 37, respectively MA 37S in Vienna) were made. A common regulation from an instruction sheet of the municipal building inspection demands a preservation of the existing level of capacity for the evidence of earthquake. But these exceptions are only permissible for refurbishments in a limited extent. On 1st May 2013 with the ONR 24009 -Evaluation of the load-bearing capacity existing buildings- a new set of regulations became law. In conjunction with the revised ÖNORM B 1998-3 these guidelines present a now comprehensively usable tool for engineering. Referring to umpteen attempts in literature various attempts with concrete prisms of SHCC were performed. For this purpose before a suitable SHCC concrete mixture was originated and exactly adjusted for the requirements. The aim is, to achieve a distinctly ductile reaction on flexural tension- and normal force load here, as well as to obtain high energy dissipation during the load history. Besides considerations for the stability of the thin shear walls were made.
