Automated construction of calcium silicate masonry using cable robots Cable robots represent an innovative and auspicious approach to digitisation and automation in construction and bear the potential to revolutionize the handling of masonry bricks. The use of cable robots allows for installing large construction volumes and even realizing complex geometries within short time and reduced personnel deployment. In the long term, this will not only increase productivity in construction companies, but will also counteract the lack of qualified craft workers and improve the image of the industry as a whole. The practical implementation of digitisation and automation in masonry construction using cable robots is current work of a consortium formed by the research association Forschungsvereinigung Kalk-Sand e.V., the Chair of Mechatronics and the Institute for Construction Operation and Management at the University of Duisburg-Essen as well as the IAB – Institut für Angewandte Bauforschung Weimar gGmbH. The following article provides an insight into the development of a cable robot prototype which is realized to demonstrate the automated bricking of a single-storey building.
Due to the current importance of sustainability, the federal association of the calcium silicate masonry unit industry has taken intensive interest in the question of the resource efficiency of calcium silicate masonry units and construction and has carried out an extensive investigation to this end. The study subjected all stages of calcium silicate, from raw materials reserves and their extraction, production and use in building to recycling, including all transport routes and energy demands, to detailed analysis and critically examined the sustainability of calcium silicate blocks. The present article explains and evaluates the entire life cycle of calcium silicate masonry units.

Following the publication of the National Annex to Eurocode 6 Part 1-2 in June 2013, all documents are now available for the structural fire design of masonry in accordance with the Eurocode. As Eurocode 6 has been declared of equivalent value by the Expert Commission for Construction Technology, it is now ready to be applied in Germany. In spite of the changeover to the European concept, including the introduction of newly defined fire resistance classes, the Eurocode 6 tables for determining the duration of fire resistance as a function of the wall thickness are nearly unchanged compared to the familiar values in DIN 4102-4. The few changes and adaptations to the current state of technology are discussed here and explained. The emphasis of the new approach is that the changed vertical loadbearing capacities -in accordance with EN 1996 - and their effect on fire resistance are taken into account.
AbstractDIN EN 1996‐1‐2 schreibt in Verbindung mit dem nationalen Anhang den bekannten Status von DIN 4102‐4 im Wesentlichen fort. Dieser Beitrag erläutert die neu definierten Ausnutzungsfaktoren sowie die Regelungen in bauaufsichtlichen Zulassungen und zeigt das einfache, grundsätzliche Vorgehen bei der Brandschutzbemessung anhand von Beispielen.Structural design of masonry for fire resistance according to DIN EN 1996‐1‐2/NA and according to general technical approvals. The well known rules for fire design from DIN 4102‐4 are transferred with no major differences to DIN EN 1996‐1‐2 together with the corresponding National Annex. This paper highlights the definitions of the new utilization factors as well as rules in the relevant national technical approvals. Examples show the practical fire design with tabulated data according to the new standard.
