Abstract
- Translation abstract <bold>Application of the new THG guideline of the DAfStb for the evaluation of practice‐relevant slab systems using solid structures</bold>The German Federal Government intends to achieve greenhouse gas neutrality by 2045. In this context, the German Committee for Structural Concrete (DAfStb) has specified in a technical guideline a set of reduction classes (TM) for the greenhouse gas emissions of structural systems. However, the wide scope of the design space means that, in practice, it remains challenging to design for minimal or reduced greenhouse gas emissions without any loss of structural performance. As the possibilities for reducing emissions in the construction of load‐bearing structures are greatest in the early design phase, three different solid floor systems are evaluated in this study with regard to their greenhouse gas emissions and fulfilment of the TM. To this, the design approach varies alongside span widths, loading conditions and concrete classes with different cement mixtures. The results indicate that the combination of modern cements with optimised design approaches offers great potential for emission savings. The classes up to TM‐30 defined in the technical guideline can be achieved with conventional solutions such as cast‐in‐situ concrete floors. If TM‐40 or TM‐50 is to be achieved with non‐prestressed systems, the design and choice of cement must be optimised. For larger spans and higher TM, optimised floor systems, such as prestressed hollow core slabs, must be selected in combination with modern cement mixtures. [ABSTRACT FROM AUTHOR]
