![]() The ‘Guideline for the Reuse of Structural Load-Bearing Elements’ is now available! Our project team is excited to announce the publication of this guideline. The new guideline for the reuse of structural load-bearing elements offers planners valuable support in the environmentally friendly and building law-compliant reuse of steel and timber components. It contains practice-orientated methods for the dismantling, preparing and reintegration of structural components as well as regulatory recommendations for implementation in accordance with German building law. The guide shows that the reuse of structural components is not just feasible, but also regulation-compliant - a crucial step towards promoting sustainable building practices in the construction sector. The full guideline and accompanying research report are now available. Download via KIT Library |
![]() KIT Timber Structures has been researching timber construction for over a century. When Philipp Dietsch took office, he committed himself to digitizing all research reports, dissertations and proceedings of our institute and making them freely accessible. Today we are delighted that this mission has been fulfilled! The digitization was time-consuming, but the result is worth it. You can download original works such as Karl Möhler's habilitation (1956) or Hans Joachim Blaß' dissertation (1987) from our website. You will also find conference proceedings from 52 years of INTER / CIB W-18 and 25 years of Karlsruher Tage. Discover the entire archive here: https://holz.vaka.kit.edu/19.php Post on LinkedIn |

In collaboration with KIT and the Technische Universität München (TUM), this guideline aims to provide actionable steps for reusing structural building components, helping to conserve resources in construction. |
![]() A lot has happened since the last Karlsruher Tage: resource-efficient construction, detachable connections and the reuse of components have long been part of everyday life, and "Tall Timber" is common practice. Special thanks go to the speakers whose presentations realised the motto "Research for practice". The event was a success thanks to your participation and the dialogue between colleagues. The positive response encourages us to organise the Karlsruher Tage again in two years' time - with the traditional closing in the laboratory. Post on LinkedIn |

![]() Modern adhesive technology now enables bonding steel profiles to timber beams without premature timber failure under significant bending loads. Our large-scale 4-point-bending tests show improvements in bending stiffness (up to 250%) and load-carrying capacity (up to 120%) compared to traditional glulam beams. These findings suggest competitive and resource-efficient solutions, particularly for multi-storey buildings requiring large floor spans. This paper provides simple engineering calculation models for reliable design of this innovative solution: doi.org/10.3390/ma17051164 LinkedIn |

![]() This week, as part of the 2022 construction competition at the Karlsruhe Institute of Technology (KIT), we organised the "bridge out of the bag" construction competition. In this competition, the students had to build a bridge with a span of 3 metres. This bridge had to fit into a bag 1 m high. The bridge had to be assembled on site within 30 minutes. In the first test, the bridge had to withstand a moving load (Prof Dietsch). In the second test, the bridge had to collapse under a predefined load (all group members). LinkedIn |
![]() It was a great pleasure for us to present our results and innovations from the pan-European CLT project, InnoCrossLam, live to the wood community at the ForestValue Conference in the Sara Cultural Centre, Skelleftea. In this context, we were able to collect the most important future topics for solid wood construction from the experts present. Despite corona, our research group has really grown together and we look forward to continuing to work with these outstanding researchers. LinkedIn |
![]() A test method was developed to evaluate the feasibility of inserting small diameter fasteners, like nails and staples, into non-pre-drilled hardwood. Suitable fasteners from this study were tested to validate design models. Results indicate existing softwood design models are transferable to hardwood. High-density hardwood causes new failure types, leading to an analytical design model currently being validated. Innovative test setups measuring normal forces along the anchor axis showed increased load-bearing capacities. Self-drilling screws, particularly effective along their axis, also showed higher stiffness and capacity. The study focused on bolt group connections, developing user rules for reliable design and load calculations. Numerous test series validated these models, confirming that existing design models for staples and nails are applicable. Proposed regulations include increasing minimum screw spacing to 8d in the fibre direction and pre-drilling screws. Find here the final report |
