        Launch of the new ZIM project LeNa

        Together with the Chair and Institute of Construction Management, Digital Construction and Robotics in Civil Engineering (RWTH Aachen University) as a project partner, SDA-engineering GmbH is launching the three-year project "Development of a software tool for the automated and cross-life cycle sustainability assessment of masonry structures" (LeNa) (FKZ: 16KN116121).

        The innovative research project within the sustainable masonry network aims to develop a software tool with AI support that enables automated sustainability assessments for masonry structures over their entire life cycle. The tool uses Building Information Modeling (BIM), digital material passports and new distributed databases to link sustainability-relevant data directly with geometric building data. It automates key processes such as statics, energy efficiency and sound insulation, taking into account interactions between different building properties. The tool is initially designed for the sustainability optimization of single and multi-family homes with up to six storeys. The tool reduces the time required for a sustainable planning process and allows planning variants to be evaluated quickly and efficiently.

Its purpose is to ensure that in the event of earthquakes human lives are protected, damage is limited and structures important for civil protection remain operational. Prof. Butenweg is the coordiantor and Ass. Prof. Marko Marinkovic the chairman of the webinar​​​. Detailed information are provided on the EAEE website

                  Earthquake mission to the crisis area in the south of Turkey

The mission have focused on earthquake damage to reinforced concrete and masonry buildings, infrastructural buildings and industrial facilities. The mission was followed by SRF - Schweizer Radio und Fernsehen. The mission was joined by the Turkish colleagues, Dr. Şerife Özata and Dr. Zeynep ÜNSAL ASLAN, who supported the mission with their knowledge of the regional building stock and communicating with the local population. The damage evaluation will be shared soon in publications and presentations.

                  Engineering Research Infrastructure For European Synergies - SERIES: Evaluation of flexible and sliding joints for seismic-resilient design of masonry-infilled RC frames (FLEJOI)

                  The proposed project FLOJOI (Horizon Europe Framework Programme Ref: 101058684-HORIZON-INFRA-2021-SERV-01-07) aims to evaluate the effectiveness of two different systems based on flexible joints for protecting masonry infills and improving the seismic performance of reinforced concrete (RC) buildings equipped with them in shaking table tests. The shaking table tests will be carried out at out at IZIIS in Skopje for the illustrated test structure. The first one is a compliant system based on horizontal joints developed by TARRC placed within the panel, and vertical rubber joints placed between the panel and the frame columns. The second one (INODIS) is a decoupling system with sliding/flexible joints placed at the frame-infill interfaces. The effectiveness of the two systems for the infill protection was proved within past tests, but only under quasi-static conditions. The FLEJOI project will unlock the potential of flexible joints for the resilient based design of infilled RC frames. It will provide key data for validating modelling strategies and informing the development of design methods and recommendations for the new generation of anti-seismic codes. This will ultimately have a transformative impact on how RC buildings are designed and constructed. The User Group (UG) is constituted by 17 researchers and industry consultants from different organisations across 5 countries. The German partners are SDA engineering GmbH, the Bundesverband der Deutschen Ziegelindustrie e.V., Fachgruppe Hintermauerziegel and the Center for Wind and Earthquake Engineering at RWTH Aachen University.

                  SDA is a member of the Sustainable Masonry Innovation Network

                  The vision of the sustainable masonry innovation network is to significantly increase sustainability in masonry by developing new processes and products. All three pillars of sustainability are to be taken into account: Ecology, economy and social aspects. Only by taking all aspects into account can today's challenges be solved in the long term. The "Sustainable Masonry" network pools existing expertise in planning, construction and dismantling using different types of masonry blocks. By bringing together small and medium-sized companies in the innovation network, synergy effects are optimally used to drive forward innovative developments.

                  DEMAS (ZIM project)

                  The aim of the DEMAS project (project duration 01.08.2022 to 31.07.2024) is the development of dissipative elements for decoupling and securing non-load-bearing walls in multi-storey buildings. The project is financially supported by the Central Innovation Program for SMEs (ZIM) of the BMWK - Innovation Networks.

                  Worldwide, more than two billion people live in earthquake-prone areas. However, many of them do not live in appropriately earthquake-proof houses. Since it is not possible to predict earthquakes precisely, the only way to increase resistance and thus protect numerous lives is the protection of buildings through adequate measures. The main cause of damage to reinforced concrete frame structures is full contact between the reinforced concrete frame and the infill masonry, so that an earthquake usually results in activation of the infill and uncontrolled load transfer to it.

                  By developing universal as well as scalable dissipative elements, it should for the first time be possible to decouple the deformations of infill masonry and reinforced concrete frames. In addition, the novel decoupling elements are to enable a safer connection of non-load-bearing partition walls to floor slabs. The novel connection elements prevents the load transfer from the structural system to the infill masonry and improves the resistance of multi-storey buildings. The decoupling elements are intended to provide a decoupling of the infill masonry, especially in the case of combined loads (in and perpendicular to the wall plane). Due to their scalability, the elements are to be used for any wall geometry and masonry unit type and can be easily installed on site.

                  SDA starts ZIM project Dynamic BIM

                  Together with the Chair of Structural Analysis and Dynamics (RWTH Aachen University) as project partner, SDA-engineering GmbH starts the two-year project "Development of a BIM-integrated damage analysis for dynamic building data" (FKZ: 16KN093523).

                  The aim is to develop a digital method for continuous dynamic monitoring of structures. Dynamic effects on structures can limit their serviceability and cause massive damage, resulting in considerable costs. Continuous and automated monitoring of the dynamic conditions of structures using sensors and coupling the recorded data with BIM (Building Information Modeling) allows to simulate and interpret structural vibrations in near-real time. In this way, critical movements and changes in the structure of the building can be detected directly and structural dynamic upgrades or rehabilitation measures can be made possible at an early stage.
