SDA is represented at the 18th D-A-CH conference as a supporting member of the German Society for Earthquake Engineering and Structural Dynamics (DGEB). The conference is organized by the DGEB in cooperation with the Austrian Society for Earthquake Engineering and Structural Dynamics (OGE) and the Swiss Society for Earthquake Engineering and Structural Dynamics (SGEB). The biennial event provides an opportunity for civil engineers and scientists in the field of earthquake engineering and structural dynamics to exchange knowledge, experiences, best practices, innovations and research results.
The Windtechnologische Gesellschaft (WTG) e.V. is holding an event in Aachen on the theoretical and practical modelling of wind effects (https://windfx.net). Wind engineering, like many other technical fields, is entering a new era. Algorithms based on artificial intelligence that can handle particularly large amounts of data and are thus able to identify patterns and features that were previously hidden may play a role in the future. For the first time, a workshop in the field of earthquake engineering was also held at this year's conference. SDA contributed two presentations to the workshop. These dealt with earthquake damage in Turkey and the seismic design of masonry structures.
SDA will lead a webinar for Part 4 of the new generation of Eurocode 8 on June 30, 2023, hosted by the European Association of Earthquake Engineering. Part 4 covers the seismic design of silos, tanks, pipelines, technical installations in facilities as well as towers, masts and chimneys. Eurocode 8 applies to the design and construction of buildings and other civil engineering works in seismic regions. 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.
SDA joined an earthquake mission of an international team consisting of ETH Zürich (Prof. Michalis Vassiliou, Dr. Nikola Blagojevic, Safak Arslantürkoglu), Serbian Association of Earthquake Engineering (Prof. Marko Marinković and Nemanja Krtinić). 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.
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.
On June 28, 2023, 4:30 p.m., SDA will present “Earthquake resistant design of masonry structures according to Eurocode 8” as part of the DAfM-Online After-Work Seminars. The presentation will be given by Prof. Butenweg. The DAfM-Online After-Work Seminars are an attractive option for engineers in practice.
For the new program version MINEA Linear, one-hour webinars will be provided in 2023. The contents and dates can be found on the website of MINEA. The webinars are freely accessible and serve to demonstrate the handling of the software with practical examples.
SDA is an industrial partner in the CIRC-Boost project funded by the European Union. The overall objective of the Circ-Boost project is to enable and demonstrate an increase in the large-scale uptake of integrated circular solutions (ICS) in European construction value chains demonstrated through five large scale pilots. These projects are: Development and deployment of novel BIM-based selective demolition and decontamination techniques in Barcelona, structuring the reuse and recycling sector around a physical and digital hub centralizing the flow of materials and waste in the Ile-de-France region, demonstration of the integration of multiple innovative processes and techniques to build a pilot house with recycled and re-usable construction materials in the Balkans region, demonstration of an entire circular process “from demolition to construction” in the Arctic region of Norway and the expansion of the adoption of concrete made with recycled aggregates, to wide industrial implementation across large-scale residential projects. Detailed information about the funding framework are provided on the following website of the EU.
On March 28th and September 26nd 2023 SDA leads seminars on “Seismic Design of Buildings according to DIN EN 1998” organized by the Academy of Engineers West e. V.

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.

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.
