Brittle behaviour of the masonry infills in combination with the ductile behaviour of the RC frames makes infill walls prone to damage during earthquakes. Interstory deformations lead to an interaction between the infill and the RC frame, which affects the structural response. The result of this interaction is significant damage to the infill wall and sometimes to the surrounding structural system too. In most design codes, infill walls are considered as non-structural elements and neglected in the design process, because taking into account the infills and considering the interaction between frame and infill in software packages can be complicated and impractical. A good way to avoid negative aspects arising from this behavior is to ensure no or low-interaction of the frame and infill wall, for instance by decoupling the infill from the frame. This paper presents the numerical study performed to investigate new connection system called INODIS (Innovative Decoupled Infill System) for decoupling infill walls from surrounding frame with the aim to postpone infill activation to high interstory drifts thus reducing infill/frame interaction and minimizing damage to both infills and frames. The experimental results are first used for calibration and validation of the numerical model, which is then employed for investigating the influence of the material parameters as well as infill's and frame's geometry on the in-plane behaviour of the infilled frames with the INODIS system. For all the investigated situations, simulation results show significant improvements in behaviour for decoupled infilled RC frames in comparison to the traditionally infilled frames.}, language = {en} } @inproceedings{GiresiniButenwegAndreinietal.2014, author = {Giresini, Linda and Butenweg, Christoph and Andreini, M. and De Falco, A. and Sassu, M.}, title = {Numerical calibration of a macro-element for vaultes system in historic churches}, series = {9th International Conference on Structural Analyses of Historical Conctruction, 14 - 17 October, 2014, Mexico City}, booktitle = {9th International Conference on Structural Analyses of Historical Conctruction, 14 - 17 October, 2014, Mexico City}, organization = {International Conference on Structural Analyses of Historical Conctructions <9, 2014, Mexico City>}, pages = {1 -- 12}, year = {2014}, language = {en} } @inproceedings{TaddeiReindlParketal.2011, author = {Taddei, Francesca and Reindl, Lukas and Park, Jin and Butenweg, Christoph and Karadogan, Faruk}, title = {Numerical investigation of AAC wall panels based on the damage plasticity constitutive law}, series = {Cement, Wapno, Beton ; 2011, 7, Special issue: 5th International Conference on Autoclaved Aerated Concrete 'Securing a sustainable future' to be held at Bydgoszcz to celebrate 60 years of AAC experience in Poland, Bydgoszcz, September 14-17, 2011}, booktitle = {Cement, Wapno, Beton ; 2011, 7, Special issue: 5th International Conference on Autoclaved Aerated Concrete 'Securing a sustainable future' to be held at Bydgoszcz to celebrate 60 years of AAC experience in Poland, Bydgoszcz, September 14-17, 2011}, publisher = {Stowarzyszenie Producent{\´o}w Cementu i Wapna}, address = {Krakow}, organization = {International Conference on Autoclaved Aerated Concrete 'Securing a sustainable future' <5, 2011, Bydgoszcz>}, issn = {1425-8129}, pages = {86 -- 91}, year = {2011}, language = {en} } @inproceedings{KubalskiMarinkovićButenweg2016, author = {Kubalski, T. and Marinković, Marko and Butenweg, Christoph}, title = {Numerical investigation of masonry infilled R.C. frames}, series = {Brick and Block Masonry.

Although infills are considered as non-structural elements, they significantly change dynamic characteristics of RC frame structures during earthquake excitation. Recently, significant effort was spent on studying decoupled infills, which are isolated from the surrounding frame usually by adding a gap between frame and infill. In this case, the frame deformation does not activate infill wall, thus infills are not influencing the behaviour of the frame. This paper presents the results of the investigation of the behaviour of RC frame buildings with the INODIS system that decouples masonry infills from the surrounding frame. Effect of masonry infill decoupling was investigated first on the one-bay onestorey frame. This was used as a base for parametric study on the frames with more bays and storeys, as well as on the building level. Change of stiffness and dynamic characteristics was analysed as well as response under earthquake loading. Comparison with the bare frame and traditionally infilled frame was performed. The results show that behaviour of the decoupled infilled frames is similar to the bare frame, whereas behaviour of frames with traditional infills is significantly different and demands complex numerical models. This means that if adequate decoupling is applied, design of}, language = {mul} } @article{RossiHoltschoppenButenweg2019, author = {Rossi, Leonardo and Holtschoppen, Britta and Butenweg, Christoph}, title = {Official data on the economic consequences of the 2012 Emilia-Romagna earthquake: a first analysis of database SFINGE}, series = {Bulletin of Earthquake Engineering}, volume = {17}, journal = {Bulletin of Earthquake Engineering}, number = {9}, publisher = {Springer}, address = {Berlin}, doi = {10.1007\%2Fs10518-019-00655-8}, pages = {4855 -- 4884}, year = {2019}, language = {en} } @inproceedings{ButenwegThierauf1997, author = {Butenweg, Christoph and Thierauf, Georg}, title = {Optimum cost design of reinforced concrete structures using parallel computing}, series = {Advances in computational mechanics with parallel and distributed processing : research papers presented at The First Euro-Conference on Parallel and Distributed Computing for Computational Mechanics, held at Lochinver, Scotland, between 26 April and 1 May 1997 / ed. by B.

Many studies confirmed that infill walls interact with the surrounding reinforced concrete frame, thus changing dynamic characteristics of the structure. Consequently, masonry infills cannot be neglected in the design process. However, although the relevant standards contain requirements for infill walls, they do not describe how these requirements are to be met concretely. This leads in practice to the fact that the infill walls are neither dimensioned nor constructed correctly. The evidence of this fact is confirmed by the recent earthquakes, which have led to enormous damages, sometimes followed by the total collapse of buildings and loss of human lives. Recently, the increasing effort has been dedicated to the approach of decoupling of masonry infills from the frame elements by introducing the gap in between. This helps in removing the interaction between infills and frame, but raises the question of out-of-plane stability of the panel. This paper presents the results of the experimental campaign showing the out-of-plane behavior of masonry infills decoupled with the system called INODIS (Innovative decoupled infill system), developed within the European project INSYSME (Innovative Systems for Earthquake Resistant Masonry Enclosures in Reinforced Concrete Buildings). Full scale specimens were subjected to the different loading conditions and combinations of in-plane and out-of-plane loading. Out-of-plane capacity of the masonry infills with the INODIS system is compared with traditionally constructed infills, showing that INODIS system provides reliable out-of-plane connection under various loading conditions. In contrast, traditional infills performed very poor in the case of combined and simultaneously applied in-plane and out-of-plane loading, experiencing brittle behavior under small in-plane drifts followed by high out-of-plane displacements. Decoupled infills with the INODIS system have remained stable under out-of-plane loads, even after reaching high in-plane drifts and being damaged.}, language = {en} } @article{TaddeiButenwegKlinkel2015, author = {Taddei, Francesca and Butenweg, Christoph and Klinkel, S.}, title = {Parametric investigation of the soil-structure interaction effects on the dynamic behaviour of a shallow foundation supported wind turbine considering a layered soil}, series = {Wind energy : an international journal for progress and applications in wind power conversion technology}, volume = {Volume 18}, journal = {Wind energy : an international journal for progress and applications in wind power conversion technology}, number = {Issue 3}, publisher = {Wiley}, address = {Weinheim}, issn = {1099-1824 (E-Journal); 1095-4244 (Print)}, doi = {10.1002/we.1703}, pages = {399 -- 417}, year = {2015}, language = {en} } @incollection{Butenweg2017, author = {Butenweg, Christoph}, title = {Passt, wackelt und hat Luft: Mauerwerksbauten aus Leichtbeton in Erdbebengebieten}, series = {Beton-Bauteile, 65.

It turns out that different foundations on varying soil configurations heavily influence the vibration response.

An overview of policy measures for the seismic and energy upgrading of buildings across EU Member States identified only a few available measures for combined upgrading. Regulatory framework, financial instruments and digital tools similar to those for energy renovation, together with awareness and training may promote integrated renovation. A framework for regional prioritisation of building renovation was put forward, considering seismic risk, energy efficiency, and socioeconomic vulnerability independently and in an integrated way. Results indicate that prioritisation of building renovation is a multidimensional problem. Depending on priorities, different integrated indicators should be used to inform policies and accomplish the highest relative or most spread impact across different sectors. The framework was further extended to assess the impact of renovation scenarios across the EU with a focus on priority regions. Integrated renovation can provide a risk-proofed, sustainable, and inclusive built environment, presenting an economic benefit in the order of magnitude of the highest benefit among the separate interventions.
