  abstract  = {Damage of reinforced concrete (RC) frames with masonry infill walls has been observed after many earthquakes. 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.},

  abstract  = {The sandfish (Scincus scincus) is a lizard having the remarkable ability to move through desert sand for significant distances. It is well adapted to living in loose sand by virtue of a combination of morphological and behavioural specializations. We investigated the bodyform of the sandfish using 3D-laserscanning and explored its locomotion in loose desert sand using fast nuclear magnetic resonance (NMR) imaging. The sandfish exhibits an in-plane meandering motion with a frequency of about 3 Hz and an amplitude of about half its body length accompanied by swimming-like (or trotting) movements of its limbs. No torsion of the body was observed, a movement required for a digging-behaviour. Simple calculations based on the Janssen model for granular material related to our findings on bodyform and locomotor behaviour render a local decompaction of the sand surrounding the moving sandfish very likely. Thus the sand locally behaves as a viscous fluid and not as a solid material. In this fluidised sand the sandfish is able to "swim" using its limbs.},

Oktober 2013 ist das auf drei Jahre angelegte EU-Forschungsprojekt INSYSME - Innovative Systeme f{\"u}r erdbebentaugliche Ausfachungsw{\"a}nde aus Ziegelmauerwerk in Stahlbetonrahmentragwerken - gestartet. Unter der Koordination der Universit{\"a}t Padua beteiligen sich 16 Partner aus sechs europ{\"a}ischen L{\"a}ndern (Deutschland, Griechenland, Italien, Portugal, Rum{\"a}nien, T{\"u}rkei). Als deutsche Partner nehmen die Arbeitsgemeinschaft Mauerziegel aus Bonn, die Universit{\"a}t Kassel sowie das Ingenieurb{\"u}ro SDA-engineering GmbH aus Herzogenrath, teil. Ziel der deutschen Partner ist die Entwicklung von innovativen Ausfachungssystemen aus monolithischem w{\"a}rmed{\"a}mmenden Ziegelmauerwerk, mit denen nicht nur eine erh{\"o}hte Erdbebensicherheit, sondern auch die sichere Erf{\"u}llung der steigenden Anforderungen aus Windbeanspruchungen gew{\"a}hrleistet werden k{\"o}nnen. Die Forschungsergebnisse sollen vom Partner SDA-engineering GmbH in die bereits seit einigen Jahren verf{\"u}gbare Softwarel{\"o}sung MINEA [1] integriert werden. Weitere Informationen stehen auf den Websites des Projektes [2] zur Verf{\"u}gung. Im vorliegenden Beitrag werden nach einer kurzen thematischen Einf{\"u}hrung die Ergebnisse von Tastversuchen an senkrecht zur Ebene belasteten Ausfachungsw{\"a}nden aus Planziegelmauerwerk vorgestellt. Im Anschluss wird das geplante Arbeitsprogramm der deutschen Partner im Projekt INSYSME beschrieben.},

  abstract  = {This paper proposes a quick and simplified method to describe masonry vaults in global seismic analyses of buildings. An equivalent macro-element constituted by a set of six trusses, two for each transverse, longitudinal and diagonal direction, is introduced. The equivalent trusses, whose stiffness is calculated by fully modeled vaults of different geometry, mechanical properties and boundary conditions, simulate the vault in both global analysis and local analysis, such as kinematic or rocking approaches. A parametric study was carried out to investigate the influence of geometrical characteristics and mechanical features on the equivalent stiffness values. The method was numerically validated by performing modal and transient analysis on a three naves-church in the elastic range. Vibration modes and displacement time-histories were compared showing satisfying agreement between the complete and the simplified models. This procedure is particularly useful in engineering practice because it allows to assess, in a simplified way, the effectiveness of strengthening interventions for reducing horizontal relative displacements between vault supports.},
