Kranzler, Thomas | Shear tests on external clay unit masonry walls / Monolithische Ziegelaußenwände unter Schubbeanspruchung | Mauerwerk | 4/2016 | 259-270 | Fachthemen |
KurzfassungMonolithic external walls are commonly made of thermally insulated clay blocks that do not require any additional external thermal insulation such as an external thermally insulated composite system (ETICS). To reduce thermal bridge losses, the support length (a) of the slab on the wall is shorter than the wall thickness (t): a < t. The influence on the shear capacity of the respective masonry walls has not yet been tested and analysed. The paper presents the results of shear tests on monolithic external walls with a reduced support length under static-cyclic and pseudo-dynamic loading. The test results will be compared with the shear resistance calculated according to DIN EN 1996 with consideration of the German National Annex and the results according to the relevant Technical Approval. x | |||||

Asenov, Milos; Mojsilovic, Nebojsa; Micic, Tatjana | Reliability of masonry walls subjected to in-plane loading: A slip failure along head joints / Zuverlässigkeit von Mauerwerkswänden bei Belastung in der Ebene: Versagen entlang der Stoßfugenflucht | Mauerwerk | 4/2016 | 271-283 | Fachthemen |
KurzfassungMasonry structures are a sustainable, economical and traditionally widely used type of construction. However, current masonry design codes are rather conservative, so there is a growing need for revision i.e. calibration of safety factors to improve the allocation of material resources. In this paper, we investigate the probability of occurrence of slip failure along head joints (perpends) in masonry subjected to in-plane loading. An appropriate limit state function is established and the masonry material properties and loads are defined as random variables in order to simulate likelihood of occurrence of a slip failure regime along the head joints. Furthermore, an example of masonry wall with probabilistic analysis outcomes using Monte Carlo simulation is presented and recommendations for further work are provided. x | |||||
Martens, Dirk R.W. | New approach for spacing of movement joints in reinforced and unreinforced masonry veneer walls. Part 1: Unreinforced masonry / Neue Bemessungsmethode für die Abstände von Dehnungsfugen in bewehrten und unbewehrten Verblendmauerwerksschalen. Teil 1: Unbewehrtes Mauerwerk | Mauerwerk | 4/2016 | 284-294 | Fachthemen |
KurzfassungThe spacing of movement joints has been subject of many discussions. The current methods for the determination of the spacing of movement joints are based on local traditions and bad experience with cracked veneer walls. This has resulted in various design rules throughout Europe with very stringent limits for spacing of movement joints. According to EC6, one of the solutions for increasing the spacing of movement joints is to introduce bed joint reinforcement, although unfortunately no specific design rules are given. Until now, most scientific research has been focused on numerical simulations without taking time-dependent effects into account, which is a conservative approach. In this paper, a new approach is described. It is based on Peter Schubert's model and on practical experience with masonry buildings. x | |||||
Saenger, Dorothea; Brameshuber, Wolfgang | Bond behaviour between textile reinforcement and mortar under tensile loading / Verbundverhalten zwischen textiler Bewehrung und Mörtel unter Zugbeanspruchung | Mauerwerk | 4/2016 | 295-304 | Fachthemen |
KurzfassungExtensive experimental investigations are currently being carried out on various selected materials covering a wide range of properties to achieve a deeper knowledge about the bond performance of textile reinforced mortar (TRM) for masonry strengthening. The objective of the tests includes investigations of the bonding behaviour between alkali-resistant glass textile reinforcement and mortar under tensile loading to determine the required anchorage and overlapping lengths of the reinforcement in the mortar-based material. This article describes the test methods used as well as the results obtained so far. This research will also examine debonding of the mortar-based reinforcement system and the masonry surface under shear load. The definition of these bond parameters is necessary for the design of textile-reinforced masonry components, which will be developed in the near future. The research is also intended to contribute to the finding or even designing of matching alkali-resistant glass textiles specifically for use in masonry. x | |||||
Butenweg, Christoph; Marinkovi , Marko; Kubalski, Thomas; Klinkel, Sven | Masonry infilled reinforced concrete frames under horizontal loading / Stahlbetonrahmen mit Ausfachungen aus Mauerwerk unter horizontalen Belastungen | Mauerwerk | 4/2016 | 305-312 | Fachthemen |
KurzfassungThe behaviour of infilled reinforced concrete frames under horizontal load has been widely investigated, both experimentally and numerically. Since experimental tests represent large investments, numerical simulations offer an efficient approach for a more comprehensive analysis. When RC frames with masonry infill walls are subjected to horizontal loading, their behaviour is highly non-linear after a certain limit, which makes their analysis quite difficult. The non-linear behaviour results from the complex inelastic material properties of the concrete, infill wall and conditions at the wall-frame interface. In order to investigate this non-linear behaviour in detail, a finite element model using a micro modelling approach is developed, which is able to predict the complex non-linear behaviour resulting from the different materials and their interaction. Concrete and bricks are represented by a non-linear material model, while each reinforcement bar is represented as an individual part installed in the concrete part and behaving elasto-plastically. Each brick is modelled individually and connected taking into account the non-linearity of a brick mortar interface. The same approach is followed using two finite element software packages and the results are compared with the experimental results. The numerical models show a good agreement with the experiments in predicting the overall behaviour, but also very good matching for strength capacity and drift. The results emphasize the quality and the valuable contribution of the numerical models for use in parametric studies, which are needed for the derivation of design recommendations for infilled frame structures. x | |||||

Sommerlade, Kai; Seim, Werner | Bracing systems in masonry buildings. Part 1: Simple application of FE programs / Aussteifungssysteme im Mauerwerksbau. Teil 1: Einfache Anwendung von FE-Programmen | Mauerwerk | 4/2016 | 313-320 | Fachthemen |
KurzfassungDue to the low tensile strength of masonry perpendicular to the bed joint, masonry wall panels have non-linear material properties. Assuming simple elastic constitutive laws, this article presents two modelling variants, which consider the lack of tensile strength in a simple manner. Both variants are investigated for their advantages and disadvantages. In a second part of the article, the application of the methods will be illustrated through the example of a four-storey building. x | |||||
