“…The results show that it is very important to account for such eventual gap because the overall behaviour of the frame is significantly affected. The behaviour of the structure corresponds to that observed in experimental testing [29]. While there is no contact between the frame and the infill, the structure behaves exactly as the bare frame.…”

Partition walls are often made of masonry in Romania. Although they are usually considered non-structural elements in the case of reinforced concrete framed structures, the infill panels contribute significantly to the seismic behaviour of the building. Their impact is difficult to assess, mainly because the interaction between the bounding frame and the infill is an intricate issue. This paper analyses the structural behaviour of a masonry infilled reinforced concrete frame system subjected to in -plane loading. Three numerical models are proposed and their results are compared in terms of stiffness and strength of the structure. The role of the openings in the infill panel on the behaviour is analysed and discussed. The effect of gaps between the frame and the infill on the structural behaviour is also investigated. Comparisons are made with the in-force Romanian and European regulations provisions.

“…The finite element model for this new system has been developed using the DIANA program. [8] Lavanya, N. Murali Krishna et.al. (2015) in their paper discussed that the contribution offered from infill walls to the lateral strength of the building is evaluated using a combination of FEM approach and Neural Networks.…”

Natural Calamities such as Earthquakes and cyclones cause lateral forces in buildings. Tall Buildings are highly vulnerable to these lateral forces. Designing such buildings to withstand the lateral forces which occur occasionally is considered very expensive. The lateral strength contributed by the infill wall elements is considered to be substantial. Many researchers have adopted different methods to evaluate the lateral strength contributed by wall panels, as on today no complete method has been evolved successfully. In the present work, the lateral strength contributed by the infill panels is explored making use of Finite Element concept. The general purpose of Finite Element package by name MSC NASTRAN is used for the needful calculations. Essentially the Strain Energy contributed by the infill panel in the composite frame structure is equated to the strain energy contributed by an equivalent diagonal strut replacing the infill panel together with bounding frame. Width of such strut is evaluated analytically using MSC NASTRAN. The calculations for strain energy with equivalent diagonal struts is taken-up using STAAD Pro for comparison.

“…Masonry is a combination of brick and mortar; the failure mechanism of masonry depends mainly on the behavior and interaction between each composition. The complex mechanical properties of masonry result from the following [ 6 , 7 , 8 ]: (1) brick and mortar are nonlinear materials with significant discrete characteristics; and (2) the tension and shear capability of mortar are much lower than brick, making mortar the weak link in the whole structure. Hence, the brick joints determine the entire mechanical characteristics of masonry.…”

The behavior of dry stack masonry (DSM) is influenced by the interaction of the infill with the frame (especially the joints between bricks), which requires further research. This study investigates the compression and shear behaviors of DSM. First, a series of compression tests were carried out on both masonry prism with mortar (MP_m) and DSM prism (MP_ds). The failure mode of each prism was determined. Different from the MP_m, the stress-strain relationship of the MP_ds was characterized by an upward concavity at the initial stage. The compression strength of the MP_ds was slightly reduced by 15%, while the elastic modulus was reduced by over 62%. In addition, 36 shear-compression tests were carried out under cyclic loads to emphasize the influence of various loads on the shear-compression behavior of DSM. The results showed that the Mohr-Coulomb friction law adequately represents the failure of dry joints at moderate stress levels, and the varying friction coefficients under different load amplitudes cannot be neglected. The experimental setup and results are valuable for further research.
