“…Moghadam [9] conducted an intensive research on the seismic behavior of infilled frames and the research results included many aspects, such as the crack strength determination of infilled steel frames (Moghadam et al [10]), the impact of repair and retrofit on in-plane behavior of masonry infilled steel frames (Moghadam [11]), seismic strengthening of masonry infilled structures (Moghadam and Mahmoodi [12]), mathematical functions to evaluate stress of infilled frames (Mahmoodi and Moghadam [13]), discrete element method in the nonlinear analysis of masonry-infilled steel frames with opening (Mohammadi et al [14]). …”

Cyclic loading tests on eight full-scale one storey, one-bay test specimens were carried out to study the hysteretic behavior of steel frames infilled with sandwich composite panels. Six main influential parameters, including panel thickness, panel type, panel position, column orientation, beam-to-column connection type and connecting method of panel to steel frame are considered. Based on the experimental phenomena, seismic behaviors of specimens were reflected by hysterics loops, skeleton curves, curves of strength degradation, curves of stiffness degradation, ductility coefficient and equivalent damping coefficient. Test results show that the failure modes of panels and steel frames are concrete spalling around the embedded parts, weld fracture, and local buckling of beam, respectively. The integrity of the panel is better than the traditional walls. The success of connection between panel and steel frame is significant to the mutual work of the two parts. Both of increasing the panel thickness and strengthening the connection can improve the seismic behavior of structure. At the end of the paper, seismic design recommendations based on the analysis of ductility index and energy dissipation of the structures are presented.

“…Those studies that were carried out are mainly restricted to masonry infills. It has been demonstrated that the presence of an opening in the infill substantially alters the performance of infilled frames [3][4][5]. Furthermore, recommendations have been made for suitable opening positions within an infill [6].…”

“…However, many researchers found that the single compressive strut model could not reproduce the flexural moments and shear forces created in the frame members and showed that diagonal strut models did not accurately address all aspects of the interaction between the frame and the infill; ( [Reflak et al 1991], [Buonopane et al 1999], [Chaker et al 1999], [Mohebkhah et al 2007] and [Asteris et al 2011] among many others). In addition, there were still disagreements about the width of equivalent strut considered in the modeling process.…”

“…A number of researchers applied the strut model to perforated infill walls and found that the lateral resistance, initial stiffness and energy dissipation capacity of perforated infill walls could be significantly lower than solid infill walls ( [Benjamin et al 1958], [Mallick et al 1971], [Liauw et al 1977], [Utku 1980], [Giannakas et al 1987], [AlChaar et al 2003], [Asteris 2003], [Mohebkhah et al 2007] and [Mondal et al 2008]). …”

“…one diagonal and two off-diagonal struts in order to describe the orthotropic behavior of the masonry. This model was later adopted by [Mohebkhah et al 2007] to consider the nonlinear global behavior of infilled steel frames with central openings. In his Ph.D. thesis, Crisafulli showed that even the most complicated multiple-strut model, such as that proposed by Thiruvengadam [1985] was not capable of describing the response of the infilled frame systems when horizontal shear sliding occurs in the masonry panel [Crisafulli 1997].…”

In this dissertation the performance of masonry walls enclosed by frame structures is studied and a new finite element model for these systems is presented. As part of this effort, the common modeling approaches i.e. micro-models and macro-models are briefly reviewed and their specifications are compared. Based on the findings in these comparisons, it was shown that macro modeling is the preferred modeling approach and the development of the new model is presented. The proposed model is described in detail and the calibration procedures along with the material models, used in the proposed model, are presented. To account for the interaction of the frame and the shear wall a contact member is developed. In support of this development three of most common solutions for contact problems that can be also used in modeling the frame-infill interaction problem are described; a detailed description for the chosen method along with a simple structural example is given. vii
