The stiffness of masonry infill walls is commonly neglected in design practice of Reinforced Concrete (RC) structures. In fact, the stiffness of masonry infill wall may significantly influence seismic performance and dynamic behavior of RC buildings. In this research, influence of masonry infill walls to the structural performance of a three-story RC frame is investigated. In addition, possible application of friction-based support is also studied. Full 3D non-linear time history analysis is conducted to observe behavior of the structure under two-directional ground motion. In the analysis, any failed elements are removed subsequently from the model to avoid numerical analysis problem. The result shows that the placement of masonry infill walls can significantly influence the structural behavior of RC structure. Inappropriate placement of masonry wall may lead the building undergo soft-story mechanism. It is also found that the use of friction-based support can effectively improve the seismic performance of the building.

“…As was shown by Manos and co-workers (Manos [3], Gulkan [4][5]) for low-rise well-built masonry structures, the inplane behavior can be studied separately from the out-of-plane behavior. When subjecting such masonry walls simultaneously to combined in-plane horizontal and vertical loads (Hidalgo et al [6], Tomazevic et al [7]), the most significant parameters that are usually examined are the type and strength of the mortar and masonry units, the geometry of the masonry walls and their reinforcing arrangement (in quantity and structural details), and the level of axial compression (Tasios [8]). Oan Shrive [9] examined the shear behavior of concrete masonry walls whereas Sandoval, C. et al [10] investigated the in-plane cyclic response of partially grouted reinforced clay brick masonry walls in a way similar to the one employed in the present work.…”

The main features of a study dealing with partially grouted reinforced clay brick masonry wall specimens are summarized here. Results from an experimental campaign studying the inplane behavior of such partially grouted wall specimens, built using novel clay bricks with vertical holes manufactured in Greece, are presented and discussed. All wall specimens were partially grouted at specific locations hosting vertical steel reinforcement. Horizontal (shear) steel reinforcement was also included at the mortar bed joints. These specimens were rigidly attached at a reaction frame and were subjected at their top to a constant vertical load together with a horizontal seismic-type in-plane cyclic load. A key issue in the construction of these wall specimens is the masonry unit which is employed. Due to the thermal insulation requirements as well as the revisions in the provisions of the Euro-Code relevant to the seismic design and construction of unreinforced and reinforced masonry, a novel masonry unit was designed and tested. The design was based on preliminary material tests and a series of numerical simulations. The thermal insulation properties of this new unit were also taken into account in its design as well as the accommodation of the transverse horizontal joint reinforcement that was to be accommodated in a thin layer mortar joint. Summary results of all these aspects in the design and construction of this new masonry unit are present and discussed.
