Abstract

Infill walls are non-structural elements, which are mainly used for architectural purposes. Besides contribution of infill walls is ignored during the structural analysis, the effect of the infill walls are usually taken into account through the application of additional loads and masses appropriately distributed along the interfaces between the surrounding frame and the infill walls. In doing so, the stiffness and strength contribution of the latter elements as well as their interaction with the members of the Reinforced Concrete (RC) frame are also ignored. Practically some of the earthquake design codes like Turkish code neglect the effects of the non-structural infill walls. However the presence of infill walls significantly increases the stiffness and the strength of a frame. The reasons of this increment are high in-plane stiffness of infill and the composite action of the infill and the frame. On the other hand, plastering significantly affects the behaviour of infill walls. Thus, the dynamic characteristics of a building also affected by the mu 11 walls of building having plaster or not.
