The Effect of Openings on Out-of-Plane Capacity of Masonry Infilled Reinforced Concrete Frames

Reinforced concrete frames are usually infilled with masonry walls. However, during the seismic design of RC buildings, the contribution of masonry walls in the overall seismic performance of the frame is mistakenly neglected. This paper, discusses the effect of openings on out-of-plane behavior of masonry infilled reinforced concrete frames. A series of numerical analyses were conducted on a 1/2.5 scale model structure of single-bay single-storey infilled frame containing a door or medium sized window openings, centrically and eccentrically positioned. Use made of the three-dimensional software ATENA 3D Eng. The numerical model was initially calibrated against experimental tests. Then, a monotonic out-of-plane uniform load was applied in the structure and the failure mechanisms and force against displacement relationships obtained. From the results analysis, it was found that the presence and type of openings significantly influence the out of plane behavior of RC frames with openings.
