Analysis of Masonry Infilled Frame with &without Different Percentage of Opening

Abstract

In the analysis and design of building frames it is commonly assumed that the masonry infill which acts as a non structural elements do not contribute to their strength and stiffness. But as a matter of fact, behavior of the structure is affected by non structural elements in earthquake loads, thus a mathematical model is required to design structures. The deficiencies in current approach of modeling are more pronounced during dynamic response such as in the event of earthquake. Thus contribution of non structural elements needs to be accounted for realistic ally. The scope of the present study is limited to masonry in filled RC frames with and without opening. In this paper collage building (g+3) and (g+5) located in seismic zone III is considered by modeling of frame and infill. The infill panels are modeled as a diagonal struts and surrounding frames as a frame elements. Static analysis is carried out on the models such as bare frame, strut frame, strut frame with centre and corner opening and are performed by software Staad -Pro from which different parameters are computed.
