摘要：Brick masonry walls are used as infills in reinforced concrete frames (RC). The masonry infill walls aretreated as a non-structural element and are usually neglected in structural analysis and seismic design calculations. Themass of the infill walls is considered while performing analysis, however, its structural properties like strength andstiffness is generally ignored. The structures located in seismic prone areas are more vulnerable to damages as theyhave to resist the lateral force/seismic forces in addition to gravity .The past experience of several researchers hasshown that the brick masonry infill significantly contributed to the seismic performance of the building. However forthe sake of convenience, most of the time, brick masonry infills are treated as non structural members. Therefore, thisconsideration may result in an inaccurate prediction of the strength, lateral stiffness and ductility of RC framedbuildings. Therefore the present investigation was considered to study the effect of brick masonry infill wall on theperformance of the framed structure. For this purpose in present study a building of G+5 storey is considered foranalysis, building is located in seismic zone IV resting on medium soil. In totality five number of models were analysedwhich include Bare frame, complete infill frame and open ground soft storey theses models were analysed usingsoftware ETABS 2015. The infill walls are modelled with 0% and 10% opening at the centre of the wall. The buildingis analysed with both static (Equivalent static lateral force method) and dynamic (Response spectrum analysis) method.Different parameters for the building such as displacement, storey drift, lateral forces on floors and storey drift arestudied and comparisons are made for both ESLM (Equivalent Static Lateral force Method) and RSA (Responsespectrum analysis). As the area of opening increases the strength and stiffness of RC infilled frame decreases. It wasobserved that performance of infill frames is better than those of bare frames when subjected to seismic forces. Oncomparison between ESLM and RSA, the Response spectrum analysis shows lesser values of displacement and driftthan those obtained from Equivalent static lateral force method (ESLM).
