ANALYSIS OF INFILL WALL BUILDING DESIGN USING RESPONSE SPECTRUM METHOD IN ETABS

RC moment resisting frame buildings are the most preferred type of construction in developing countries like India; due to its relatively low cost, fast and rapid progressive construction. Other important factors like its aesthetic appearance and good functional behavior under earthquake loading makes it the ultimate choice. In addition to above, brick masonry has good characteristics like thermal and acoustic insulation and fire resistance. RC moment resisting frame buildings consist of moment resisting frame with masonry wall as Infills. These walls are considered as non structural elements in construction practices. In present day practice of building design, buildings are designed as framed structures while effect of infill masonry walls is ignored and considered as non structural elements. Due to the above reason, buildings behave in different manner with infill wall when compared with only moment resisting frames. In past four decades, through lots of analytical and experimental studies importance of brick infill has been recognized however its strength and stiffness contribution has been neglected by considering it as non structural elements. Seismic analysis is a subset of structural analysis and is the calculation of the response of the building structure to earthquake and is a relevant part of structural design where earthquakes are prevalent. The seismic analysis of a structure involves evaluation of the earthquake forces acting at various level of the structure during an earthquake and the effect of such forces on the behaviour of the overall structure. The analysis may be static or dynamic in approach as per the code provisions.
