Seismic Performance of Multistorey RC Frame With Various Masonary Infill Bricks

Abstract

Brick is the most commonly used material for building construction. In India it is common use to construct reinforced concrete buildings with unreinforced infill. Infill panels have been made of heavy rigid materials such as red bricks or concrete blocks. Now in India , infill materials such as light weight bricks (AAC) or hollow blocks are to be used as masonry infill material in RC buildings. On the performance of RC buildings, it has been recognized that infill materials have significant effect. This research work on comparison of seismic analysis and design of G+12 building using AAC (Autoclaved aerated concrete block ) and conventional bricks were analysed by under Time history analysis. Infill materials has been accepted influence the seismic performance considerably influence the in filled framed structures. Number of researchers were studied the behaviour of in filled RC frames analytically. Most of the research work carried out , paying attention on parameters such as the variation of distribution of masonry infill and the stiffness of frame elements.. Modelling of the structure is done by Etabs software. Lateral seismic force RC frame is carried out by using equivalent static method as per IS 1893(part 1) : 2002 for earthquake. In the present study is made to study the behavior of RC frame structure using conventional bricks, and light weight bricks (AAC) infill. The various results such as storey acceleration, storey displacement, storey drift, storey stiffness are compared to know the suitable infill material in seismic prone zones.
