Abstract

Today in the world of concrete we are rapidly constructing multi-storey building for commercial and residential purposes, but providing a proper parking space is major concern especially in metropolitan cities. Hence the trend has been utilize the basement of building for parking purpose for this engineer provides the solution they make the basement of the building open, no infill masonry walls is provided in the basement .they did not consider the stiffness and strength of the masonry wall .But this conservative design is not always right .We see when the earthquake occur the column of the ground storey collapse down and the upper storey inclined towards the ground because the upper stories are more stiffer than the lower storey. This failure is termed as soft storey effect because ground storey is more flexible in comparison of upper stories. Open ground storey is also known as weak stories because it is also weaker in strength in comparison of upper stories .After the Bujh Earthquake in Gujarat, India the failure of upper stories emphasis to consider the strength and stiffness of the infill masonry .Therefore IS Code 1893:2002 suggests that we need not to consider the strength of infill masonry but simply consider a factor 2.5 which is known as the multiplication factor for the neutralization the effect of soft storey. It is in clause 7.10.3 (A) of IS 1893:2002 that the beams and columns of the storey need to be taken 2.5 times more the storey shear and moments calculated under specific loads of the bare frame. Nonetheless, by the expertise of the structural design the value suggested by IS CODE 1893:2002 is not realistic. For the validation of the multiplication factor we prepare a separate model for infill wall and walls without any infill i.e. bare frame, and do the linear and nonlinear analysis and compare their results. Linear analysis shows stiffness is constant in both open ground storey and bare frame while non-linear shows the multiplication factor can be reduced.

Key Words

G+3 building, Open storey, Linear and non-linear analysis, Pushover Analysis, Multiplication Factor.
