SEISMIC EVALUATION OF STRENGTHENING OF SOFT STOREY BUILDING CONSIDERING EQUIVALENT DIAGONAL STRUTS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 1
Abstract
The term soft storey explain one level of a building that is significantly more flexible than the stories above it. And to counter the effect of soft storey equivalent diagonal struts are used. The frames with unreinforced masonry can be modelled as equivalent braced frames by replacing infills with equivalent diagonal strut. Equivalent Static method of analysis is a linear static procedure, in which the response of building is assumed as linear static manner. The analysis is carried out as per IS: 1893-2002 (Part 1). In this work G+5 storey (six storey) building is taken in which floor wise (changing soft storey position form first to six storey) soft storey is analysis and its contribution in the behaviour of the structure is examined. Soft storey is more flexible as above storey and we will conclude by getting best geometry in seismic zone; thereby geometry of the building shall be optimized by considering 4 building plan for seismic zones-II. The main objective of this thesis is to investigate the effective building frame with different geometry to withstand under seismic parameters. The investigation is to be carried out by conducting- (a) Modelling of building frames considering different geometries (b) Analysis of frames considering seismic parameters (c) Critical study of results in term of moments, forces and deflections
