ANALYSIS TO STRENGTHEN SOFT STOREY RC BUILDING VIA HORIZONTAL EQUIVALENT DIAGONAL STRUTS

With the advancement in field of high rise construction, various types of frame arrangements have been emerged. Le Corbuiser popularly known as LC was one of the pioneers of, what is now called five points of modern architecture. Hence, he deviced the concept of soft storey, in which stiffness is altered, along with storey height to achieve an asthetic view. The present study is an attempt to analyse soft storeys strengthened using vertical pattern of equivalent diagonal struts. The equivalent diagonal struts method was proposed by Stafford Smith and Hendry, in which the concept of equivalent width was formulated mathematically. The total cases studied are 14 (7 with struts and 7 without struts). Seismic zone II is considered in the analysis. Results are analysed in terms of bending moments, shear forces, nodal displacements and storey displacements. Graphical outputs are also generated
