Investigation of Importance of Earthquake Resistant Building with Seismic and Non- Seismic Analysis

Low-rise and medium-rise models shall be prepared, designed and analyzed in the Bentley’s software Staad.pro. Staad.pro is a common designing tool in which the structures are analyzed and designed as per their respective codes. 3 storey, 5 storey, 7 storey and 9 storey buildings were modeled once the modeling is done; different design methods shall be adopted. First, the various structures shall be analyzed without the earthquake forces and then, the same structures shall be analyzed with earthquake forces as per IS: 1893-2016 by considering the various seismic parameters. Design of RCC framed buildings was done as per IS: 456. Grades of steel and concrete were taken as Fe500 and M25 respectively. Rest of the parameters was taken as per the guidelines of aforementioned codes. Result shows that the earthquake resistant buildings entail more material cost (1.16% to 1.35% more than non-seismic resistant building). But the other structural parameters were also increased such as forces and bending moment and displacement as well. The displacement tends to increase 11 times when the earthquake forces were introduced which will not be restrained by the building which was not analyzed with seismic forces. Therefore, it is necessary to analyze the building with earthquake forces so that, in future, the building will be earthquake proof and it can easily withstand its forces. Achieving economy is useless if the building fails during such calamities.
