Comparative Study on Unsymmetrical G+15, G+20, G+25 Story Building with Flat Slab, Conventional Slab, And Flat Slab Without Drop
Abstract: There are different types of slabs from which the slab supported by column and beam is called as Conventional slab and the slab which is supported by Column and drop but the beam is not used in this slab is called as flat slab. Live and dead loads are transferred from slab to drop and then it is transfer to columns. This type of slab mostly preferred for long span …

INCREMENTAL DYNAMIC ANALYSIS, EIGEN VALUE ANALYSIS & RESPONSE SPECTRUM ANALYSIS OF EXISTING RC FRAMED BUILDINGS BY USING SEISMOSTRUCT SOFTWARE
Abstract: ABSTRACTCivil Engineering structures are designed to withstand environmental forces like earthquake, along with gravity loads. These forces are random and dynamic in nature. Therefore the response of the structure is also dynamic and that is what causes the unsafe and uncomfortable conditions.So, performance based analysis of the structure is required which can be achieved by Incremental Dynamic Analysis (IDA) as well as Response Spectrum analysis (RSA). But, Incremental dynamic analysis …
