Comparative and Parametric Study on Codal Provisions of Seismic Analysis of RC Frame Structure as per IS 1893-2016 (Part 1) and IS 1893-2002 (Part 1)

Design of wastewater treatment plant and comparison of efficiency between Mylasandra and V-Valley treatment plants in Bangalore urban District have been analysed for designing of better efficient treatmemt plant. Both the treatment plants have been compared and analysed. The results indicates that V-Valley treatment plant is of greater efficiency than that of the mylasandra treatment plant. Thereby we are of the opinion that the attatched growth process which has been employed in the V-Valley treatment plant is more efficient as of the suspended growth process in Mylasandra after comparing its various parameters such as pH, Bio-chemical Oxygen Demand(BOD), Chemical Oxygen Demand(COD), Total Suspended Solids(TSS) and Dissolved Oxygen(DO). We have designed a more effective and efficient treatment plant with units capable of treating more capacity of wastewater at an even more efficient rate.Considerable improvement in earthquake-resistant design has been observed in the recent past. The sixth revision of IS 1893 (Part 1): 2016, “Criteria for Earthquake Resistant Design of Structures,” have been published by the Bureau of Indian Standards recently in December 2016. The new code comprises changes considering standards and practices prevailing in India. The present work aims at studying the comparison of revisions in various clauses of IS 1893 (Part 1): 2016 with IS 1893 (Part 1): 2002 and their effect on the Equivalent static method and Response spectrum method. The present work focuses on a parametric study of G+3 multistory building with varying the number of storey levels 4, 8, 12, 16 and 20 storeys using ETABS software is performed. The effect of varying storey levels on free vibration and response spectrum analysis is carried out. The different modes of vibrations are observed, and natural frequencies, time periods are tabulated. The RC structure behave in bending for first few modes and later torsion nd then buckling. The first few modes contribute to closely spaced modes with lateral bending, torsion. For increasing number of modes the natural frequencies of the structure increases. The differences in storey displacements, base shear, and storey drift are compared with both codes and the effect of variation is addressed. The base shear increases as a number of strorey increases because of the increase in seismic weight and depends upon the value (horizontal acceleration coefficient).
