Response Spectrum Analysis of Reinforced Concrete Buildings

Response Spectrum Analysis of Reinforced Concrete Buildings In this work, a parametric study on reinforced concrete (RC) structural walls and moment resisting frames building representative of structural types using response spectrum method is carried out. Here, the design spectra recommended by Indian Standard Code [1] and two other well known codes (Uniform Building Code, Euro Code 8) have been considered for comparison. The main objective of this study is to investigate the differences caused by the use of different codes in the dynamic analysis of multistoried RC building. Three different floor plans that are symmetric (SB), monosymmetric (MB), and unsymmetric (UB) with torsional irregularity are taken as sample buildings. To evaluate the seismic response of the buildings, elastic analysis was performed by using response spectrum method using the computer program SAP2000. Periods, base shears, lateral displacement and interstory drift, torque located at code defined ground type are comparatively presented. It is observed from the comparative study that the base shear using IS code is higher in all the three buildings, when compared to that of with other codes. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of The Institution of Engineers (India): Series A Springer Journals

Abstract

In this work, a parametric study on reinforced concrete (RC) structural walls and moment resisting frames building representative of structural types using response spectrum method is carried out. Here, the design spectra recommended by Indian Standard Code [1] and two other well known codes (Uniform Building Code, Euro Code 8) have been considered for comparison. The main objective of this study is to investigate the differences caused by the use of different codes in the dynamic analysis of multistoried RC building. Three different floor plans that are symmetric (SB), monosymmetric (MB), and unsymmetric (UB) with torsional irregularity are taken as sample buildings. To evaluate the seismic response of the buildings, elastic analysis was performed by using response spectrum method using the computer program SAP2000. Periods, base shears, lateral displacement and interstory drift, torque located at code defined ground type are comparatively presented. It is observed from the comparative study that the base shear using IS code is higher in all the three buildings, when compared to that of with other codes.
