Parametric Analysis of Flat Slab with Shear Wall Lateral Resisting System Subjected to Dynamic Loading

Abstract

Abstract: In the present project 20 storey structure is modelled using ETABS and loadings are considered as per IS codes. The models were analysed for both static and dynamic time history analysis the results are extracted, graphs are plotted. Models were compared and conclusions are drawn. The conclusions drawn from the analysis are, The Static analysis and dynamic analysis are having different values and time history analysis seems to be more accurate due to consideration of modal analysis and sitespecific analysis. The displacement is the main parameter in terms of serviceability criteria, the time history analysis shows lesser values than static analysis. It indicates that the static analysis may be on higher side for high rise structures. The comparatively huge displacement in case of Model M02 for both static and dynamic analysis proves the flat slab structure without drop panel and shear wall is not acceptable for lateral loading. From the overall analysis, it is found that the Column beam system with shear wall is best system to adopt, however in case of project demand, it is better to adopt flat slab drop panel system with shear wall located at centre as preference. In case of difficulty of shear wall at centre, the shear wall at corners can be adopted.
