Pushover Analysis of R.C Frames by Considering Bay Width Variation of Structures

Kadlag V.A, Kenkar K.S


Braced Generally analyses of structures are carried out by considering base of the structure as a rigid one or its base condition as a fixed base. But it is observed that due to this assumption of fixity at base condition, the results obtained are very much affected from actual results. From the above, while evaluating seismic structural behavior, the effect of soil structure interaction is of paramount importance. Therefore in this study various structures are analyzed by considering base of the structure as fixed base as well as for various flexible base conditions, which are categorized as medium soil and soft soil. Also the effect of variation in bay width is also taken into account. For analysis purpose in this study structures are considered from G+10 stories to G+20 stories at an interval of 5 stories. While assessing the seismic behavior of structure, the pushover analysis is employed and accordingly its effect in the form of failure hinge formulation is studied.
Keywords— Pushover analysis; Bay width variation; Soil structure interaction; Flexible soil; Hinge failure; Non-linear static method.
