Study of Seismic Behavior of Building with Different Positions and Types of Floating Column

The columns which are supported on a beam instead of rigid foundation are called as floating columns. In many cases floating column adopted to fulfill room sizes criteria of architects. Many buildings in India are constructed with floating column. The lateral forces such as earthquake and wind forces are majorly effect on this kind of structure. Structure with floating column must be sound enough to resist such lateral forces. Structure shall sustain earthquake and wind load and shall pass in all load combination of IS456 and IS 1893-2002. There are numerous observations of damages caused by irregularity in buildings, such as vertical irregularity, is predominant to structure while earthquake excitation, the earthquake forces developed at different floor levels in building need to be brought down along the height to the ground by the shortest path, any deviation or discontinuity such as floating columns results in poor performance of building. The aim of thesis work is to compare the response of RC frame buildings with different types of floating columns under earthquake loading. The effect of earthquake forces on various building models for various parameters is proposed to be carried out with the help of RSA (Response Spectrum Analysis). This work includes analysis of structure by using ETABS software (Extended Three Dimensional Analysis of Building Systems).
