Torsional Behavior of Irregular RC Building under Static and Dynamic Loading

Abstract:

In the present situation the growth of population is increasing rapidly. In view of this, the development of the buildings are changing its dimension to high rise structures further having trends of structural irregularities. These kinds of irregularities in the structure cannot be avoided as it is more vulnerable to the seismic actions. The structure fails by the uneven moments created by the seismic actions because of the irregularities in the structure which is based on the parameters like storey drift, displacement, torsional effects etc., In this paper the effects of the torsional irregularity is studied and the failure has been minimized by adding necessary elements like shear wall and bracings where ever required. In Present study we have considered the 20 storey building of reinforced concrete structure which includes five models of different regular and irregular shaped structures which are subjected to earthquake load and are modeled by using ETABS version 9. Analysis results elaborate the parameters like displacement, time period, storey drift and comparisons of the results among the set of models.
