Abstract |
In hilly areas most of the engineering structures are constructed by considering local topography that is on sloping grounds results in the using of a step back method or step & set back method. The structures are irregular due to adoption of these methods and it leads to increased shear and torsion during seismic ground motion because of its irregularity in structures and by virtue of different column heights. Using Equivalent static method and Response Spectrum method the analysis is carried out to the step & set back framed building and step back framed buildings on slope grounds with different number of storeys. The lateral displacement, storey drift, time period and base shear induced in column are studied for the different number of storey and building heights. The result shows that the step & set back type of building frames are best suitable for sloping ground or in hilly areas as compared with step back type of building frames. By considering steel bracings to step back types of framed buildings, a better performance can be observed. |
