Deflection Control of High Rise Symmetrical Building Using Bird Cage Interlocking Frame

摘要

Earthquakes are among the most deadly natural hazards. When large earthquakes occur in such areas the results can be catastrophic, with terrible loss of human lives and untold economic cost. To overcome due to seismic and wind loads, providing birdcage like structure around the building which consists of steel sections. It protects the building by providing cage around the structure at elevation which prevents the structure from deflection or displacement of building due to wind and seismic loads. The nature of the soil is another factor which determines the extent of damage. A 22 storied building analyzing and designing with different wind speeds & earthquakes comparing with different soils(I,II,III) and earthquake zones(Z-2,Z-3,Z-4,Z-5). An Educational package ETABS has been utilized for analyzing high-rise building of 66.5m height and for different zones The results of the analysis on the Shear force, Bending moment and Torsion are compared. The results are presented in tabular and graphical form. The results on the displacement are checked with serviceability conditions and are compared and presented in tabular form. Concluding remark has been made on the basis of this analysis & comparison table.
