STUDY OF BEHAVIOUR OF TUBULAR TALL BUILDING ( SUBJECTED TO WIND AND EARTHQUAKE FORCES )

Abstract

In this project, Analysis of Tubular tall building has been done using STAAD PRO. It has been presumes that, the only periphery Beams/Columns essentially take part in resisting lateral forces and the interior beams and columns transfer gravity load to foundation. This assumption work fairly well in resisting static wind forces and gravity load. When the outer tube is subjected to lateral wind forces the flange and web frames columns experience the positive shear lag phenomenon also. In the first phase pf the research effort, we tried to study the maximum deflection, of the tube without and with shear wall; staggerres shear panels and other patterns of shear panels. It has been observed that if staggered shear panels are used up to 1/3rd height of the tube, they control maximum deflection at top more then that is done by the shear walls provided up to full height. In the second phase of analysis the tubular tall building has been analyses for dynamic forces using STAAD PRO...
