An Interpretation of Seismic Behavior of Tube in Tube Building and Moment Resisting Building

Abstract

Lately, Tubular structures have been broadly utilized as structural key for tall structures in the field of structural engineering. Tubular structure of different types, are generally utilized because of their high solidness in opposing lateral loads, increase in the utilization of floor spacing and more economic in construction. The parametric analysis was completed on two 40-storey RCC buildings using the software ETABS. Here in this paper, the performance of Tube in Tube building and a moment resisting frame building will be investigated. The models are studied employing continuum approach in which the continual connecting means i.e. beams connecting vertical members and horizontal slabs are assumed to have equitably dispersed stiffness properties. Equivalent static method and Response spectrum method is applied and the analysis results of moment resisting frame and tube in tube buildings are studied to have a comparative analysis of their seismic performance.
