Abstract
Over the past decade, several studies investigated behavior aspects of irregular structures and limitations of seismic code provisions for such class of buildings. This paper investigates the dynamic and seismic behavior of buildings employing thick transfer slab between two different structural systems, representing podium and upper tower. The shape of these structures is commonly dictated by either aesthetic or functional considerations that often preclude simplicity or regularity. The purpose of this paper is to assess the seismic damage potential of such structures compared to regular buildings. The seismic behavior is examined under the effects of 6 natural ground motions. The structural damage assessment is conducted through examining drift ratios and damage indices of the overall structure as well as of the significant structural components of RC building. Other significant seismic design parameters such as base and story shear are also assessed for the varying ground motion characteristics. The evaluation and the comparison of the seismic behavior of these buildings, has great impact in attenuating the seismic structural response under various earthquake ground motions. Nonlinear dynamic analyses are performed on a 2-dimensional model of R.C. building.
