COMPARISON OF FORCE BASED DESIGN AND DIRECT DISPLACEMENT BASED DESIGN OF TWO DIMENSIONAL REINFORCED CONCRETE FRAMES WITH VERTICAL GEOMETRIC AND MASS IRREGULARITIES

Abstract

Buildings with irregularities are unavoidable in the current scenario and these irregularities cause serious damage to the structure during earthquake. The analysis and design of buildings with these irregularities is time consuming. The present study aims to compare the performance of Force Based Design (FBD) and Displacement Design Based Design (DDBD) for buildings with Vertical geometric irregularity and Mass irregularity of two dimensional reinforced concrete frames of four, eight and twelve stories. The performance of these two design procedures were compared using the structural parameters like Interstorey drift and Ductility demand. The results were in favour of DDBD as it helps in achieving better performance.
