EFFECT OF HAUNCHED BEAMS IN MOMENT RESISTING RC FRAMES

The need of experimental studies on the motorized behavior of reinforced concrete (RC) Haunched beams leads to difficulties in statistical and reliability analysis. This study performs the analysis of RC framed structure with Haunched beams. Structures composed of Haunched beams, have been recently adopted for many high-rise buildings. STAAD pro has been used for the analysis of RC framed structure with Haunched beams. This paper is concerned with the effects of stiffness attained by considering Haunched beams on the seismic response of a structure and the main objective is to carry out the linear static (seismic coefficient) and linear dynamic (response spectrum) analysis on RC building frames modelled with and without Haunched beams for ten storeys at all seismic zones in India considering IS 1893 (Part 1): 2002 and compare the results of analysis (lateral displacements and natural period). From the results analysis, it was observed that there is an increase in the stiffness of RC frame with Haunched beams than that of the RC frame without Haunched beams.
