RESPONSE OF R.C. BUILDING WITH SHEARWALLS AND DIFFERENT SYSTEMS OF BRACINGS

Abstract

Shear wall has high in-plane stiffness and strength which can be used simultaneously resist lateral loads
and gravity loads. Bracing is a highly efficient and economical method of resisting lateral forces in a frame structure
because the diagonals work in axial stress and therefore call for minimum member sizes in providing the stiffness and
strength against horizontal shear. In this paper, Special moments resisting frame(SMRF), SMRF with Shear wall at
corners of building and SMRF with four bracing systems have been investigated for the use in high rise building in order
to provide lateral stiffness and finally comparing the roof displacements, story drifts and cost. For this purpose, 10 and
15 story building is selected for in Earthquake zone III and comparison id done. The analysis and design was done with
the help of ETABs software. It is observed that the shear wall model have many a dvantages over the other two systems
and the cost required is also less.
