EFFECT OF ORIENTATION OF SHEAR WALLS IN R.C.C. STRUCTURES

Abstract

Major hazards from earthquake, storms, tsunami in recent decades have brought increasing awareness among structural engineers and construction professionals. Earthquakes etc. produce large amount of lateral forces, ordinary frame buildings are not so good to sustain these lateral forces, one has to improve lateral strength of building to resist these lateral forces that comes from these causes. Shear walls in buildings are better solution to counteract these forces. In present work an attempt has been made to study the effectiveness of orientation and thickness of shear walls in resisting lateral forces. It has been found that any location and orientation of shear wall is not effective. For better and economical solution, shear wall should be at appropriate locations. In present work many combination of location and orientation studied. A 10 storey residential building has been chosen for this work that is assumed in earthquake zone 4 in India, wind zone is 4, and soil is soft. Floor...
