Abstract:

 Seismic analysis will ascertain the conduct of RCC structures during seism. The seismic evaluation greatly hinge on materials, ductility of structural members, strength, stiffness and reinforcement detailing. Criteria for Earthquake Resistant Design of Structures (IS 1893:2002) have provisions to follow different framing systems. In this study ordinary moment resisting frames (OMRF) and special moment resisting frames (SMRF) are used as framing systems. A G+5 mini civil station building at Calicut is selected for the study. For the purpose of equivalence the G+5 building is modified to a G+10 building with all floors typical. The two buildings are rendered with SMRF and OMRF framing systems and analysed in four different seismic zones. The modeling of the structure is done in Extended Three Dimensional Analysis of Building System (ETABS) software. Thus sixteen models with SMRF and OMRF framing system in all seismic zones are generated and comparisons are made on analytical results such as maximum shear force, maximum bending moment and maximum story drift. This project will help in determining best framing system in high rise building in defying the earthquake encroachment.
