Abstract :
Seismic resistant structures are designed in such a way that they might face partial damage, but will not totally collapse during earthquakes. This design of structures depends on certain parameters like ductility, deformation capacity, strength and amount of deflection. More the ductility, strength and deformation capacity of a structure better will be its seismic resistance, whereas, lesser the amount of deflection, lesser will be the vulnerability of the structure towards earthquakes. This paper deals with the review of various techniques applied in the design of earthquake resistant structural frames without using any external seismic control device. These techniques include the use of smooth rebars and corrosion resistant hybridized columns in construction of Reinforced Concrete (RC) structures, installation of exterior shear walls to the structural frames, construction of brace framed steel structures and construction of composite structures.
