Comparative Study of Seismic Responses of RCC, Steel and Mix Construction

Structural engineers are facing the challenge of striving for the most efficient and economical design solution while ensuring that the final design of a building must be serviceable for its intended function, habitable for its occupants and safe over its design life-time. A Building of mixed Construction , in which the Structure is partly concrete and partly Structural Steel have been built for many years in many parts of the world. In general, this type of construction consists of either steel frames with concrete encasement or structure in which shear wall, tube frame, or other major components are concrete while the remainder of the framing is steel. A New form of mix construction in which five stories steel structure is stacked on top of a five story concrete structure. A RCC medium rise building of 10 stories with floor height 3.5m subjected to earthquake loading in V Zone has been considered. The variation of seismic response of mix construction building depending on various analysis methods namely Equivalent static method, Response spectra method and Time history method are evaluated and compared. This study examines G+10 stories buildings of R.C.C., Steel, & Mix Construction are analyzed and design under effect of wind and earthquake using ETABS. All three models are analyzed & designed by response spectra analysis & it proves that Mix Construction Frame building is satisfied the all result. Analytical results are compared to achieve the most suitable resisting system & economic structure against the lateral forces.
