Seismic evaluation of existing reinforced cement concrete building and steel–concrete composite building

In India, concrete is the most ideal material for construction in medium- and low-rise structures, and in high-rise structures, steel is used. Steel-concrete-composite construction is not as popular, but it is possible that steel-concrete-composite construction can be more beneficial in medium- and high-rise structures. Steel-concrete-composite construction can be built instead of reinforced cement concrete (RCC) structures to take advantage of steel and concrete and to produce efficient and economical structures. It is the decision of the client and contractor as to which type of material properties are required in the field, and according to these properties, the type of material can be chosen. In this paper, a comparative study of the dynamic behavior of the RCC and stee-concrete-composite moment-resisting frames is investigated for earthquake loading. Two buildings of G + 15-story situated in earthquake zone III are designed as per IS 800:2007 and IS 1893:2016. The equivalent static method and response spectrum analysis were considered in the ETABS software. A comparison of different four parameters, like displacement, base shear, fundamental time, and storey drift, depicting the response of structures is investigated. The goal of this study article is to compare important indicators such as time and seismic response of steel-concrete composite frames to typical reinforced concrete frames and steel frames for building constructions. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.
