Abstract:

Economic viability of RC multistoried building is a key aspect to promote the structures in large scale. In developing countries like India, scarcity of place, and density of population demands vertical development of structural constructions. Geometric configuration of structural elements shows major impact on construction cost of multi storied buildings. In most occasions, building architects influence the configuration of structural elements rather than the decision by structural engineers. This is a big setback for both performance and economy of the structure. There is a need to develop pre-engineered structural models for economic structural configuration of multi storied buildings. Hence this study provides economic viability of multi storied buildings designed under various structural systems. Under the study, six configurated models of RC multistoried building developed based on it’s performance and for a rectangular plot area of different geometrical aspect ratios (1.0, 1.5and 2.0). As per the utility and service requirements, the models are so selected with and without internal columns, based on economic column spacing and large internal column free area. During the design phase, the effect of gravity, wind and seismic loads are taken into consideration. The design models are related to a six storied RC framed structure with rectangular plan area of 20x20m,30x20m and 40x20m (geometric aspect ratio: L/B: 1.0,1.5 and 2.0) located in seismic zone II of Visakhapatnam city, state of Andhra Pradesh, India.
