Quantity and Cost Modeling of Structural Systems for Reinforced Concrete Buildings (12 To 20 Storeys) Designed for Seismic Effects.


Abstract eng:
Structural systems for reinforced concrete multi-storeyed buildings constitutes one of the major cost component of the total building cost. The structural system costs are influenced by the structural configurations meeting the architectural requirements, structural requirements for providing gravity load and lateral loads resistance for wind and earthquake forces, durability requirements and other factors. Cost predictions for providing required level of seismic resistance in structural components is relatively less understood aspect as very few studies are reported on this matter. There is a need to focus on the issue of cost implications to incorporate seismic safety in buildings. With this objective, the study presents a parametric cost study of the structural systems of medium rise reinforced framed buildings designed and detailed to withstand various levels of code specified seismic forces in different seismic zones of Indian subcontinent. In this study, twelve to twenty storeyed reinforced concrete buildings with moment resisting frames in combination with shear walls with column grids commonly adopted for office occupancy are considered. All these buildings are designed for the design peak ground accelerations of 0.05g to 0.18g applicable for low to high seismic zones as per the Indian seismic code. The proposed quantity model provides for the component wise quantities of structural concrete, steel reinforcement and shuttering materials and the corresponding structural costs per square meter of the built up area of the buildings and thus providing the cost modelling of the structural systems designed for varying levels of seismic effects. The study also presents a compilation of data on the constructed buildings in different seismic zones of India with the quantities of structural concrete and steel reinforcement used per square meter of the built up area of the buildings which broadly compares with the present study. The results of the study, besides bringing out the information on the cost premium to be incurred for seismic safety, provides a simple parametric quantity and cost model for the structural systems of reinforced concrete multi-storeyed buildings designed for different levels of seismic resistance. The study provides an understanding of the economic implications of providing seismic safety in buildings and is useful for the cost management in practice.
