Structural And Cost Analysis Of Reinforced Concrete And Steel Framed Structures: A Comparative Study In Lefkoşa, North Cyprus

Abstract

The development of structural systems, materials, and analytical techniques have been used for designing different types of structures. Comparative studies of various buildings help identify the optimum choice depending on the project requirements and conditions. In this study, 8-story residential structures are designed in Lefkoşa, North Cyprus by steel and reinforced concrete frames with different load-resisting systems. Building Code Requirements for Structural Concrete (ACI 318-19) and American Institute of Steel Construction (AISC-15th edition) are both followed and the response spectrum method (RSM) is employed while ETABS and SAP2000 are used for modeling and analyzing the structures. The results obtained are the base shear, story shear, displacement, axial forces, bending moments for selected columns, the quantity of steel, the quantity of concrete, and the quantity of formwork are compared for different structures. The result shows that the cost of steel structure is higher by around 13 % as compared to RC.
