Studies on effect of lateral force on different types of composite building frame systems

Abstract

Behavior of tall building depends on the performance of composite materials used for construction. Strength, stiffness and durability are the key factors to be ensured in the structural elements of the building. Building frame systems with RCC, frame systems with steel and frame systems with composite members are normally used for the construction of tall buildings. Lateral strength and stability of buildings with composite members were found to perform better under static and dynamic loads. Effect of different column profiles (steel column, composite column with square section, and composite column with circular section) on strength and deformation behavior of framing systems are investigated in this paper. A six storeyed framing system with height of 18m is considered for the investigation. It is found that composite column with circular section performs better in terms of strength and stiffness. Also comparison has been made among the three types of column to check the axial load resistance and lateral deformation.
