Performance Evaluation of Dual System Structure with Belt Truss

Abstract

In structural engineering applications, boundaries of building deflection or interstory drift are important issues. In tall buildings that are more than or equal to 60 floors in the current era, the Belt Truss System is used in the building structure. The function of the Belt Truss is useful to reduce deflection that occurs in buildings by converting the building’s moment to the axial column of the exterior column. The Structure of the Belt Truss itself can use reinforced concrete structures and steel structures. Because the Belt Truss structure is an innovation in the world of structural engineering, the earthquake load parameter values do not depend on the applicable Building Standart Codes. Standard Codes of Earthquake Resistant Building require parameters of the Response Modification Coefficient (R), Over Strength Factor (fΩo), and Deflection Amplification Factor (Cd) for determining earthquake loads. Because the parameters in the Belt Truss structure are not listed in the Standard Codes of Earthquake Resistant Building, the earthquake load parameters of the Belt Truss were determined. The method used in this research is literature study using Pushover Analysis according to ATC-40 and FEMA 356.
