Analysis of Stress Response for the Super High Rise Double-tower Connected Structure with the Trusses of Changing Rigidity

摘要

According to the current "Construction structure load standard", in this paper, on the base of building a FEM of super high rise DTCS that with connected trusses and a single tower without connected trusses, the mechanical property of each was analyzed by using ETABS, a three-dimensional finite element software. The contrasted result indicates that with connected trusses the double-tower connected structures have better performance and higher structural effectiveness. This feature is more clearly seen with the increases of the truss' rigidity. The stress of the truss shows certain regularity with the alteration of the truss' stiffness and location.
