| Abstract: | The mansion of Beijing Television Center is a frame-support steel structure constructed by "Hanging on the top substructure and supporting on the bottom substructure"(HTSB)technology.This paper carries out the numerical simulation analysis on the whole construction process by using the birth and death element technology of ANSYS for the super high-rise steel structure of Beijing Television Center.Story by story loading and structural stiffness matrix step by step updating are considered.The detail calculations for the change of the structural stress during the construction process are completed.The results of calculation provide direct instruction for the realization of HTSB technology,and similar structure design and construction can take this as reference. |
