Suzhou Science and Technology Building Office main building using a large-span steel truss side superstructure conversion. The structural design features and the related measures taken by the main office building are introduced. According to the multi-program calculation and analysis, the influences of the form and connection method of the 3 ~ 4 conversion steel truss diagonal bars, the stress ratio of components and their influence on the surrounding components and the overall structure are analyzed in detail , The design of the key nodes of the converter steel truss is optimized and the design concept of using the concrete filling core to ensure the stability of the bar is put forward. The elastic structure and static analysis of the whole structure are analyzed. The results show that the structure satisfies Regulating the requirements of complex high-rise building structures ensures structural safety.
