Abstract:Shenzhen Huarun center is a complex structure with many transfer members and the surpassing length of structure surpasses the limit of the code. Based on these features of such a special project, a multi-function structure measures are adopted to guarantee the safety and economy, to fulfill the architecture design of the construction. The measures, including steel tube-reinforced concrete composite columns in layers, semi-hollow steel reinforced concrete composite transfer beams, lattice steel beams, shearing steel reinforced concrete composite transfer beams etc., are used, leading to a good structural system in stiffness, ductility and stability. Furthermore, the essential technology, application characteristic and analysis of the design and construction method for a 33-meter span lattice steel transfer beam are introduced.

Keywords: steel tube-reinforced concrete composite column in layers; lattice steel beam; semihollow steel reinforced concrete composite transfer beam; shearing steel reinforced concrete composite transfer beam; ultra long structure
