Abstract: The main aspects of the structural design is introduced on the Municipal Project of Guangzhou Zhujiang New Town Core Area. Several new constructions and measures are successfully created and adopted in this project, such as the steel shear key with donut shape, reinforced concrete slab cored with teel tube, flexible steel case (plate) within post-pour band etc. As an entire embedding underground building, the behavior character under earthquake excitation is analyzed and described. Measures and methods to span the subway tunnel below the structure are introduced at last.
Keywords: steel shear key with donut shape; steel tube cored slab; flexible steel case (plate) within pos-pour band
