Tubes in the tube structures are divided into the thin-wall tubes enclosed by shearwalls and frame tubes enclosed by thick-column frames or wall frames. 2.1.8 Frame-corewall structure It refers to the tube structure composed of core tube and peripheral spare-column fr?me. 2.1.9 Tube in tube structure It refers to the tube structure composed of core tube and peripheral frame tube. 2.1.10 Mixed structure, hybrid structure It refers to the building structure, composed of steel frame (frame tube), section steel concrete frame (frame tube), steel pipe concrete frame (frame tube) and reinforced concrete core tube, jointly bearing the horizontal and vertical actions. 2.1.11 Structural transfer member3 Basic Requirement of Structural Design3.1 General Requirement 3.1.1 Seismic precautionary intensity of tall buildings must be determined according to the documents (drawings) approved and issued as the limits of authority specified by the state. Typically, the basic seismic intensity determined according to Seismic Ground Motion Parameter Zonation Map of China shall be adopted as the seismic precautionary intensity. 3.1.2 As for the tail concrete buildings adopting seismic design, the seismic precautionary category shall be determined according to the requirements of the current national standard "Standard for Classification of Seismic Protection of Building Constructions" GB 50223 . Note. Category A. Category B and Category C buildings in this specification are short for buildings of particular fortification category. major fortification category and standard fortification category respectively specified in "Standard for Classification of Seismic Protection of Building Constructions" GB 50223. 3.1.3 Concrete structures of tall building may adopt such structural systems as frame, shearwall, frame-shearwall, slab-column sheanvall and tube structure. 3.1.4 Tall buildings shall not adopt severely-irregular structural system and they shal l meet the following requirements. 1 They shall be possessed of necessary bearing capacity, rigidity and ductility; 2 The whole structure shall be prevented from losing the abilities to bear gravity load, wind load and seismic action due to the failure of partial structure or members; 3 Effective strengthening measures shall be taken for potential weak positions. 3.1.5 Structural system of tall buildings shou ld also meet the fo llowing requirements. 1 Vertical and horizontal layout of structure should enable the structure to have reasonable rigidity and bearing capacity distribution, and avoid formi ng weak positions due to the partial mutation of rigidity and bearing capacity or structural torsion effect; 2 The structural system shou ld have several defense lines in the seismic design. 3.1.6 Measures should be taken for concrete structures of tall bui lding to reduce the adverse effect of non-load effects such as concrete shrinkage, creep, temperature change, and foundation differential settlement. Various cmtain walls for buildings should be adopted for the outer walls cif tall building whose building height is not less than l SOm. 3.1.7 Non-structural members of tall building such as filler wall and pa1tition wall should adopt various light materials, shall reliably connect with the major structure and shall meet the requirements for bearing capacity, stability and deformation . 3.2 Materials 3.2.1 Concrete structures of tall building should adopt high-strength and high-performance concrete and high-strength reinforcement; where the members have larger internal force or h... ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
