Chapter I General Provisions
Article 1.0.1 The structural design of reinforced concrete high-rise buildings shall be closely coordinated with the building, equipment and construction, and pay attention to the characteristics of high-rise building structures. Be safe, applicable, advanced in technology, and economically reasonable. According to the characteristics of the structure, actively adopt mature new technologies, new processes, and new materials. Under the premise of ensuring quality, the design scheme should facilitate construction and help speed up construction.
Article 1.0.2 This code applies to high-rise civil reinforced concrete structures of 8 floors and above, and their building height and structural type shall comply with the provisions of Section 1 of Chapter II of this code.
This code applies to high-rise buildings that are not designed for earthquake resistance and high-rise buildings designed for earthquake resistance with a fortification intensity of 6 to 9 degrees.
Article 1.0.3 The fortification intensity of high-rise buildings shall be determined in accordance with the documents (drawings) approved and issued by the authority stipulated by the state. In general, the basic intensity can be used. For areas that have been divided into fortification zones, seismic fortification can be considered according to the approved seismic motion parameters.
Article 1.0.4 The importance of high-rise buildings with seismic design shall be determined in accordance with the "Code for Seismic Design of Buildings" GBJ11-89.
Article 0.5 In the structural design of high-rise buildings, attention should be paid to the selection and construction of the structure, and the structural system and flat facade layout plan with good seismic and wind resistance and economical and reasonable performance should be selected. The connection should be strengthened in the structure. In the earthquake-resistant design, the overall earthquake-resistant performance of the structure should be guaranteed so that the entire structure has sufficient bearing capacity, rigidity and ductility. Article 1.0.6 This code is based on the principles of the "Uniform Standard for Building Structure Design" GBJ68-84; the symbols, measurement units and basic terms meet the requirements of the "General Symbols, Measurement Units and Basic Terms for Building Structure Design" GBJ83-85. Article 1.0.7 This code is compiled in accordance with the current standards of my country, "Design Code for Foundation Engineering Construction Standards", "Load Code for Building Structures", "Design Code for Concrete Structures", "Code for Seismic Design of Buildings" and "Concrete Structure Engineering Construction and Acceptance Code" and other relevant codes, and is supplemented by combining the characteristics of high-rise buildings, practical experience and scientific research results. In addition to complying with this code, the design and construction of high-rise building structures should also comply with the provisions of relevant national codes.
