With China's three decades of rapid economic development and the continuous improvement of the national life, housing is also increasing, mainly from the multi-storey brick structure development to the reinforced concrete structure. Continuously improve the level of urbanization in China in recent years, the steady decline of the construction land, small high-rise residential and high-rise residential, has become the most important type of residential development projects in recent years. Because of small high-rise residential high-rise residential structure, there is the possibility of selection of a variety of structures. Therefore, in order to facilitate the selection of small high-rise residential structures in the future, various structures of the small high-level selection, economy of comparative analysis, in order to provide guidance for the selection of the structural design program. In this article attempts to study like the Pearl River Delta, Zhongshan City, a small high-rise prototype simplified and roof section, select only the standard layer analysis object, respectively, using different structural systems, structural analysis, in the original structure shear wall, column position without major changes to the structure of the vertical component position is not the case of a major adjustment, to compare the mechanical properties of the earthquake, and analyzed on the basis of differences in economic indicators. Comparison of economic indicators, due to the civil engineering part of the cost impact of the largest concrete consumption per square reinforced dosage. Therefore, during the economic analysis select different structural system square content steel and concrete usage. In addition, due to the frame structure in pure residential construction, due to its impact on the function of the building plane, that can not be overcome gel column, exposed beams and other shortcomings, thus making the selection of the structure of pure frame structure with a rectangular column frame no longer included in the analysis, the analysis focuses on the general wall structure, short shear wall structure with special-shaped columns frame shear wall structure. Finally, a summary of the characteristics of a variety of structural systems, and a comparison of the performance of a variety of structural systems and their amount of steel, concrete dosage different; the seven degree earthquake acceleration of 0.10g conditions obtained ordinary shear wall structure is a small high-rise residential building in the most economical, the most applicable to the conclusion of a structural system. To provide a scientific basis for a small high-rise structure design selection.
