Abstract: along with the social economic prosperity, small high-rise buildings in our country is developing rapidly. Design thought are constantly updated. Structure system has become more and more diverse. Small high-rise steel reinforced concrete frame structure is more and more widely used in construction, small high-rise steel reinforced concrete frame structure design has a bright prospect of application. Our country has not been formed the corresponding standard, still need to do a lot of research work.

1 small high-rise steel reinforced concrete structure housing the basic structure of form

1.1 frame structure frame structure characteristics of large width, flexibility is good, the seismic performance is good, the cost is low, but because the column section partition wall thickness and cause greater than the column Angle, the influence of furniture decorate convex and beautiful, because sometimes in the residence of the room space irregularities and cause of the column to decorate.

1.2 a frame shear wall structure frame structure in the arrangement of a certain number of shear wall is a part of the frame shear wall structure. It is a small high-rise residence with the extensive application in a main body form. Its characteristic is planar flexible, applicability, reasonable structure, can make the frame, shear wall two have different deformation performance resist lateral force structure is very good cooperative play a role.

1.3 large bay multi-ribbed slab frame shear wall structure with the development of The Times and the improvement of people's living standard, originally built small bay is shear wall system in residential building function, the limitation of becomes

increasingly apparent. In terms of strength, from small bay in the role of the wall structure can't get enough of the play, and the excess shear wall decorate also lead to large earthquake force, increase the project expenses, moreover, due to the structure, it also increases the weight larger based investment, therefore, large bay multi-ribbed slab frame shear wall arises at the historic moment. Main wall of a room in an

old-style house reached 4.5 m to 7.5 m, 7.5 m deep ~ 1 lm, indoor generally no bearing of horizontal and vertical wall wall, can according to the different requirements of household space, along with the family flexible change still can decorate afresh.

1.4 short shear wall structure short-shear walls (wall limb section height and thickness ratio is 5 to 8 of shear wall being in special-shaped columns) and general shear wall, because this kind of structure system between the building function, structure and investment efficiency, energy-saving index to good effect, has many aspects such as into small high-rise residential main structures.

2 small high-rise residential reinforced concrete structure design of the key points 2.1 level load gradually become reinforced concrete structure design of the control factors in low-rise residential, often is by gravity, as a representative of the vertical load control of the reinforced concrete structure design; And in residential building, although the vertical load of the reinforced concrete structure design still produces the important influence, but horizontal load will be the control factors. For a particular architecture, it is substantially the vertical load value; As a horizontal load of wind load and earthquakes, its value is with the dynamic characteristics of the different and there will be great changes.

2.2 axial deformation nots allow to ignore to the frame system or frame shear wall system of a small high-rise residential, framework of the axial compressive stress column are often more than side pillar of the axial compressive stress, and it makes column in the axial compression deformation is greater than the side columns axial compression deformation. When the house is very high, such differences axial deformation will reach a lot of value, the consequences of the continuous beam is equivalent to the middle, bearing produce subsidence of the continuous beam in the
