Report of a framework of our multi-storey concrete

structure literature review

I Introduction

With the development of society, reinforced concrete frame structure building more and more common. As the reinforced concrete structures and masonry structures , compared with large carrying capacity, structure, light weight, good seismic performance, construction of the advantages of higher level of industrialization ; and steel structure as compared with the low cost, wide range of sources, fire, good structural rigidity, use and maintenance cost is low. Therefore, in our reinforced concrete structure is the most commonly used multi-frame structure type. In recent years, the world multi-storey reinforced concrete frame structure is developing very rapidly, application of many.

General framework of the structure is a floor, beams, columns and foundation composed of four kinds of bearing components, the main beams, columns and form the basis of plane frame, the plane frame connected by the beam of the space structure system. at a reasonable height and number of layers of the case下, frame Jiegou able to provide larger building space, Allocation Comparison of Linghuo may be suitable for Duozhonggongyi and Shiyong the functions.

Multistory reinforced concrete frame structure design can be divided into four stages: First, program design, and second, structural analysis, third, component design, the four are drawn drawings. Structural analysis and component design is structural design calculation stage, in the modern, from computer to the job, often calculated by PKPM modeling. However, the structure calculation and not a substitute for structural design. A good structure, an important prerequisite for the design, organization and should be reasonably comprehensive solution structure of the force transmission system, transfer method, a good structure of the program is a good structure, an important prerequisite for the design.

II On the frame structure design literature review

2.1 Frame structure of the advantages and disadvantages

Frame structure system is connected by the beams and columns made of. column joints (called nodes) is generally rigid, and sometimes for the ease of construction and other construction requirements, but also can be hinged or made part of the node semi-articulated. column bearing generally fixed support, when necessary, can also be designed to hinge bearings. frame structure can be divided into integral cast, fabricated, cast assembled.

Frame structure of the layout flexibility and easy process to meet the architectural features and a variety of health requirements. At the same time, through rational design, the frame
