With economic development, improving people's living conditions, the biggest problem facing the development of residential buildings city construction land is extremely nervous and the total lack of construction funds. National norms strictly limits the total number of layers and the total height of the masonry structure, 8-18 storey building in the city is usually a framework structure system, the total construction cost upward trend. Therefore, the reinforced block masonry shear wall structure by the Ministry of Construction as the most important new structure of the system, a new type of high-rise building structure type. This article discusses the reinforced masonry shear wall with vertical and horizontal reinforced concrete hollow block masonry and filling the building structural members in the form of concrete core columns, the structure is a new high-level structure form. Concrete block wall the direction of reform, reinforced masonry withstood the test, carried out in the earthquake zone, reinforced masonry shear wall structure, and vigorously promote the application of reinforced masonry shear wall The structure has a very important significance. Reinforced concrete block shear wall structure with prefabricated concrete structure of the force characteristics in developed mature software packages before the PKPM series SATWE procedures for the calculation and analysis of internal force. Shear wall body input, 190mm thick block wall C10 to C20 cast-in-place concrete wall input, as well as the corresponding analytical parameters make the necessary adjustments. Internal forces generated by SATWE results can be used as a basis for the calculation of block shear wall further reinforcement of the horizontal force of the displacement of the structure layer and the layer displacement angle can be used as a basis for deformation check. To output will SATWE file into a spreadsheet EXCEL format, the preparation of the pier and coupling beam reinforcement program, simplifies the computational effort of repeated reinforcement. Specific examples of projects on the design and application of reinforced concrete block shear wall structure are discussed. The results show that the economic benefits generated by the use of small concrete hollow block, the social benefits are obvious. With the gradual deepening of the R \u0026 D work, practical experience has been accumulated, will gradually overcome the technical difficulties, the market advantage of this new structure will become more apparent, the large-scale application in the construction sector is also just around the corner.
