Framework structure which classes? Housing construction structure which several types?


Classified according to the structure of housing construction steel structure is the main component of the load-bearing steel material construction, including cable structures.Steel, reinforced concrete structure is the main component of the load-bearing steel, reinforced concrete construction. The reinforced concrete structure is the main component of the load-bearing is constructed of reinforced concrete. Including shell structure template situ structure and the use of sliding mode, up board construction of the reinforced concrete structure of the building. The hybrid structure is the main components of the load-bearing reinforced concrete and brick and wood construction. Such as a beam of the house is made of reinforced concrete, brick wall is load-bearing walls or beams are constructed of wood, the column is constructed of reinforced concrete. Brick and wood is the main component of the load-bearing brick, wood construction. Such as a housing frame wooden room, brick walls, wooden construction. Other structure who does not belong to the above structure houses shall such. Such as bamboo structure, brick arch structure, cave. The main difference is the superstructure, the frame structure, a shear wall, the vertical stiffness of the frame structure is not strong, senior or super high-rise building frame structure especially! To solve this problem it is to use shear walls you can go frame structure, frame structure, residential refers to the load-bearing beams and columns of reinforced concrete poured pounded with precast aerated concrete, expanded perlite, pumice, vermiculite, Tao bad light sheet wall splitting assembled whileResidential. Suitable for large-scale industrial construction, high efficiency, good quality of the project. The frame structure constituted by the beams and columns, smaller member section bearing capacity and stiffness of the frame structure are lower, it's the mechanical characteristics of similar vertical cantilever shear beam, the higher the floor, the horizontal displacement of the slower, high-level framework in aspect both directions under great horizontal force, In this case, cast floor also as a beam working together, the role of the prefabricated floor is not considered, the frame structure of the wall is filled wall, from envelope and separated the role of the characteristics of the framework structure is provided for the construction of the flexible use of space, but poor seismic performance. 1. Frame - shear wall structure, the called frame structure, it is the combination of the two systems of the frame structure and shear wall structure, drawing on their respective strengths, both for building layout provides a greater use of space, but also has good lateral force resisting performance. Wall structure in the shear wall can be set individually, can take advantage of the wall of the elevator shaft, stairwell, tube wells.Therefore, this structure has been widely used in various types of housing construction. 2.The deformation of the superstructure, scissors curved. As we all know, the deformation of the frame structure is relatively small deformation shear, upper layer, the lower layer relative deformation. Shear wall structure deformation for bending, large relative deformation in the upper layer, the lower layer is relatively small deformation. Wall structure, due to the deformation compatibility of the two structures work together to form a curved shear deformation, thereby reducing the pending cut the layer relative displacement ratio and vertex displacement ratio, the lateral stiffness of the structure has been improved. 3. Horizontal load shear walls to withstand. From the characteristics of the force, due to the lateral stiffness of shear wall in the wall structure is much larger than the lateral stiffness of the frame, the horizontal loads, under normal circumstances, about 80% more than in shear wall commitments. Therefore, the frame structure under lateral loads assigned story shears, than the kind of evenly distributed along the height closer to the moment of layers beamed beneficial to reduce the beam-column specifications, to facilitate construction.
