We live in the housing, because of the height and use of the different construction time, resulting in the structure of different, but also decided that the building's anti-seismic capacity is not the same. What kind of house is the most anti-seismic? Let us know together.
Anti-seismic level of STEEL STRUCTURE ★ ★ ★ ★
Characteristics: Steel structure is the main structural material. Steel is characterized by high strength, light weight, at the same time due to the uniform quality of steel materials and strong toughness, can have a larger deformation, can well withstand dynamic loads, has a good seismic capacity.
Application: However, because the construction cost of steel structure is relatively high, the current application is not very common.
General Ultra high-rise buildings (more than 100 meters) or the larger span of the construction of steel structure, Shenyang City is typical of the steel structure of the five-love market two, shoes and hats shopping malls.
Anti-seismic level of shear WALL STRUCTURE ★ ★ ★ ★
Features: Shear walls are reinforced concrete wall panels to bear various loads caused by internal force, and can effectively control the level of the structure, this shear wall to withstand vertical and horizontal structure of the force called shear wall structure.
Application: Shear wall structure in the high-rise (10-storey and 10-storey residential buildings or more than 24 meters tall building) housing is widely used.
Anti-seismic level of FRAME STRUCTURE ★ ★ ★
Features: Reinforced concrete from the load-bearing columns composed of skeleton, and then hollow brick or prefabricated aerated concrete, ceramsite and other lightweight panels for partitions assembled. The wall is mainly the role of enclosure and isolation, because the wall is not load-bearing, so can be made of a variety of lightweight materials.
In a frame structure, there is also a frame-shear structure, also known as frame-shear wall structure, it is the frame structure and shear wall structure of the combination of two systems, absorbing their strengths, both for building layout to provide greater use of space, but also has good resistance performance. This structure of housing has a very good anti-seismic.
Application: Frame structure is more prevalent in modern architectural design, and most of the buildings we see are frame structures.
Anti-seismic level of brick masonry structure ★ ★
Features: brick-mixing structure of the "brick", refers to a unified size of the building materials, including other dimensions of the special-shaped clay brick, hollow bricks and so on. "Mixing" refers to the reinforcement, cement, sandstone, water according to a certain proportion of reinforced concrete ingredients, including floor, beams, staircases, balcony. These fittings are combined with the load-bearing walls of bricks, so they are called brick-mixing structures. Brick-concrete structure residential generally with multi-layer (24 meters below, residential 10 floors below), its anti-seismic performance than the above three relatively weak.
Application: brick-mixing structure is generally applied in multi-storey or small span buildings, however, because of the rigid structure of brick and concrete, the wall can not be changed, coupled with the recent years of frame structure and shear wall structure application more and more common, in urban construction has rarely applied brick-mixing structure, at present, only some of the suburbs in China or brick masonry structure.
