1 Basic principles of structural design of high-rise buildings
1. 1 Optimization principle of structural scheme
In daily study and work, many people have written papers. Thesis is a comprehensive style, through which we can directly see a person's comprehensive ability and professional foundation. So, have you understood this paper? The following is my paper on the problems and countermeasures in the structural design of high-rise buildings. Welcome to read the collection.
Architectural structural design is the first step of architectural construction, and a good quality building cannot be separated from a good structural design scheme. Architectural structure design is a very important link in building construction, and building construction cannot be separated from the guidance of architectural structure design scheme. When making the structural plan of a building, it is necessary to collect information about the surrounding environment of the building and make a reasonable design according to the location of the building. In addition, in the design, it is also necessary to consider the economy of the building, construction technology and the influence of construction, so as to design the best construction scheme.
1.2 principles of saving building materials and resources
An important task of architectural design is to improve the utilization rate of building materials and reduce the use of building materials. Therefore, before the actual construction of a building project, the relevant designers must carefully study the engineering drawings and make plans for the use and saving of building materials in advance. Under the premise of not affecting the overall construction season and quality of the project, various factors related to building materials, such as logistics cost, processing cost and storage cost, are comprehensively considered. , so as to reduce the cost as much as possible. In addition, when choosing building materials, don't blindly pay attention to the price, but also consider the quality of building materials, such as the use of steel bars. Try to use high-strength steel bars, which have the advantages of high strength and outstanding performance, and the use effect is much higher than that of ordinary steel bars. Comparatively speaking, they are more cost-effective.
2 Characteristics of structural design of high-rise buildings
2. 1 control index
Because of the height of floors, the construction of high-rise buildings is very different from that of grass-roots buildings, so when formulating the structural scheme of high-rise buildings, the design emphasis is also different. In the structural design of high-rise buildings, structural lateral displacement is a very important design factor, so we must pay attention to controlling the structural lateral displacement within a certain range when making the structural design scheme of buildings.
2.2 Axial deformation
Another very important factor in the structural design of high-rise buildings is axial deformation. In the construction of high-rise building, once the vertical load value becomes larger, the vertical frame will produce very large axial deformation, which will destroy the bending moment of continuous beam and then affect the overall structure of the building.
2.3 horizontal load
Horizontal load is a very important factor in building structure design. In the design of building structure, the axial force caused by vertical load is proportional to the first power of the total height of the building, and the overturning force caused by horizontal load and the axial force caused by vertical members are also proportional to the second power of the total height of the building. If the building height increases, this value will also increase, which has a great influence on the whole building structure.
3 Problems in structural design of high-rise buildings
3. 1 The structural design of high-rise buildings is arbitrary and unorganized.
The most important reference for building engineering construction is the design drawing of building structure, which is also a concrete index in the construction process and plays a very important role in building structure design and actual engineering construction. There are some minor problems in the design drawings of building structure, which will be magnified several times or even dozens of times in the form of building structure in actual construction. Therefore, in the design of building structure, we must pay attention to the use and identification of design drawings. However, in the current process of building structure design, there are still some problems in the application of drawings, and some key information is not displayed in the drawings, such as the seismic design of buildings, the crack resistance grade of buildings, or the quality standards of building construction materials. If the designers do not consider the overall design of the building structure comprehensively in the later period, some omissions will seriously affect the construction quality of the building project.
3.2 The structural design of high-rise building is not in conformity with the regulations.
The non-compliance of the structural design of high-rise buildings is mainly reflected in the selection of building materials. With the continuous improvement of China's economic level, the construction industry has been greatly developed, and behind the prosperity of the construction industry, the market competition is more intense. This makes some enterprises, in order to pursue profits and expand market share, start to reduce their own construction costs, and the main means to reduce construction costs is to adjust the grade of building materials. Many enterprises adjust building materials without authorization when designing building structures. For example, building materials with low steel content are used to reduce construction costs, and some low-quality building materials are used. This will not only have a great negative impact on enterprises, but also seriously threaten the safety of people's lives and property, which is also the reason for the phenomenon of "crooked buildings" and "fragile buildings" in China.
4 Effective solutions for structural design of high-rise buildings
4. 1 Improve the design drawings of high-rise buildings and cultivate a rigorous working attitude.
Attention should be paid to the use of design drawings in building structure design. In the process of structural design of high-rise buildings, relevant designers should consider some small and important data and clearly mark them on the design drawings to avoid omitting some important information for convenience. Because the actual construction of high-rise buildings is carried out in strict accordance with the structural design drawings of high-rise buildings, once unclear or unclear data information appears in the drawings, it will have a great impact on the overall construction of high-rise buildings. In addition, when designing drawings, designers should adhere to a rigorous working attitude, take the design work seriously, avoid carelessness, and check the completed design drawings repeatedly to ensure the accuracy of the design drawings. At the same time, designers should also modify or make up for the problems or missing data found in the drawings in time to ensure the construction quality of the building project.
4.2 Strengthen the stiffness design of high-rise building structure to meet the actual needs of the building.
The stiffness of high-rise building structure depends on the steel content of building materials. Therefore, in the process of high-rise building design, if the design with low steel content is adopted, the project will have great security risks. Therefore, construction enterprises must attach importance to the stiffness design of high-rise buildings to ensure the engineering quality of high-rise buildings. Of course, the stiffness of building structures will vary with different geological conditions. For example, in plain areas, the geology is relatively stable, and the stiffness requirements for high-rise building structures are relatively low, so building materials with slightly lower steel content can be used; In mountainous and hilly areas with complex geological conditions, it is necessary to have stricter requirements on the stiffness of building structures and adopt building materials with high steel content. To sum up, construction enterprises cannot remain the same. In the process of structural design of high-rise buildings, we should adjust measures to local conditions, not only consider the profits of enterprises, but also design the most suitable structural stiffness requirements in combination with the actual situation.
5 concluding remarks
The foundation of high-rise building construction is the design of high-rise building structure. Because of this, the design quality of high-rise building structure will directly affect the later construction quality of high-rise building. At the same time, with the continuous development of our society, people's demand for buildings is also developing in a diversified direction, and it is precisely because of the changes in people's needs that the problems of high-rise building design are increasing day by day. Therefore, in the current fierce competition environment, if construction enterprises want to develop in the long run, they must solve the problems existing in the structure of high-rise buildings and improve the construction quality and level of construction projects. Only in this way can we make better contributions to society and enterprises develop better.
