Conceptual design of high-rise building structure, conceptual design is mentioned more among designers, but people often understand it one-sidedly, thinking that conceptual design is mainly used for some major principles, such as determining the structural plan, structural arrangement, etc.
In fact, nowhere in the design can not do without the guidance of scientific concepts. The rapid development of computer technology provides fast and accurate design and calculation tools for structural design. But don’t be superstitious about computers, you can’t be the slaves of computers, you should be the masters of computers.

Human design is conceptual design. There are many defects in many designs, the main reason is that the correct conception is not adopted in the overall plan and structural measures, that is, the conceptual design is not carried out. 1 Significance and basis of conceptual design.

Concept Design

1.1 Significance of Conceptual Design To be able to make the structure function consistent with the external conditions, to fully demonstrate the advanced design, to give full play to the function of the structure and to obtain coordination with the economy, to better solve the structural processing, and to use the conceptual design to judge the rationality of the computational design.Concept Design
1.2 Basis of conceptual design The working principle and mechanical properties of the overall structural system and each sub-system The principle of design and construction processing The mechanical model and function of the calculation program The practical experience absorbed or accumulated continuously.
2 General principles of conceptual design
2.1 Selecting an appropriate foundation scheme The foundation design should be based on a comprehensive analysis of various factors such as engineering geological conditions, superstructure type and load distribution, the influence of adjacent buildings and construction conditions, and an economical and reasonable foundation scheme should be selected. When designing, the potential of the foundation should be maximized, and the foundation deformation should be checked if necessary. A detailed geological survey report should be included in the foundation design, and some small buildings without a geological report should also be inspected on site and referenced to neighboring building materials. In general, it is not advisable to use two different types of the same structural unit.
2.2 Reasonable selection of structural scheme A successful design must choose an economical and reasonable structural scheme, that is, to choose a practical structural form and structural system. The structural system should have clear force and simple force transmission. It is not advisable to mix different structural systems for the same structural unit. Plane and vertical rules should be sought in the seismic area. In short, it is necessary to comprehensively analyze the design requirements, geographical environment, material supply, construction conditions, etc. of the project, and fully negotiate with the majors of architecture, water, heating, electricity, etc. When necessary, a comparison of multiple schemes should be carried out, and the best one should be used.
2.3 Selection of appropriate calculation diagrams Structural calculations are carried out on the basis of calculation diagrams. Inappropriate selection of calculation diagrams often leads to structural safety accidents. Therefore, choosing appropriate calculation diagrams is important to ensure structural safety. condition. The calculation diagram should also have corresponding structural measures to ensure. The nodes of the actual structure cannot be pure rigid or hinged nodes, but the error from the calculation diagram should be within the allowable range of the design.
2.4 Correct analysis of calculation results Computer technology is generally used in structural design, but due to the wide variety of software at present, different software often lead to different calculation results. Therefore, the designer should have a comprehensive understanding of the scope of application and technical conditions of the program. In computer-aided design, because the program does not conform to the actual situation of the structure, or the manual input is wrong, or the software itself is defective, it will lead to wrong calculation results. Therefore, structural engineers are required to be careful when getting the calculation results Analyze, check carefully, and make reasonable judgments. The designer’s knowledge and experience are still indispensable.
2.5 Take corresponding structural measures and always keep in mind the “principles of strong columns and weak beams, strong shearing and weak bending, strong compression and weak tension”. Pay attention to the ductility of components and strengthen the weak parts. Pay attention to the anchorage length of the steel bar, especially the anchorage length of the straight section of the steel bar. Consider the temperature effects of stress. In addition, it should also be noted that the layout of planes and elevations should be considered according to the principles of uniformity, symmetry and regularity, and multiple lines of defense against earthquakes should be considered comprehensively to avoid the appearance of weak layers and the verification of the limit state of normal use. Conceptual design is required for guidance. .
