Emphasis: in the data provided to the architectural discipline, if it is necessary to determine the location of the shear wall, the structural discipline needs to use the PKPM program for modeling and calculation.
.
The structural design should be paid attention to in the scheme stage.
The scheme design is not only the architectural professional drawings and descriptions, but also the integration of all disciplines.
In the evaluation of engineering scheme design, the bidding method is not adopted, and the design scheme needs to be comprehensively introduced to the investment and construction unit; Not only the architecture specialty (of course, the main specialty), but also other related specialties need to be introduced.
The structural discipline first receives the design basis and brief design description provided by the architectural discipline.
2.
For specific engineering project design, the provisions of this regulation shall be reasonably selected according to the project content and design scope when implementing this regulation.
Structural designers should have a deep understanding of the scale, nature of use, design standards and investment costs of the project, and select a technologically advanced, economic and reasonable structural scheme based on the preliminary scheme of the construction discipline and the structural design concept and experience of the structural designers themselves.
Be prepared for the introduction of the design scheme.
When the design contract has other requirements for the preparation depth of design documents, the preparation depth of design documents shall meet the requirements of this regulation and the design contract at the same time.
Especially for the complex large public buildings, there must be a clear structural scheme, which can withstand the challenge and comment in the scheme design evaluation.
When reusing the drawings of other projects, the conditions and contents of the original drawings should be understood in detail, and necessary accounting and modification should be made to meet the needs of new design projects.
4.
Civil building engineering should generally be divided into three stages: schematic design, preliminary design and construction drawing design; For civil construction projects with simple technical requirements, with the consent of the relevant competent departments and the agreement of not making preliminary design in the contract, they can directly enter the construction drawing design after the approval of the scheme design.
③ Understand the local building materials, such as steel grade, the highest concrete use grade, commercial concrete, and filling masonry materials.
Site survey: ① Whether there are obstacles affecting the foundation construction of the new project around the terrain, landform and the relationship between the new and old buildings.
4.
If there is no geological report, refer to the geological report of adjacent buildings.
According to the initial geological report, understand whether there are adverse geological conditions in the project construction site (such as liquefaction, collapse, fault zone, soft soil, uneven soft and hard, landslide, etc.), standard frost depth, whether frost heave, groundwater conditions (pay special attention to whether the groundwater is corrosive), and site type.
In the scheme design stage, there are no drawings for the general structure discipline, and the structural system, column grid and wall layout are expressed in the relevant drawings of the architecture discipline, while the structural design scheme should be described.
3.
Special local engineering practices and special requirements of Party A.
In the case of contracting the project to several design units or implementing design subcontracting, the depth of the design documents shall meet the design needs of each contractor or subcontractor.
The designer confirms the architectural overview and design scope, and puts forward adjustment suggestions and feedback to the architectural discipline.
(3) Construction drawing design documents shall meet the requirements of equipment and material procurement, non-standard equipment production and construction.
01 The structural professional designers in the design stage of the scheme design should: determine the safety grade of the building structure, the design service life and the seismic fortification category of the building; According to the functional requirements of the building, the structural selection is determined by comparison of multiple schemes.
The scheme design documents are also used to handle the approval formalities of engineering construction.
Each stage has the same content, but the design depth is different and should be deepened gradually.
（2） The structural discipline receives the data provided by each discipline.
If the project is large and complex, the structural discipline receives the data provided by the water supply and drainage, HVAC and electrical disciplines according to the project needs.
② Understand the relevant conditions of each discipline, such as the direction and location of the entrance of water, heating and electricity, the direction and current situation of underground pipelines.
The requirements for the preparation depth of design documents in this regulation are universal.
On May 11-13, 2023, the Eighth International Conference on Seismic Technology of Building Structures in Hangzhou (click here for details) stipulated in the General Principles that 1.
The depth of preparation of design documents at each stage shall be in accordance with the following principles: (1) The schematic design documents shall meet the needs of preparation of preliminary design documents.
(Note: For the bidding scheme, the depth of design documents shall meet the requirements of the bidding document.) (2) The preliminary design documents shall meet the requirements of preparing the construction drawing design documents.
Actively familiar with the structural forms, relevant specifications and technical measures that may be used in the project.
The structural scheme of any engineering project is very important, which is directly related to the safety, use, construction period and cost.
④ Understand relevant local regulations and design standards.
5.
Table 1.2 The structural discipline receives the data provided by the water supply and drainage, heating and ventilation, and electrical disciplines.
Table 1.1 The structural discipline receives the data provided by the architectural discipline.
2.
The scheme design document is the necessary content for the design bidding, and it is very important.
⑤ Local foundation treatment capacity and methods.
⑥ Local construction technology level.
The structural design shall be carried out in a planned way in different periods and batches according to the actual situation of the project.
By strengthening the execution of the structural design process, errors, omissions, collisions and deficiencies are reduced, the design quality is guaranteed, and the work efficiency is improved.
（1） Plan preparation 1.
3.
The description of the structural scheme design is very important, especially to briefly and popularly explain the rationality and progressiveness of the selection of the structural system of the project.
The design content of each discipline at each stage is orderly realized by submitting data to each other at each stage.
For some projects, such as large-span gymnasium buildings, airport terminal buildings, cinemas and high-rise buildings beyond the limit, the introduction of structural design scheme is an important content.
In the design, national, industrial and local building standard design shall be correctly selected according to local conditions, and the name of the applied atlas shall be indicated in the drawing directory or construction drawing design description of the design document.
