The key to the success of the design of the steel structure building design is the technical conception and performance. In the deepening of the scheme design, it is necessary to cooperate closely with the structural engineer, the equipment engineer, and even the mechanical engineer. At this time, technical performance is a natural thing. Whether it is spatial form, formal volume or structural nodes, it is very important to influence its architectural design and performance. The following will illustrate this point from several aspects. (A) Technical performance of steel structure architectural design The conception of architectural image is a creative process of conceptual image, which is one of the difficulties in architectural creation and one of the core issues that have received much attention in architectural design. Looking back at the development of the relationship between architecture and science and technology since the Industrial Revolution, we can clearly find the hysteresis of architecture's response to technological change, which reflects the deep status of architecture in social culture and the relationship between architecture and people's way of life. close relationship. In addition, the emerging information revolution in modern times is widely permeating and involving every field of social activities, so that modern scientific thinking is integrated into architectural design, and great changes have taken place in the planning, architectural and landscape design methods of new projects. The purpose of architectural design has also developed from the pure pursuit of beauty to the pursuit of reasonable solutions to problems, which has fundamentally changed people's previous understanding and design methods of architecture, and finally affected the traditional architectural views formed by human beings for thousands of years, such as high Jipai architecture is its main representative, which embodies superb skills with exquisite nodes and fine processing, and designs and "manufactures" buildings with a higher level of craftsmanship. (B) The detailed design of steel structure buildings has higher requirements. The higher the complexity and refinement requirements of steel structure building design, the higher the requirements for detailed design. Because detailing determines whether a place is finally confirmed and its quality. In modern steel structure buildings, various metal structural rods and the details of the nodes connecting the metal rods are often exposed, giving the building a strong sense of technology, such as the Pompidou Art and Culture Center in Paris, France, built in 1977. , its steel columns, steel beams, trusses and other structural components are exposed, which not only reflects the beauty of technology, but also reflects the wisdom and ability of people. Therefore, it is very important for steel structure buildings to maintain high design requirements for detail quality, and special attention should be paid to steel structure buildings. (C) Architectural planning is also an influencing factor for the design and performance of steel structure buildings. Because steel structure building design has the general attributes of architectural design, architects do not design at will, and the owner's design task book affects the architect's plane and design concept. The effect is significant. Clients expect better performance from designers, and they expect designers and market experts to be more productively involved in the decision-making process of their final product. At this stage, the construction project emphasizes the overall design and the coordination between professional designers, market experts and developers. The design process includes continuous exchange and integration of information and knowledge. In addition, the specialization of steel structure buildings can not only provide a wealth of design knowledge, but also effectively integrate design resources and market experts to be jointly responsible for the building, so that the design and the owner's business intentions can be effectively combined to make the project profitable and reduce risks. Architectural characteristics of modern steel structures (1) High degree of pre-engineering, reduced construction costs, and shortened construction period It has certain versatility and interchangeability with building components of different manufacturing methods. At the same time, the pre-engineering of steel structure buildings integrates material processing and installation, which greatly reduces the construction cost; and accelerates the construction speed, so that the construction period can be shortened by more than 40%, thereby speeding up the capital turnover speed of real estate developers and making the construction energy efficient. put into use earlier.

(2) Steel structure buildings can meet the requirements of super height and super span. The steel structure is uniform, close to the isotropic homogeneous body, with high strength and high elastic modulus. The ratio of its density to strength is much smaller than that of masonry, concrete, and wood. Under the same stress, the steel structure has a small self-weight, so that it can be made into a structure with a large span and a high height, as well as a flexible structural shape. Now humans have the ability to build super-large domes with a span of more than 1,000 meters and super high-rise buildings with a height of more than 1,000 meters and a maximum of 4,000 meters. And the combination of steel cable and membrane structure to form a cable-membrane structure system can better meet the requirements of the building on the span, making this type of building a landmark building. The membrane structure covers an area of ​​28,000 square meters. The London Millennium Dome, a landmark building built by the British government to welcome the 21st century - a large-scale comprehensive exhibition building is also a cable-membrane structure system with a dome diameter of 320m. (3) The design and function of the building and the structure are integrated to make the building more functional. In the steel structure building, the structure becomes an important factor in the image composition. The shape, components and nodes of the structure lead and restrict the building to a large extent. image of. Only when the design and function of the building and the structure are integrated, can the building be more functional, so that the subsequent design links can be carried out to create a steel structure building that integrates technology and art. This feature of steel structure buildings is reflected in many proposals in the bidding plan of the National Stadium for the Beijing 2008 Olympic Games. For example, the opening and closing scheme designed by the Architectural Design Institute of Tsinghua University, two semi-circular glass tops are set in the center of the large roof of the stadium, and at the same time rotate and slide in parallel to complete the opening and closing of the large roof; another example is the venue of the China Architecture Design and Research Institute. The appearance of the scheme is the structure of the building, the image is perfect and pure, and the function and structure have achieved a perfect unity; there is also a folding scheme designed by the Japanese Zhu Style Association Architecture Office. The roof is supported by a cantilevered steel frame structure, which can be completed within 30 minutes. The action of opening and closing ensures that the competition and activities throughout the year are not affected by the weather. (4) Raw materials can be recycled, which is conducive to environmental protection and sustainable development. The development of steel structures is of great significance to my country, which is very short of resources and energy, because China is the largest country in the world of brick masonry buildings and concrete buildings. Steel is a high-strength, high-performance material with high recycling value, as well as scraps, which do not require moulding. At present, the internationally eye-catching new residential products have been introduced into my country, and their characteristics of environmental protection and energy saving are mainly reflected in two aspects:

(a) This type of residence adopts a fully enclosed thermal insulation and moisture-proof system, with small temperature changes and low heat loss. Whether it is winter or summer, it has a comfortable living environment. When the outdoor temperature is 0 degrees Celsius, the indoor temperature can still be maintained above 17 degrees Celsius; when the outdoor temperature reaches 30 degrees Celsius, the indoor temperature is only about 21 degrees Celsius. (b) Compared with brick-concrete structure houses, it can save energy by more than 60%, air-conditioning equipment can save power consumption by more than 30% in winter and summer, and the waste utilization of the structure is 100%. Compared with brick-concrete structure, under the condition of the same floor height, Steel structure maintenance wall area is small, saving energy required for air conditioning and reducing maintenance costs.
