Elaborate design of steel structure show four characteristicssteel structural steel disgn Should pay attention to?
Our LiuCi: it is used, economic, beautiful is building engineering design of the three basic principles. A design good engineering should have beautiful appearance modelling, science advanced supporting system, comfortable perfect architectural function, economic and reasonable investment and operation cost, this is the most basic measure of building quality scientific basis.
Reporter: you put forward, elaborate designsteel structure engineeringShould have innovation, high quality, convenient, economic four basic characteristics, please explain in detail.
Our LiuCi: first, in the modernsteel structure engineeringWhen the design innovation is very important, innovation should reflect the progress of science and technology, industrial development and The Times characteristic. Design thinking innovation is essential, but it is by no means for weird, after singular. Engineering design in addition to should have new and accident, also should try to use the new system, new technologies, new processes and new materials. Secondly, high quality insteel structure engineeringWhen the design is also very important.steel structure engineeringShould have reliable bearing capacity, enough stability and stiffness, good joint structure and quality of weld connection. As is known to all, the bearing capacity of structure engineering, stability and rigidity is design of three important indicators. But fromsteel structure engineeringAccident investigation and statistics to see, many of the structural system collapse or failure is due to the improper design structure of the node and the key parts of the welding quality of the cause. Because the welding heat cause steel metallographic change and structure in the high residual stress, often in the welded steel structure body there are several kind of high stress in phase superposition fatal hidden trouble. So the hot rolled steel structure is superior to welding structure is self-evident. Third, is convenientsteel structure engineeringUnique advantages, steel structure components should be designed so as to facilitate the manufacture and installation of the production process. Their structure should be simple, smooth and similar, easy to mass production, mass transportation, cluster assembly, joint should try to use high strength bolt connection. So, be helpful for processing and manufacturing in automation, industrialization of fast, the overall installation, so as to avoid the manual workshop is changed, changed the small production processing model and labor intensive field construction method. Finally, in the premise of safety guarantee, the steel strength design method is reasonable and economic. With the application of prestressed new technology can make full use of the steel elastic strength potential, greatly reduce the amount of steel. I think, innovation, high quality, convenient and economicsteel structure engineeringNot is hard to find, in under the guidance of the concept of innovation, the new system, new technology, new material, new technology advantages combined, and must be reflected in the steel structure of the high-quality goods design.
Reporter: let the steel structure building have innovation, high quality, convenient and economic characteristics, still need to architect and structure division support?
LiuCi Lin: yes.
I think, in the large steel structure building in the beginning of the engineering design, in most architects are not familiar with, don't grasp the modern structure, to ensure that design a high-quality goodssteel structure engineering, need to establish the architects and structure division composed of design team, in order to create reflect innovation, high quality, convenient, economic these four elements of the steel structure excellent project. Architects and structure division the two professional design team is the leading professional many professional, closely cooperate with between them is very important.
Although since twenty century, architecture and structure divided in two subject areas, but the success of many modern large construction projects, all reflect the building and structure of two major the importance of close cooperation. Such as: the 1960 Olympic Games in Rome on large and small sports palace, its main designer neel d professor is the structural engineering, but he in the building also has profound attainments. In 1972, Munich cable net structure of the main home library designer otto professor is building specialized graduation, but his doctoral dissertation topic is and who Cable net structure and throughout And, at the beginning of the project started the building and structure of the joint design team. Charles DE gaulle airport lounge Bridges structure cave in accident, then explaining the French architect Andrew to the structure of strange and improper selection, not steel structure itself.
Reporter: how to avoid and who Waste engineering & throughout And against steel structure characteristics of the architectural representation?
LiuCi Lin: I think, in national engineering project, preparation, bidding, design, construction, operation should in certain regulations constraint, avoid artificial influence and interference. This can avoid some & who Waste engineering & throughout Arise, and can build some and less who Ephemeral engineering & throughout . The reasonable human resource use saved more places where they are needed.
I think, reduce and who Waste engineering & throughout The key is in large engineering project, the selected scheme, inviting public bidding and bidding links should be standardized, sunshine change, should be established corresponding board of review editors, members of the board of review editors in professional, qualifications, proportion, etc should be reasonable matching. In the review process, the board of review editors should accept the competent department, social public opinion supervision. When opinion divergence, shall be submitted to the scheme of the Chinese academy of sciences and the Chinese academy of engineering was evaluated, avoid for individual be fond of, leadership decision, the rejected the plan.
Reporter: you think the future large utilitysteel structure engineeringWhat is the development trend of?
Our LiuCi: from numerous domestic and foreign engineering examples and article review point of view, these largesteel structure engineeringWith a common development trend: building modern design is changed, diversified; Structure ZhangLiHua, spatialization; Processing manufacturing industrialization, automation, Installation construction assembly is changed, block change; Based on GaoJiangHua materials, light-duty; Service function efficiency, generalization.
Nearly 30 years, all over the world in the construction of the large public facilities all follow the scientific, innovative, light, simple principle. For example, from early Saudi Riyadh international stadium, to Seoul, Atlantic, and the Olympic stadium in Athens, and 2002 years later the football World Cup stadium and recent construction of India, Germany, Mexico, Portuguese sports venues are accord with the requirement. 2012 London Olympic Games in the construction of the home, also will be lighter and exquisite light roof structure system. This is and who Sustainable development and throughout The law of the world economy, but also the requirements of our country and who practice The scientific concept of development and throughout The surest way.
Reporter: how to produce high-quality goodssteel structure engineering?
LiuCi Lin: first of all, great efforts should be made to improve the overall design level; Secondly, to improve the healthy development of industry operation mechanism; Finally, the construction of legislation as soon as possible, the large building project management into the orbit of legal system.
