Abstract:
Steel structure is known for its advantage of high strength, light self-weight, good seismic performance, fast construction speed, and green sustainable development, which had a rapid development in the 30 years after the reform and opening up. Over the past decade, the proportion of steel structures used in high-rise buildings such as residential buildings and high-rise industrial buildings has significantly increased. Various steel structure systems have also seen new developments in super high-rise buildings. The design for seismic performance, energy dissipation and shock absorption technologies, and the promotion of high-performance steel materials have enabled steel structures to exert greater advantages in high-rise construction. However, compared to foreign advanced technologies in high-rise buildings, there is still a significant gap in material performance, structural design methods, and economic aspects of steel structures in our country. It is necessary to promote interaction across the entire industry chain and further develop related technologies.

Abstract:
The mechanical properties of aluminum material and its comparison with steel are introduced. The application history of aluminum alloy structure is reviewed. In the 1940s, the developed countries such as the United State, Britain and Germany began to build aluminum bridges.Since the 1950s, Britain, the United State, and the Soviet Union began using aluminum material in various civilian buildings, such as hangars, botanical gardens, warehouses, and museums, mostly in the form of plate joint and spherical dome.During the period of 1996 to 2010 after the reform and opening-up in China, nearly 20 aluminum structures were established, of which about half adopted the imported structural system with plate joint and spherical dome shapes, while the other half used independently developed aluminum bolt-ball lattice trusses. In the past ten years since 2010, aluminum structures have obtained rapid development in China, with more than 30 aluminum grid structures built so far. The plate joint type has become the main form of aluminum grid structures.However, various new plate joints with higher shear resistance and bending stiffness have been studied and applied in real projects.The dome shape of aluminum grid structures has also been expanded to free-form shapes, flat roof, shallow shell with large opening, and suspended shapes. The production equipment and manufacturing process of H-section with height larger than 500 mm and "日" type sections were successfully developed and applied in real engineering projects. The national standard "Technical Standard for Aluminum Structures" has been completed, which was compiled based on the revising and merging on the original national standards "Design Code for Aluminum Structures" and "Construction Quality Acceptance Code for Aluminum Structures". China in the field of aluminum structures from the introduction, imitation, to independent innovation, has developed into a major and powerful country for research and application.

Abstract:
Power station boilers are one of the three main engines in thermal power plants. After more than 30 years of rapid development, China’s power generation technology has made a leap from 300 MW subcritical to the world’s largest 1 000 MW ultra-supercritical technology, with the largest operational thermal power units domestically reaching 1 350 MW. China’s power plant boilers have developed rapidly,, owning the largest boiler design, manufacturing, and operation technologies in the world. In recent decades, most of the new large-scale power plants constructed globally have been primarily located within China. In recent years, environmental protection and energy conservation have become important directions for structural adjustment in China’s electric power industry. Through technical renovations of furnace combustion and tail-end emissions in boilers, thermal power plants have met or exceeded national environmental protection standards. Thermal power plays a ballast stone role in China’s national economy.
Due to the entire boiler being suspended from the top plate layer of the boiler steel structure, significant force is applied to this top layer. For large boilers, a horizontal split girder is used for the main girder, with girder section heights exceeding 10 meters. The boiler steel structure bears the static load transmitted from the boiler itself and users; the horizontal loads of the boiler body are transferred to the boiler steel structure through guide devices. Boiler guide devices, together with boiler buckstays, determine the expansion center of the boiler and transmit the horizontal forces such as seismic forces of the boiler, wind loads, and unbalanced forces from the rear flue gas ducts to the steel structure.
The entire boiler steel structure uses pure steel components, mostly arranged outdoors. In cold regions or where there are specific needs, full or partial tight enclosures may be adopted. Boiler steel structures are complex, with a large number of components, fully bolted connections, and large components such as large horizontal split girders, making the design, fabrication, and inspection relatively complicated. Many beams in large boiler steel structures use hot-rolled H-sections and other hot-rolled sections. However, because most columns, beams, and vertical supports bear significant loads, hot-rolled sections cannot meet the requirements, leading to extensive use of plate-spliced I-sections, cross shaped, or box sections.
There are still many aspects in the field of boiler steel structure that need innovation and improvement. The Boiler Steel Structure Branch of the China Steel Structure Association has been committed to guiding the industry’s technological development and self-discipline. It has organized member units to write many standards for design, manufacturing, inspection, appraisal, reinforcement, and other aspects. Boiler steel structures require technological research and innovation in design and manufacturing, domestic software development, application of high-strength steel, design and application of steel tube concrete structures, research and application of buckling restrained supports, and development of new products. It is necessary to further establish a more complete industry standard system.

Abstract:
Compared with traditional concrete structures, steel structures have gradually been widely used in the construction industry due to their light weight, high strength and easy forming. Since the end of the 19th century and the beginning of the 20th century, the application of steel structure has been expanding, especially in high-rise buildings and stadiums. The development of steel structure in China started late, but with the rapid advancement of urban construction, especially the opportunity of the 2008 Beijing Olympic Games, numerous innovative buildings have emerged, which has promoted the progress of steel structure technology.
There is no strict standard for the definition of complex architectural steel structure, and this paper discusses it from the perspective of processing and manufacturing process. The development of complex architectural steel structure in China can be roughly divided into three stages: the first stage (1990s): projects such as Shanghai Grand Theatre used welded box and steel pipe truss structures with complex configurations. The second stage (from the early 2000s to the mid-2010s): the construction of projects such as the National Stadium marked the rapid development of steel structures for complex buildings. Phase III (more than a decade ago): With technological innovation, all kinds of complex steel structures have emerged, such as the Shanghai Centre Tower.
Complex steel structure is mostly used for the exposed components of special architectural shapes, or the node structure is particularly complicated due to the complexity of the building structure. Common applications include shaped cross-section members, space curved surface members and so on. The processing and manufacturing technology of complex steel components mainly focuses on the following aspects: deepening design technology: from manual drawing to CAD, and then to the establishment of BIM model, to improve the design efficiency and accuracy. Development of special equipment: such as multi-dimensional coherent line cutting machine and large-stroke end milling machine, etc., to improve processing accuracy and efficiency. Shaped cross-section member forming technology: adopting a variety of processes, such as cold processing, hot processing and sample box testing, to meet the processing needs of complex members. Steel pipe bending forming technology: including hot bending and cold bending methods, applicable to the processing of steel pipes with different curvature radii. Processing of large-caliber steel pipes and conical pipes: adopting rolled and pressed forming processes, applicable to steel pipes of different calibers and shapes.

Abstract:
Nine departments including the Ministry of Housing and Urban-Rural Development of the People’s Republic of China jointly issued the "Guiding Opinions on the Coordinated Development of Intelligent Construction and the Building Industrialization". The opinions propose to accelerate the upgrading of building industrialization, digitalization and intelligence, promote the transformation of construction methods and drive the high-quality development of the construction industry. Steel structure buildings are widely used in large factories, stadiums, super high-rise buildings, bridges and other projects due to their light self-weight, diverse shapes and simple construction. According to the strategic consulting report of the Chinese Academy of Engineering, compared with reinforced concrete buildings, steel structure buildings can reduce carbon emissions by 15%, dust by 59%, solid waste by 51%, and save 12% of energy consumption and 39% of water consumption. More than 80% of the components of steel structure buildings can be processed in factories, and the production and processing equipment is relatively complete, which is very suitable for combination with intelligent manufacturing to improve the quality, efficiency and safety of construction projects. In order to realize building industrialization and intelligence and change the current production mode of the industry, this paper expounds the development process of the integration of steel structure buildings and intelligent manufacturing technologies in the past 30 years since the reform and opening up through the method of literature review, focuses on describing the practices of advanced technologies such as robotics, the internet of things, big data and artificial intelligence in steel structure manufacturing, and strives to provide practical guidance and references for the intelligent upgrading of steel structure manufacturing.

As long as the inertia moment, axial force and length of each column segment are given, the effective lengths can be computed directly and with excellent accuracy by solving a quadratic or a cubic equation. The proposed approach is suited for programming and spreadsheet computation, and may be used to replace clause 8.3.2, clause 8.3.3 and Table E.0.3 to E.0.6 of the Code GB 50017-2017.
