Super Large Span & Flexible Exhibition Space
•The span can reach 30-250 meters, and the roof adopts spatial structure forms such as grid structure, truss structure and cable dome structure, which can realize a large-area column-free space [7][8]. It can flexibly layout exhibition halls, cultural relics storage rooms, academic research rooms, public service areas and other functional areas, avoid sight blocking caused by supporting columns, and meet the display needs of large-scale cultural relics, large-scale exhibitions and special-shaped exhibition layouts. The large-span space can also realize multi-layer and multi-functional space division, such as the spiral ramp design in the museum, which not only enriches the spatial sense, but also provides a smooth visiting flow .
Light Weight & High Structural Strength
• The main structure is made of high-quality high-strength steel (Q355B, ASTM A36, etc.), which has excellent tensile and compressive strength [5]. The weight of the steel structure is only 1/3-1/5 of that of the traditional reinforced concrete structure, which can effectively reduce the load of the foundation project, save the cost of foundation construction, and adapt to the complex geological conditions of the museum construction site (such as coastal areas, plateau areas and earthquake-prone areas). At the same time, it has strong wind resistance, seismic resistance and snow load resistance, and the steel structure has good rigidity, which can effectively avoid structural deformation, ensure the stability of the museum during long-term use, and provide a safe storage and display environment for cultural relics.
Flexible and Beautiful Appearance & Cultural Integration
The steel structure has strong plasticity, and can be designed into various shapes such as curved surface, streamline and special shape according to the urban cultural characteristics, cultural heritage connotation and architectural aesthetics . For example, the shape imitating cultural relics (Jade Pig Dragon), the shape of a sailing ship, or the shape integrating regional cultural symbols, which can not only meet the functional needs, but also become a landmark cultural building of the city, integrating regional cultural connotation into the architectural design, showing the unique cultural charm of the region . The roof can be equipped with light-transmitting membrane materials or glass curtain walls to achieve good lighting effects, create a bright and comfortable visiting environment, and at the same time reduce energy consumption, realizing the perfect integration of architecture, culture and art.
Excellent Environmental Protection & Cultural Relic Protection Performance
The steel structure has good thermal insulation, sound insulation and moisture-proof performance. Through scientific structural design and matching of environmental protection materials, it can effectively control the indoor temperature, humidity and air quality, meet the strict environmental requirements of cultural relics storage (constant temperature and humidity), and avoid cultural relics damage caused by environmental changes . The steel materials can be 100% recycled and reused, which conforms to the global low-carbon and environmental protection development trend. No a large amount of construction waste is generated during the construction process, which reduces environmental pollution and realizes green and sustainable construction.
High Prefabrication Degree & Efficient Construction
The main components (steel grid, steel columns, curtain walls, etc.) are prefabricated in the factory with standardized production, which ensures the precision and quality of the components [2][8]. The on-site construction only needs hoisting and assembly, and advanced technologies such as BIM digital pre-assembly, segmented hoisting and hydraulic synchronous lifting are adopted to greatly reduce on-site wet work, shorten the construction period, and the construction efficiency is 50%-70% higher than that of traditional concrete museums. It can realize rapid delivery and put into use earlier, reducing the impact on the surrounding cultural environment and cultural relics protection work.
Intelligent & Multi-functional Integration
It can be integrated with intelligent cultural relics protection systems, such as constant temperature and humidity control system, intelligent monitoring system, anti-theft alarm system and digital display system, to improve the level of cultural relics protection and the visiting experience of visitors . The internal space can be flexibly divided, which can not only meet the basic functions of cultural relics storage, display and research, but also set up public service areas, academic exchange halls, cultural and creative areas, digital experience areas and other supporting spaces to realize multi-functional integration and improve the comprehensive utilization rate of the space.
