Prospects of High Strength Bolt Connection Technology in the Future Development of Space Frame Structures

Performance Enhancement and Structural Optimization

Higher Load Carrying Capability: With the continuous progress of material science, the strength and toughness of high-strength bolts will be further improved, which is able to withstand greater tensile force, pressure and shear force, so that the space frame structure can be adapted to larger spans and more complex load conditions, providing more powerful support for the design of space frame structure of large stadiums, exhibition halls and airport terminals. It provides stronger support for the design of large-span buildings such as large stadiums, exhibition halls, airport terminals and so on.

Better seismic performance: in areas where earthquakes and other natural disasters occur frequently, the high strength bolt connection technology can make the space frame structure have better structural design flexibility under the action of earthquakes through precise preload control: the high strength bolt connection is relatively flexible, which is convenient to realize the connection between different components in the space frame structure, and provides technical guarantee for innovative space frame structural forms and complex spatial modeling, which helps architects and engineers to better realize the structural design of large-span buildings such as stadiums, exhibition halls and airport terminals. It helps architects and engineers to better realize their design concepts and create architectural works with more individuality and artistic value.

Construction Efficiency and Quality Assurance

Fast Installation: High-strength bolting technology is relatively easy to operate and fast to install, which can effectively shorten the construction cycle of the space frame structure, improve the efficiency of the project construction, reduce the cost of labor and time at the construction site, especially suitable for the projects with strict requirements on the construction period.

Quality control: the construction process of this technology is easy to monitor and quality check, by controlling the preload force and torque of the bolts and other parameters, it can ensure the reliability and stability of the connection, reduce the quality problems and safety hazards in construction, and improve the overall quality and service life of the space frame structure.

Promotion of assembly construction: In line with the development trend of assembly construction, high-strength bolt connection technology facilitates the rapid and accurate assembly of prefabricated components of the space frame structure on site, realizes the organic combination of industrialized production and on-site assembly, improves the level of construction industrialization, and promotes the transformation and upgrading of the construction industry.

Durability and Maintenance Cost Reduction

Enhanced corrosion resistance: In the future, the surface treatment technology and protective coatings of high-strength bolts will be continuously improved to provide better corrosion resistance, which will enable them to maintain good connecting performance for a long period of time in harsh natural and industrial environments, reduce the number of structural damages and repair and replacement caused by corrosion, and reduce the maintenance cost.

Reusability: High-strength bolts usually have good reusability, in the demolition and transformation process of the space frame structure, the qualified bolts can continue to be used, which not only saves resources, but also further reduces the project’s full life cycle costs.

Intelligent and Digital Application

Health Monitoring and Maintenance: Combined with the Internet of Things, sensors and other technologies, the high-strength bolt connection parts can be installed with intelligent monitoring equipment, real-time monitoring of the bolt’s stress state, pre-tensioning force changes, fatigue damage and other information, and through the data analysis and early warning system, potential safety hazards can be found in time to provide a scientific basis for the maintenance and management of the space frame structure to realize the intelligent maintenance decision-making.

Digital design and simulation: The use of digital technology for accurate modeling and simulation analysis of high-strength bolt-connected space frame structure can optimize the design parameters such as the arrangement of bolts and the value of the preload force, so as to improve the performance and reliability of the structure, and also simulate and optimize the construction process in the virtual environment, so as to solve the problems that may arise in the construction in advance.

Sustainability and Environmental Advantages

Material Sustainability: The materials used for high strength bolts will pay more attention to environmental protection and sustainability, such as the use of high-strength, high-performance green steel or other recyclable materials, reducing the dependence on non-renewable resources, and lowering energy consumption and environmental pollution in the process of material production.

Removability and recycling: the removability of high-strength bolts is conducive to the dismantling and recycling of the space frame structure at the end of its service life, which facilitates the classification, recycling and reuse of structural components and connecting parts, in line with the concept of sustainable development, reduces the generation of construction waste and lowers the impact on the environment.
