The high-performance steel structure in the spatial design refers to highperformance steel structure, which is different from the steel structure of the traditional steel material. With the modernization of modern architectural space, the requirements for the structure are wider, higher and irregular, and the demand for space experience is deeper. Therefore, the high-performance steel structure in space design is of great significance to the fashion of space design. This paper introduced the steel structure, detachable structure and connection structure of steel structure, analyzed the case of fashionable buildings based on the above structure. From the perspective of visual and tactile analysis, the building based on high-performance steel structure has a dynamic balance beauty, high-tech beauty and other characteristics. The high-strength, weather-resistant, antibacterial properties of high-performance steel materials were also introduced, and the spatial design cases based on the above characteristics were analyzed. The analysis showed that special performance can help people establish new trust relationships with space and new aesthetic cognition. Finally, we put forward the imagination of the future spatial design based on the high performance of the steel structure. The high-strength steel is suitable for the building with strong performance, the tension structure is suitable for the interactive space design, and the steel with the influence of light is suitable for the personalized building skin design.
