Research and application of a new super-long span roof based on cable structure

摘要

With the continuous development of urban processes, people's demand for large-span space is getting stronger and stronger, and the application of large-span building structures is becoming more and more extensive. This paper introduces a new type of suspension cable roof that uses the building's own weight to increase the tension of the cable to achieve a super-long span. The rationality of the structural system is analyzed, and the dynamic performance, wind resistance, and seismic performance of the structure are analyzed with a simple example. At the same time, measures to further improve the structural span are proposed. Finally, it provides the forms of building that are feasible in this structural form, which provides reference and guidance for the design and construction of long-span buildings, which is of great significance.
