Application of large-span steel roof construction technology for low-rise public buildings

Along with the continuous development of China's construction industry, the scale of public buildings is also expanding, especially the rapid development of high-speed railroads, making more and more complex shapes, large spans and large volumes of station buildings rigid structural roofs are widely used. Based on this, this paper takes a steel roof truss project of a school gymnasium as an example and uses theoretical analysis and empirical research to explain the application of its construction technology, so as to provide some reference for the efficient development of the construction of large-span steel roof of low-rise public buildings.
