The Development of the Structural Form of Gas Station Canopy
Since Portland cement was invented in 1824, after half a century of research and development, it was not until the middle of the 19th century that concrete structures began to be applied. Because the quality of concrete and cement was relatively poor at that time, and the theory of design technology had not yet started, the development was relatively slow. At the end of the 19th century and the beginning of the 20th century, China began to build buildings with reinforced concrete structures, such as Shamian in Guangzhou and The Bund in Shanghai. However, when our country was first established, the steel output was very low, only 1.35 million tons per year. At that time, the construction of steel structures in China could only rely on the economic and technical assistance of the Soviet Union. It can be seen that the appearance of reinforced concrete structures in China was earlier than steel structures. The structure of the gas station canopy in China was a reinforced concrete frame s...
